Assessing the Benefits of CT Colonography


In a recent video interview, Syam Reddy, MD discussed the merits of computed tomography (CT) colonography, a non-invasive alternative to conventional colonoscopy, which may help reduce gaps in screening for colorectal cancer.

Preventive screenings decreased significantly during the COVID-19 pandemic and colorectal cancer screening was no exception. While the number of people getting colorectal cancer screening will likely rise with increasing numbers of people receiving full vaccination for COVID-19, there are still significant screening gaps, according to Syam Reddy, MD, the Clinical Chairman at UChicago Medicine Ingalls Memorial Hospital.

In a new video interview, Dr. Reddy said the use of computed tomography (CT) colonography can provide an array of benefits in the realm of colorectal cancer screening.

Dr. Reddy said CT colonography provides better detection of cancerous and pre-cancerous lesions than other non-invasive testing measures such as stool testing, He noted CT colonography has comparable detection rates to conventional colonoscopy but offers patients the practical benefits of no sedation and milder preparation prior to the procedure.

Researchers have also demonstrated that preoperative use of CT colonography changed surgical management in over 20 percent of patients with occlusive colorectal cancer, which Dr. Reddy pointed out during a recent lecture on CT colonography at the Society of Abdominal Radiology (SARS) meeting.

Dr. Reddy also noted that CT colonography enables clinicians to perform simultaneous screening for osteoporosis and non-alcoholic fatty liver disease (NAFLD).
