Q: What is a Heart Scan or Coronary Calcification Scoring?

Coronary artery calcification scoring is a pain free, non-invasive procedure that requires less than ten minutes. The multi-detector CT scanner takes 120 images of your coronary arteries without any injections, needles or catheters. Four EKG electrodes are placed on your chest to obtain images while your heart appears motionless. The amount of calcium or plaque detected in your coronary arteries is then used to establish your cardiac score.

Back to questions

Q: What Does the Heart Scan Coronary Calcification Score tell My Physician and Me?

Very early warning signs of heart disease can be detected with cardiac scoring. This is the latest tool available to detect plaque in the coronary arteries. There are five categories for calcium scores.

1.) A Score of 0 - No coronary artery disease

2.) A score of 1-11 - Indicates a minimal risk of coronary artery disease

3.) A score of 11-100 - Indicates a mild degree atherosclerotic, plaque burden

4.) A score of 101-400 - Indicates a moderate atherosclerotic plaque burden

5.) A score greater than 400 - Indicates an extensive atherosclerotic plaque burden

In addition to the total score, a percentile for age and gender is calculated. If the score >75 percentile for a patient's age/gender, then the physician will advance to recommendations for next higher calcium score range. With this information, you and your physician can formulate the appropriate treatment, which could include diet and life style changes, medications, and/or further testing.

The following is adapted from Rumberger JA, et. al., Mayo Clinic Proceedings March 1999;74:243-252

CT CALCIUM SCORE OF 0:

No identifiable plaque. The probability of significant Coronary Artery Disease (CAD) is very unlikely, generally < 5%.  The implications for Cardiovascular (CV) risk are very low. The recommendations are to discuss general public health guidelines for primary prevention of heart diseases.

CT CALCIUM SCORE OF 1-10:

Minimal identifiable plaque burden. The probability of significant CAD is very low, < 10%. The implications for CV risk are low. The recommendations are to discuss general public health guidelines for primary prevention of heart diseases.

CT CALCIUM SCORE OF 11-100:

Definite, at least mild atherosclerotic plaque burden. The probability of significant CAD-mild or minimal coronary stenosis likely. The implications for CV risk are low to moderate. The recommendations are to counsel about risk factor modification, strict adherence with National primary prevention guidelines for high cholesterol. Consult your physician.

CT CALCIUM SCORE OF 101-400:

Definite at least moderate atherosclerotic plaque burden. The probability of significant CAD-non-obstructive CAD highly likely, although obstructive disease possible. The implications for CV risk are moderate to high. The recommendations are to institute aggressive risk factor modification and secondary prevention guidelines for high cholesterol. Consult your physician.

CT CALCIUM SCORE >400:

Extensive atherosclerotic plaque burden. The probability of significant CAD-high likelihood (>=90%) of at least 1 significant coronary stenosis. The implications for CV risk are high. The recommendations are to institute very aggressive risk factor modifications. Consult your physician. 

Back to questions

Q: Is Coronary Artery Disease Treatable?

Yes. Prevention, early detection, and early intervention are critical and can save many lives. Coronary artery atherosclerosis can be slowed, stabilized, and in some cases reversed through aggressive life-style modification and also through medical therapies under the supervision of a physician.

Back to questions

Q: Who Should Have the Heart Scan?

Coronary Calcium scoring is not for everyone. In general, it is most appropriate for men and women, age 40-70, who have one additional risk factor. It is not for people with already known coronary heart disease, arrhythmia's, or previous heart surgery. The scan could be the first step in preventing a major fatal cardiac event. The American Heart Association now recommends the heart scan as one of the first tests for atypical chest pain. Learn More.

Back to questions

Q: How Do I Prepare for the Heart Scan Examination?

There is no specific preparation for the scan. You may eat or drink, however caffeinated products may make your heart beat too fast. Avoid shirts with metal straps or buttons.

Back to questions

Q: What is a Lung Scan or CT Lung Screening Examination?

In general, a screening exam is a study used to detect a disease process before signs or symptoms are present. For example, mammography detects early breast cancer. Colonoscopy detects early colon cancer. A lung cancer screening CT exam is a sophisticated low radiation exam utilizing a Multi-detector CT scanner to look for early lung cancer. Special protocols are used to screen for early lung cancer.

Back to questions

Q: What Does the CT Lung Scan Tell My Physician and Me?

In many cases, the lung scan will be normal. In other cases, a variety of lung abnormalities might be detected which would otherwise not be detectable on plain chest x-rays. Many of these abnormalities will be benign; that is, they will not be cancer and do not require any treatment or follow-up. Some non-cancerous abnormalities require follow-up testing to establish stability. Early research has shown that approximately 40-50% of people may have a non-cancerous nodule, which requires tracking for stability. This finding will usually require following the nodule for two years. If a suspicious nodule is detected, you will be immediately referred to a lung specialist. It may be necessary for you to undergo further testing to determine if such a suspicious abnormality is cancer.  The following chart provides a review of codes assigned, based on lung scan results. These codes are used to assist in patient tracking and follow-up procedures:

A low dose CT lung scan is a screening exam and does not preclude further diagnostic work-ups should symptoms arise. If you develop symptoms (cough, pain), please see your physician. Not all lung cancers will be detected with low dose CT screening and a negative screen today does not mean that a cancer will not develop in the future. CT lung cancer screening is not a substitute for smoking cessation.

