Emerging Perspectives on Computed Tomography Colonography
In recent video interviews, Syam Reddy, MD, Judy Yee, MD and Anand Narayan, MD, discussed various benefits of computed tomography colonography (CTC) for colorectal cancer screening, the underutilization of the CTC procedure and steps moving forward to improve access to this procedure.
Despite a number of practical benefits for patients and having comparable detection rates to conventional colonoscopy for colorectal cancer, computed tomography colonography (CTC) remains significantly underutilized. In fact, a recently published survey of over 13,700 people between the ages of 50 to 75 found that only 1.4 percent of respondents had CTC for colorectal cancer screening.
Various authors have pointed to the lack of Medicare coverage as a key factor in the limited access and use of CTC. Noting the potential impact CTC could have in improving colorectal cancer screening rates in at-risk populations, the American College of Radiology recently wrote a formal request to the Centers for Medicare and Medicaid Services (CMS), urging the organization to reconsider non-coverage of CTC for Medicare and Medicaid beneficiaries.
With this in mind, Syam Reddy, MD, Judy Yee, MD and Anand Narayan, MD, recently spoke with Diagnostic Imaging to discuss the benefits of CTC, limitations of access to the procedure and suggested steps for potentially resolving this issue.

Can CT-Based Deep Learning Bolster Prognostic Assessments of Ground-Glass Nodules?
June 19th 2025Emerging research shows that a multiple time-series deep learning model assessment of CT images provides 20 percent higher sensitivity than a delta radiomic model and 56 percent higher sensitivity than a clinical model for prognostic evaluation of ground-glass nodules.
