CT Scan (Computed Tomography)
A CT Scan (or CAT scan) is a diagnostic imaging test that uses an intricate method of x-ray taking and current computer technology to display two and three demensional images of internal structures of the body on a computer screen. It is one of the most common imaging technologies used today for screening and diagnosing various conditions and diseases. These exams are non-invasive and painless and allow for a more accurate diagnosis than a traditional x-ray.
At Tolland Imaging Center, our multi-slice Hitachi Supria provides our board-certified Radiologists with extremely detailed images and rapid scanning time for patient comfort. Current computer software applications applied to images post-scan optimize the data and provide the radiologist with additional views for a comprehensive review and report of the exam. CT Scans can be performed if you have an implanted medical device.
Additionally, The American College of Radiology (ACR) has recognized Tolland Imaging Center as a Lung Cancer Screening Center. This is a voluntary program that acknowledges facilities that prioritize safe and effective diagnostic and follow-up care for individuals who are at high risk of developing lung cancer.
Tolland Imaging Center offers the following CT procedures to our patients:
- Brain/Head
- Neck
- Chest (Lungs)

Frequently Asked Questions about CT Scan
Yes. A CT scan is made up of a series of x-rays which are processed by a computer to produce cross-sectional pictures of the body. These cross-sectional images allow one to look at the inside of the body just as one would look at the inside of a loaf of bread by slicing it. A CT scan is thus made up of a series of slices.
Tolland Imaging Center offers low-dose CT Scanning technology to reduce exposures to radiation. CT scan risks are similar to those of conventional X-rays, which are very minimal.
Contrast agents are used to image tissues and structures that are not normally seen, or not seen very well. Intravenous contrast agents are used to enhance organs and visualize blood vessels. Oral contrast agents are used to visualize the digestive tract. Please let us know if you have any allergies or kidney or liver problems.
Most abdominal scans require the patient to drink a barium sulfate oral contrast mixture. This mixture is flavored and not at all unpleasant. Oral contrast highlights the stomach and upper intestine providing the radiologist with a detailed image for review.
Depending upon your condition and the images required to diagnose or rule out pathology, X-ray dye or intravenous contrast may or may not be needed. The radiologist reviews the information sent to us by your physician and decides what contrast is needed to provide the best images.
If you have had a reaction to X-ray dye in the past, or have ever had an anaphylactic reaction to anything in the past, please let us know. Please consult your primary physician or our staff Radiologist for details.
Different types of exams require different preparation. Please call our office if you have any questions regarding your specific exam.
You may take your medication(s) as prescribed by your doctor. Please let our staff know what medications you have taken the day of your exam and call your doctor with any questions prior to your exam.
CT scanning causes no pain, just as a routine X-ray is painless. If intravenous contrast is used, you may feel warm and flush and get a metallic taste in your mouth. These sensations normally disappear after a few minutes.
Patients may be asked to wear a gown for some scans. In addition, removal of glasses, jewelry, dentures, hearing aids, or anything else that could interfere with the scan may be required.
You will need to hold as still as possible; patient motion can compromise image quality.
Your doctor should receive a written report in 1 to 2 business days. If requested by your physician, a report can be called to him/her the day of the exam. You can get the results from your doctor.
