The bowel and beyond: extracolonic findings from CT colonography

Extracolonic findings on CT colonography increases yield of colorectal cancer screening.

OBJECTIVE The purpose of this study is to evaluate the impact of extracolonic findings when screening is undertaken by CT colonography (CTC). MATERIALS AND METHODS We performed a retrospective cohort study of patients completing a screening CTC from August 2003 to June 2006 at Walter Reed Army Medical Center. Extracolonic findings were categorized using a CTC reporting and data system that cl...

Extracolonic findings at computed tomography colonography are a challenge.

AIM Our aim was to perform a prospective evaluation of the frequency and diagnostic consequences of extracolonic findings at multidetector array computed tomography colonography (MDCTC) in asymptomatic patients undergoing surveillance for former colorectal polyps or cancer. PATIENTS AND METHODS Seventy five consecutive patients undergoing surveillance for former colorectal cancer (CRC) or lar...

Detection of extracolonic pathologic findings with CT colonography: a discrete choice experiment of perceived benefits versus harms.

PURPOSE To determine the maximum rate of false-positive diagnoses that patients and health care professionals were willing to accept in exchange for detection of extracolonic malignancy by using computed tomographic (CT) colonography for colorectal cancer screening. MATERIALS AND METHODS After obtaining ethical approval and informed consent, 52 patients and 50 health care professionals undert...

CT colonography and colorectal screening.

CT colonography standards.

Computed tomography (CT) colonography is the established successor to the barium enema for the detection of colonic neoplasia due to superior performance and patient experience. Consequently, CT colonography is widely disseminated across Western populations and increasingly provided by both subspecialist and general radiologists alike. As a result, CT colonography is now part of the core traini...
