Computed Tomography (CT) Scan
Scheduling Office: (413) 664-5405 (Mon-Fri 8 a.m. - 5:15 p.m.)
NARH’s Brilliance CT Scanner performs very fast and more comfortable exams, and now uses low-dose scanning technology to deliver high quality images with less radiation. The scanner collects all the data it needs with just a single pass, conducts multi-slice scanning, and can construct the image in 3-D from a single scan. CT can show several types of tissue--lung, bone, soft tissue, and blood vessels.
CT angiography can be performed to detect problems with blood flow in the arteries, such as blockages or narrowing of the arteries.
Sinus, spine, extremity and abdominal/ pelvic scan for kidney stone requires no preparation. For abdominal and/or pelvic scans you will also be given a liquid contrast to drink at home.
Some scans require an injection of contrast media. This contrast is excreted by the kidneys and so current blood tests to check renal function are to be done prior to the scan. The blood tests are to be done within 7 days of your appointment. Drink plenty of fluids following your exam to flush the contrast out of your system.
Once in the CT Scan room, a technologist will position you on the scan table, which will move you through the opening where the x-ray tube is contained. You will hear some noise with each exposure and the table will move slightly. You can speak to, and receive instructions from, the technologist during the examination. For some scans, you will be instructed to hold your breath. During all scans, it is important to hold still.
The scans themselves take only a few minutes but you may be in the department for an hour or so.