Back to questions

Q: What are the Benefits of a CT Lung Scan Examination?

Low dose CT scanning of the lungs can greatly improve the detection of small and potentially curable early stage lung cancers; this has been shown in the ELCAP Study (Early Lung Cancer Action Project). (Henschke, CI, and et al early lung cancer action project: overall design and findings from baseline screening. ('The Lancet 1999: 354: 99-105'). Learn More.

Back to questions

Q: Who Should Have the CT Lung Scan?

The CT lung scan exam is not for everyone. In general it is most appropriate for men and women 50+ with a significant smoking history. It is not for people with known lung cancer. After scheduling this exam a St. Paul Radiology nurse will contact you to ensure the procedure is appropriate for you.

Q: What is the CT Colonography Examination?

In general, a screening exam is a study used to detect a disease process before signs or symptoms are present. For example, mammography detects early breast cancer. A CT Colonography exam is a sophisticated low radiation exam utilizing a multi-detector CT scanner to look for colon cancer and colon polyps. Special protocols are used to enhance the screening examination. A small tube is placed into the rectum through which carbon dioxide is used for insufflation. This distends the colon, allowing St. Paul Radiology physicians to obtain detailed CT images. No sedation is required, there is minimal patient discomfort, and the procedure time is short.

Back to questions

Q: What Does the CT Colonography Examination Tell My Physician and Me?

This procedure provides detailed information on your colon health, including the detection of significant colon polyps and colon cancers.

Back to questions

Q: What Are the Benefits of a CT Colonography Examination?

Colon cancer is the second leading cause of cancer death in the United States for both men and women. However, less than half of the population is currently screened for colon cancer. Although the potential risk is clear, many people are reluctant to undergo screening because of the perceived discomfort associated with traditional screening exams. CT colonography offers patients an efficacious alternative to colonoscopy for screening.

Back to questions

Q: Who Should Have a CT Colonography Examination?

The CT colonography exam is not for everyone. In general it is most appropriate for men and women over 50. It is not for people with known colon cancer, colon cancer symptoms, or previously removed colon polyps. After scheduling this exam a St. Paul Radiology nurse will contact you to ensure the procedure is appropriate for you.

Back to questions

Q: How Do I Prepare for the CT Colonography Examination?

Patients will be provided a dietary prep kit with instructions prior to the exam. The kit includes a recommended menu to be followed for two days before the exam. The St. Paul Radiology nurse will review these instructions with you to ensure adequate preparation. As with colonoscopy, adequate dietary preparation impacts exam quality. This diet, combined with the colon cleansing medicines provided in the kit, will remove stool from your colon. This allows St. Paul Radiology physicians to detect any polyps or masses that may be in the colon. If stool remains in the colon, it could hide a polyp or could be confused with a polyp.

Back to questions

Q: Is the CT Colonography Examination Safe?

Yes. Radiation exposure is minimal. No needles, injections, or sedations are used.

Back to questions

Q: Is the CT Colonography Examination Painful?

No. Most patients feel minimal discomfort during the exam. Some patients report cramping during colon insufflation; however, this is short-lived.

Back to questions

Q: How Do I Receive Results From the CT Colonography Examination?

After your scan, one of the St. Paul Radiology Board Certified Radiologist will interpret your scan, comprised of several hundred images. You will then be telephoned within 72 hours by either the Health Scan nurse or attending radiologist with your exam results. Your results and medical report will also be shared with your primary care physician, with your approval.

Back to questions

Q: How Long Does the CT Colonography Examination Last?

Although the scan takes less than ten minutes, you should allow one hour for the entire procedure. You do not need a driver to accompany you.

Back to questions

Q: Is the CT Colonography Examination Covered by Insurance?

No. Currently the CT Colonography exam is considered preventive for asymptomatic patients. As such, it is not currently covered by insurance.

You will feel the compression when it is applied for each image. Unless your breasts are already tender, the exam should not be painful. Some patients do experience brief discomfort.

Back to questions

Q: What is Computer Aided Detection (CAD)?

St. Paul Radiology is equipped with state-of-the-art Computer Aided Detection (CAD). This new technology aids the radiologist in identifying very subtle changes in the breast. CAD, as the name implies, uses a computer to assist in analyzing your mammogram. The computer utilizes breakthrough technology to highlight any potential areas of concern on a mammogram, calling attention to subtle changes in the breast tissue that may indicate the presence of cancer. The computer does not replace the radiologist who reads the mammograms. The radiologist determines if marked areas need further evaluation. With CAD, the radiologist still makes the final interpretation of your mammograms and you receive the benefit of a second opinion.

