- Using some of the most technologically advanced equipment available
- Conducting high-level research into MRI, MRS, PET and image processing
- Using low-radiation CT scan technology for virtual colonoscopies
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 Yale Medicine radiologist and assistant professor of radiology and biomedical imaging at Yale School of Medicine, 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, “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.”
