CAD becomes a spell-check for small polyps March 6, 2015 -- Computer-aided detection (CAD) can only enhance performance if used correctly, and it does not reduce the need for training, according to a presentation on Friday at ECR 2015 in Vienna. CAD for colonography has shown promise, but radiologists need to understand sensitivity and specificity issues, as well as when CAD should be deployed.

Italian men shun flexible sigmoidoscopy for CTC March 5, 2015 -- VIENNA - Whether it's fear of endoscopes or love of high technology, Italian men appear more willing to undergo CT colonography (CTC) than flexible sigmoidoscopy, according to the results of a late-breaking trial presented at ECR 2015.
CAD for virtual monochromatic CTC images shows high accuracy January 6, 2015 -- A computer-aided detection (CAD) algorithm analyzed virtual monochromatic dual-energy CT colonography (CTC) images accurately with few false positives in a study from Massachusetts General Hospital. The researchers believe the study could pave the way to more accurate minimal-prep CTC.
Survey: Patients unfazed by false positives on CTC exams September 24, 2014 -- In a new survey, patients said they believe the benefits of having a malignancy detected on colon screening exams more than outweigh the drawbacks of a false positive, even if it would lead to unnecessary imaging or invasive follow-up, according to an article published in the October issue of Radiology.
ACR cries foul as DNA test beats CTC to Medicare approval August 28, 2014 -- The American College of Radiology (ACR) is crying foul after the U.S. Centers for Medicare and Medicaid Services recently approved a stool DNA test for colorectal cancer screening -- as reimbursement for CT colonography (CTC) continues to languish.
JAMA IM: Older high-risk patients still getting cancer screenings August 20, 2014 -- A substantial number of patients 65 years or older with limited life expectancy still receive routine screenings for cancer, despite the fact that they are unlikely to benefit from treatment procedures, according to a study published online August 18 in JAMA Internal Medicine.
Doctor bonuses do not boost screening compliance July 15, 2014 -- The Canadian province of Ontario spent almost $110 million ($102 million U.S.) on bonuses intended to motivate family physicians to screen more of their patients for breast, cervical, and colorectal cancer, but the program didn't translate into improved screening rates, according to a new study in the Annals of Family Medicine.
ARRS: Even rads prefer optical colonoscopy over CTC May 8, 2014 -- SAN DIEGO - Despite the less invasive nature of CT colonography (CTC), even radiologists would pick optical colonoscopy for themselves, according to research presented at the American Roentgen Ray Society (ARRS) annual meeting.
ARRS: CTC extracolonic findings rare, but often malignant May 7, 2014 -- SAN DIEGO - Even though only a small percentage of patients undergoing screening CT colonography (CTC) for the first time have significant extracolonic findings, most of these will require surgical or medical intervention, according to research presented at the American Roentgen Ray Society (ARRS) meeting.
USPSTF seeks comments on colon screening plan January 10, 2014 -- In a move that could eventually lead to Medicare reimbursement for virtual colonoscopy screening, the U.S. Preventive Services Task Force (USPSTF) on Thursday opened to public commentary a draft research plan for colorectal cancer screening.
