CT colonography and colorectal screening.

Advances in CT Colonography for Colorectal Cancer Screening and Diagnosis

CT colonography (CTC) is a validated colorectal cancer test that provides an additional minimally-invasive screening option which is likely to be preferred by some patients. Important examination prerequisites include adequate colonic cleansing and distention. Tagging of residual material aids in the differentiation of true polyps from stool. Low radiation dose technique should be employed rout...

CT colonography: A new technique for colorectal cancer screening

Although optical col on oscopy is the criterion standard for colorectal cancer screening, CT colonography is now accepted to be useful when screening averagerisk patients. Earlier studies that indicated poor sensitivity for CT colonography have now been largely refuted. Recent improvements in workstation design and advances that permit primary 3D viewing of images have increas ed screening accu...

Computed tomography colonography for colorectal cancer screening.

Colorectal cancer screening has been shown to help prevent cancer-related death. Concerns about suboptimal adherence to conventional colonoscopy has led to the search for alternative screening modalities. Computed tomography colono-graphy (CTC) is a highly sensitive and minimally invasive alternative modality. The American College of Radiology has established a standardized reporting system for...

Study protocol: population screening for colorectal cancer by colonoscopy or CT colonography: a randomized controlled trial

BACKGROUND Colorectal cancer (CRC) is the second most prevalent type of cancer in Europe. Early detection and removal of CRC or its precursor lesions by population screening can reduce mortality. Colonoscopy and computed tomography colonography (CT colonography) are highly accurate exams and screening options that examine the entire colon. The success of screening depends on the participation r...
