Computed Tomography (CT)

What makes Medical Imaging unique when it comes CT?

  • Our team is capable of creating accurate images of the coronary arteries and performing non-invasive CT coronary angiography.
  • Our machine is also the latest in multi-detector technology, which means we are able to obtain images using much shorter scanning times. This ensures the procedure is more comfortable and, more importantly, exposes you to less radiation.

Some of the more advanced CT techniques we offer include:

  • CT Angiography (CTA) of the brain, neck, body and extremity vasculature
  • CTA of the coronary arteries
  • Obtaining oncology PET images and merging them with corresponding CT images to display both high-resolution anatomical detail and metabolic/functional information
  • Producing 3-D images of the heart and other body organs
  • Virtual Colonoscopy with fly-through display
  • Lung screening
  • Stroke screening
  • Dental CT
  • Cardiac Calcium scoring
  • 3-D reconstruction and reformations.

What is CT?

Computed Tomography is a non-invasive imaging method that uses powerful computers to create three-dimensional and cross-sectional pictures of the body. CT scans are rapid, which means you will usually be on and off the scanner in a matter of minutes. While PET scans provide metabolic detail (cellular activity), CT scans provide anatomical details, such as the size and location of tumors, masses, infections and injuries. CT scanners send x-rays through the body, which are then measured by detectors in the CT scanner. A computer algorithm then processes those measurements to produce pictures of the body’s internal structures.

The procedure is painless, but certain studies may require a small amount of a contrast agent to be injected into an arm vein (IV contrast) to highlight special areas and visualize abnormalities or you may be asked to drink a barium contrast (oral contrast) that will enhance the intestinal track.

If you are diabetic or over the age of 55 and your study requires a contrast injection, you will need to have a blood test to check your creatinine level prior to the CT exam. We are able to perform the blood test 20 minutes before the CT exam at our facility.

Unlike MRI, the CT scanner is not an enclosed device and should not bother claustrophobic patients.

CT Studies

•   Calcium Score
Measures the amount of calcium in the coronary artery walls and provides a numeric score that evaluates the risk of heart disease relative to your age, family history and gender.
•   CT Coronary Angiogram (CTA)
The non-invasive CT Coronary Angiogram visualizes the arterial channel or lumen. Using our 64 detector CT scanner we image the coronary arteries to detect unstable and life threatening soft plaque that projects into the lumen and creates narrowing in the arterial channels. In most patients who do not have symptoms, it is usually the unstable soft plaque that ruptures without warning, causing heart attacks and strokes. By detecting the soft plaque early and initiating aggressive lifestyle changes and interventional therapies, we may prevent premature death.
•   CT of the Chest, Abdomen and Pelvis
Detects high risk abnormalities and hidden diseases including lung cancer, kidney tumors, liver tumors, abnormalities of the prostate, ovaries, uterus, adrenal gland, spleen and gallbladder. Abnormalities in the back, including disc disease and abnormalities in the bones can also be detected.
•   Low dose CT of the lungs
This low radiation, two-minute scan detects early cancers and is an excellent screening tool for smokers, family members of smokers or anyone with a family history of lung cancer.
•   CT Angiography
Examines the blood vessels in key areas of the body, including the brain, kidneys, pelvis, legs, lungs, heart, neck and abdomen. IV contrast is used to enhance the images to show narrowing or blockages in the blood vessels caused by calcification.
•   CT Urogram
Is a CT of the Abdomen and is used to evaluate the urinary tract (kidneys and bladder).
•   Virtual Colonoscopy
The Virtual Colonoscopy, which is less invasive, is a good substitute for the traditional test. Under CT guidance, it provides a three-dimensional tour of the colon to detect polyps and tumors.

What to expect during your CT exam?

  • CT scans are very rapid tests and you should be on and off the table in a matter of minutes.
  • The CT scanner is not an enclosed machine and shouldn’t be a problem for claustrophobic patients.
  • Depending on which CT study you are having, you will be required to prepare for the test before you arrive at our facility
  • For all CT exams that require contrast, you should not eat, drink or smoke for four hours prior to the exam.
  • If the test you are having requires you to drink the oral contrast, you need to be at the facility approximately one hour before your exam.

Further preparations:

  • CT of the Chest or Neck
    You should not drink or eat four hours prior to the exam. You should not have any caffeine or nicotine products 24 hours prior to your exam.
  • CT of the Abdomen or Pelvis
    Arrive one hour before the exam to drink the contrast Do not eat or drink four hours before the exam Patients over 55 years of age need their creatinine level Let us know if you are allergic to iodine and/or shellfish Let us know if you are asthmatic or diabetic
