According to the report, the Maryland-based research team, led by Patrick Young, MD, had three board-certified gastroenterologists and four GI fellows interpret an average of 45 CT colonoscopy images. Each reader underwent training with an experienced CT colonography radiologist.
The researchers found that the gastroenterologists had an average sensitivity and specificity for finding 6-mm polyps of 84 percent and 79 percent, respectively, according to the report. For 8-mm polyps, average sensitivity and specificity was 84 percent and 74 percent, and 88 percent and 85 percent for 10-mm polyps.
According to the report, 83 percent of the gastroenterologists scored 0.6 and 66 percent 0.9, meaning they were in good agreement with radiologists’ findings. The average reading time for the gastroenterologists was 18 minutes.
