Computed Tomography - CT
Computed Tomography (CT), formerly known as a CAT scan, uses X-ray and computer equipment to produce cross-sectional images of body structures, tissues, and organs. CT imaging provides the unique ability to visualize soft tissue, bones, muscle, internal organs, and blood vessels.
What are some common uses of CT?
- Planning and proper administration of radiation treatments for tumors.
- Planning surgery.
- Quick identification of injuries to the liver, spleen, kidneys, spine, head, or other internal organs in cases of trauma
- Detecting pneumonia, bronchitis, cancer, metastasis, kidney stones, stroke, tumors, and intestinal abnormalities.
Preventative Medical Screenings
CT Screening - Lung: Formal academic studies have documented potential value in detecting lung cancer at earlier stages, when the cancer can still be surgically removed. We also offer CT Calcium Scoring which measures the amount of calcified plaque in the arteries of the heart.
Griffin Imaging Mako Approved
Griffin Imaging is also Mako SmartRobotics Cat-Scan protocol approved. Mako is a 3-D CT based software which allows a surgeon to take a look at a patient’s anatomy and create a plan for knee, hip, or joint surgery.
Griffin Imaging tailors CT examinations by utilizing hardware and software that is provided by the CT vendor to minimize exposure to patients. Our current CT scanner adjusts exposure levels during the scan within the limits of the protocols.
What should I expect during this exam?
A CT examination usually takes between five minutes and half an hour.
- The technologist will position you on the CT table. Pillows will be used to help you keep still in the proper position during the scan. The table will move slowly into the CT scanner opening. Depending on the area of the body being examined, the increments of movement may be very small and almost undetectable or large enough to feel the motion.
- To enhance the visibility of certain tissues or blood vessels, use of different contrast materials may be required. Depending on the type of examination, these materials may be injected through an IV or swallowed. Before receiving the contrast material, you should inform the radiologist or technologist of the following:
- Any allergies, especially to medications or iodine.
- Any information regarding a history of diabetes, asthma, kidney problems, or heart conditions. These conditions may indicate a higher risk of reaction to the contrast material or potential problems with eliminating the material from your system after the exam.
- If you are pregnant or think you may be.
- You will be alone in the room during your scan; however, you can communicate with your technologist at all times through an intercom system, and they will be able to see, hear, and speak with you throughout the entire exam.
What will I experience during this exam?
CT scanning is a painless procedure. Depending on the type of scan needed, individual preparations may differ. Here is an overview of what to expect from the different methods we use to administer contrast materials:
- Mouth: A member of our staff may ask you to drink the contrast material, a liquid that allows the radiologist to better see your stomach, small bowel, and colon. Some patients find the taste slightly unpleasant, but tolerable.
- IV injection: To accentuate the difference between normal and abnormal tissue in organs, such as the liver or spleen, and to better define the blood vessels and kidneys, a contrast material is commonly injected into a vein. You may feel flushed and may have a metallic taste in your mouth, which should pass in a minute or two.
- Labs may be required to determine your kidney functions prior to the IV injection. Please consult with your referring provider.
