Virtual colonoscopy has been around for a long time already and since the beginning the clinical value was debated. A recent publication in Radiology suggests that it can be used as a primary screening tool for colorectal cancer in adults over the age of 65. There was no significant difference in the accuracy of CT colonography for the detection of large and intermediate-sized adenomatous lesions in participants aged 65 years or older compared with that in younger participants; per-participant sensitivity and specificity among the older and younger cohorts were 0.82 and 0.83 and 0.92 and 0.86, respectively.
