Computerized Tomography
Please allow 30 minutes to an hour for CT exams.

Valley Diagnostic Imaging Services- Olympic Building has recently invested in a special CT to help physicians reach confident diagnoses and provide a higher level of patient care. The new LightSpeed VCT XTe from GE Healthcare enables the lowering of radiation dose
up to 40% across the entire body while maintaining high quality images throughout the body.

A CT, computerized tomography (or CAT) scan is a special examination in which multiple "slices" or pictures are taken through an area of the body. You will be placed on a table which will move you into the scanner. After each "slice" is taken the table will move a small distance to take the next picture. For many CT scans, contrast material will be injected into your vein. Please bring any previous CT films which have been taken in the past year.

In addition to the radiation dose reduced by the CT scanner, Vantage Radiology is pleased to be the first group in the area to use new CT radiation shield absorbers. These radiation shields cut down the amount of radiation exposure by 40% - 60% to the soft tissues. Three types of shields have been created to limit radiation absorbed by the eyes, thyroid, and breast tissue during CT examinations. Each shield is crafted to fit these specific body parts, eliminating artifacts that may disrupt the clarity of the images.

What if you could lower your handicap by 40%?

Coronary CT Angiogram

Coronary CT Angiography (CCTA) is a special kind of CT scan (x-ray study) that provides high resolution pictures of the heart (coronary) artieries. This quick outpatient study can determine if there are blockages to blood flow (plaques) due to hardening of the arteries using only an IV injection of iodine containing contrast ("x-ray dye").

Preparation:
It is very important to have a low and regular heart rate in order to get the best quality study, and you will be receiving a dose of sublingual nitroglycerin. As a consequence, you must:

  • On the day of procedure, refrain from any exercise prior to the exam.
  • Refrain from any caffeine for 12 hours (coffee, tea, sodas, etc.) before the procedure.
  • Refrain from any nicotine for 12 hours before the procedure.
  • Refrain from any stimulant medications for 12 hours (decongestants, antihistamines, etc.) before the procedure
  • Refrain from Viagra for at least 48 hours and Cialis and Levitra for at least 72 hours before the procedure.

Also, you must not eat for 4 hours prior to the procedure, although you are encouraged to drink 2-8 ounces glasses of water during that period.

Wear comfortable, loose fitting clothes with either short sleeves, or sleeves which can be easily rolled up without constricting the upper arm.

Take the medication that you are given 2 hour before you arrive for your study.

Please be prepared to be at the imaging clinic for 60-90 minutes for the entire process. This allows us time to review your paperwork, start the IV, and possibly administer more medication if your heart rate remains high after the first dose.

CT Colonography

CT colonography is a FDA approved, non-invasive procedure, which screens for colorectal cancer. CT colonography uses state-of-the-art CT images as well as 3D simulated images to evaluate your colon. A radiologist uses 2D and 3D simulated images to “see inside” your colon in order to identify pre-cancerous polyps and tumors. The radiologist is also able to identify some other abnormalities outside of the colon from the abdominal CT exam.

Preparation:
Patients must follow a clear liquid diet the day before and the day of the exam. At no time in these two days are you to have solid food. You will be able to go back on a regular diet as soon as the exam is completed.

  • Follow the instructions on the inside of the Lo So Prep package. Drink the bottole of liquid Magnesium Citrate at the same time as when you drink the LoSo Prep powder packet of Magnesium Citrate in the package.
  • Along with the Lo So Prep instructions, you will need to take one bottle of Tagitol with each clear liquid meal at breakfast, lunch and dinner time. At the end of the day, you should have taken a total of three bottles of Tagitol.
  • Please drink plenty of clear fluids. The more fluids you drink, the cleaner your colon will be.

You should continue to take prescribed medications as you normally would. This procedure should not cause you to miss or skip doses of your daily-prescribed medications. **Do NOT skip your blood pressure or heart medications** if needed, you can take over the counter medications such as aspirin, Ibuprofen(Motrin), and Acetam inophen(Tylenol). Avoid taking your regular medications within 2 hours of your CT colonography prep medications to avoid absorption issues.

If you normally take pills orally for diabetes twice a day, on the day prior to your exam take the AM dose but skip the PM dose. On the morning of the exam, wait to take your AM dose after the exam is completed and once you start eating regular solid food again. If you normally take one pill orally for diabetes once a day, on the day prior to your exam take the dose in the morning. On the morning of the exam, again, wait to take your pill for diabetes after the exam is completed and you are back on a regular diet again.

CT Calcium Scoring

The Calcium Score is a measure of the amount of calcium located in the coronary arteries. Healthy coronary arteries are free of plaque and should have a score of zero (no calcium seen). A positive test means: calcium deposits were found in the coronary arteries, indicating at least some degree of coronary artery disease. The amount of calcium is related to the amount of disease, and guides further testing. A negative test means: no calcium deposits were seen, so most likely there is little or no coronary disease and he risk of heart attack is very low.
