Consequences of CT colonography in stenosing colorectal cancer

CT colonography in early detection of colorectal cancer

Colorectal cancer is the third most common cancer worldwide and the fourth leading cause of cancer death. In the United States it occupies the second place: only lung cancer claims more lives. The prevalence of colorectal cancer amounts to about 1 million in the United States alone [1]. The American Cancer Society estimates that about 112,340 new cases of colon cancer and 41,420 new cases of re...

CT colonography and colorectal screening.

CT colonography in detection of colorectal carcinoma

BACKGROUND Diagnostic methods used in screening and detecting colorectal carcinoma are digitorectal examination, faecal occult blood testing, sigmoidoscopy, DNA stool analysis, barium enema, colonoscopy, and as of recently CT colonography. The aim of this study was to establish diagnostic accuracy and comfort of CT colonography compared to colonoscopy and barium enema. PATIENTS AND METHODS We...

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...
