Researchers from the U.S. National Institutes of Health (NIH) will introduce their computer-aided detection (CAD) system for identifying renal calculi and lesions on CT colonography (CTC) studies in this RSNA 2013 session.

It can be challenging to detect renal calculi and lesions on CTC images because the modality is used primarily for colon cancer screening. In addition, the studies are usually performed with lower dose and without intravenous contrast, according to presenter Dr. Ronald Summers, PhD, of the NIH.

However, in testing, the NIH's CAD tool had 80% sensitivity for detecting renal calculi at a rate of one false positive per patient, and 87% sensitivity for detecting lesions at a rate of seven false positive per patient. With future clinical validation, the CAD system may contribute to improved diagnosis of renal calculi and lesions on CTC images, according to the researchers.
