VC not cost-effective in FOBT-positive screening population
By Eric Barnes
Patients with positive screening results on fecal occult blood tests (FOBTs) should probably head straight to optical colonoscopy for their next exam, according to a new study from the Netherlands. Virtual colonoscopy may not be cost-effective in this population because so many FOBT-positive patients would need referral for polypectomy anyway, the researchers said.

If virtual colonoscopy is to function effectively as a screening tool, it must not only deliver consistently high sensitivity for clinically relevant lesions, but also show a low number of false positives and a high degree of concordance with optical colonoscopy. Fortunately, VC appears to be keeping its end of the bargain, according to new research.