Back to questions

Q: How will I receive my mammogram results?

A Board Certified Radiologist (a physician who specializes in interpreting diagnostic images) will study the images from your examination and send a report to your physician. You will receive a letter from St. Paul Radiology with your results within 30 days of your examination.

Back to questions

Q: What is MRI?

Your physician has ordered a diagnostic procedure known as Magnetic Resonance Imaging, or MRI. MRI uses a magnetic field, radio waves and a computer to create extremely detailed images of the human body. Before your exam begins, an MRI technologist will ask you some medical questions, explain your procedure and assist you into the MRI room. You will be asked to lie on a padded table, which will move into the magnet opening, and your exam will begin.

Back to questions

Q: What is sedation?

Sedation is the use of anesthetics to cause loss of awareness allowing patients to complete scans safely and comfortably. CRNAs use a variety of intravenous agents, custom designed to each patient’s need.

Back to questions

Q: Who needs sedation prior to an imaging exam (MRI, CT or PET scan)?

Infants and children often need sedation prior to imaging due to an inability to be still for more than a few moments, affecting the quality of the scan. Adult patients who are unable to tolerate diagnostic imaging due to uncomfortable feelings of confinement, pain or uncontrollable tremors have several options including oral valium, Open MRI or conscious sedation. Talk with your physician to see if one of these options is right for you.

Back to questions

Q: Is there any preparation on my part prior to my appointment?

The following is a list of ultrasound exams and the preparation required before your exam:

Abdomen – This exam studies the organs in your abdomen (liver, gallbladder, pancreas, kidneys, spleen and aorta). Please do not eat or drink anything after midnight prior to your exam. If you have an afternoon appointment, do not eat or drink for eight hours prior to the exam.

Pelvic or Obstetrical – Whether you are pregnant or not, you will be required to drink four 8 ounce glasses of water one hour before your appointment time. Please do not use the restroom until after your exam. Your bladder must be full in order to study the pelvic organs, and if you are pregnant, the anatomy of your baby. Your bowel lies in front of these structures/organs, and a full bladder will push the bowel away to allow a better view.

Vascular – Vascular exams are used to evaluate your arteries and veins. With Doppler ultrasound we can examine the anatomy and blood flow patterns in your vessels. No preparation is required.

Q: What should I expect during my examination?

After you enter the examination room, the sonographer will ask you some brief questions concerning your medical history and current symptoms. This information is important to your exam.

For an abdominal exam, you will not be asked to undress, but will need to uncover your abdomen. You will be asked to lie on your back on the examination table.

Pelvic and Obstetrical exams may be performed in two different ways. The first method involves moving a small probe called a transducer across your abdomen. A gel will be applied to your skin and the sonographer will apply mild to moderate pressure allowing the transducer to emit and receive sound waves to form images.

The second method uses a transducer specially designed to be placed in the vagina. You will be asked to empty your bladder and remove your underwear before this exam. The transducer will be placed into your vagina with lubricating gel and the necessary images recorded. This technique allows a more detailed exam of the adjacent structures/organs. The method to be used will be decided at the time of the exam and is based on your medical history.

Vascular exams may require you to change into a gown for easy access to the vessels being imaged. A Doppler probe will be used to evaluate the blood flow through your arteries and veins. You will hear noises similar to a heartbeat as the sonographer evaluates the blood flow through your vessels.

Q: What is a bone densitometry exam?

Also known as a DEXA scan, this procedure measures bone mineral density and can determine if you have osteoporosis. Often called the "silent disease", osteoporosis symptoms are rarely evident until bone has been lost.

The bone densitometer uses small amounts of X-ray to produce images of the spine, hip or even the whole body. The spine and hip are measured because they are where osteoporotic fractures most often occur. The X-Ray is composed of two energy levels that are absorbed differently by bones. The technical term for this method is "dual energy X-Ray absorptiometry" or DEXA. A computer is able to determine from these differences how much bone mineral is present.

Q: How does the procedure work?

Before the exam starts, the technologist will enter your name, age, weight and ethnicity into the computer. This information is used to compare your results with a normal reference population. During the bone densitometry exam, you will lie on your back on a padded table. As the exam progresses, the technologist will position your arms and legs. If you have metallic orthopedic devices in your spine or hip, your forearm or heel may be evaluated instead of the area containing metal. The information obtained during the exam will be used by your physician to evaluate bone status and fracture risk.

Q: What is a CT Scan?

Computed Tomography (CT) produces detailed images of the body, providing information about the internal organs, bones, and soft tissues and with computer generated assistance creates cross-sectional images of body tissues and organs that are used to diagnose diseases and disorders. Before your examiniation begins, a CT technologist will ask you a few medical questions, explain your procedure and assist you into the CT examination room. You will be asked to lie on a padded table, which will move into the scanner opening for the examination.
