A virtual colonoscopy uses computed tomography (CT) scanning to screen for polyps and masses in the large intestine or colon that could be precancerous or cancerous. Yale Medicine’s radiologists interpret these images and generate a consultation report on the findings that an ordering provider can review.
Jay Pahade, MD, a radiologist, says the state-of-the-art CT scanner that Yale Medicine radiologists use for the procedure has been designed and calibrated to take the clearest possible images of the colon using the least amount of radiation possible.
At Yale Medicine Department of Radiology & Biomedical Imaging, “We’re focusing the scan on the interior of the colon and not the other organs in the abdomen/pelvis,” he says. “So we’re able to use substantially less radiation than most CT scans require.”
