Thursday, April 15, 2004The virtual method detected 55% of patients with at least one suspicious polyp at least 10 millimeters in diameter, compared with a 100% success rate for traditional colonoscopy. For smaller tumors, at least 6 millimeters in diameter, the results were worse: 39% for virtual colonoscopy versus 99% for the traditional method. Eight patients ultimately were diagnosed with cancer; virtual colonoscopy missed the disease in two of them. That's a good summation of the study. The difference between this study and the previous one that hailed the procedure as just as effective as regular colonoscopy, is that this one looked at the procedure as it was performed across several hospitals. Like any radiological procedure, the results are only as good as the person who interprets them. posted by Sydney on 4/15/2004 09:21:00 AM 0 comments 0 Comments: |
