Virtual colonoscopy for colorectal cancer screening: current status
نویسندگان
چکیده
Computed tomography colonography (CTC) (also known as 'virtual colonoscopy') is a noninvasive method of imaging the colon using helical CT. Although CTC has been shown to be useful for certain clinical indications, it has not yet been endorsed as a colorectal cancer screening test. The purpose of this article is to review the current status of CTC for colorectal cancer screening. CTC is an accurate method to detect colonic polyps and to select patients who would benefit from colonoscopy. The major advantages of CTC over conventional colonography include its relatively low risk and greater tolerance by patients. In this article, the CTC procedure and results of clinical trials are reviewed, as well as potential pitfalls related to CTC performance and interpretation. Finally, radiation dose, the discovery of incidental extracolonic findings with CTC, bowel preparation methods, and computer-aided diagnosis are addressed.

Colorectal cancer (CRC) is one of the leading cancers in the world and early-screening is still the best method of cancer patient survival. However, colonoscopy as the current gold standard is not without flaws and an emerging technique called surface-enhanced Raman spectroscopy (SERS) coupled with machine learning is a possible candidate that could be applied in parallel with colonoscopy. This...

BACKGROUND Colorectal cancer is a major cause of cancer mortality and morbidity. Screening can potentially prevent most colorectal cancers by detection and removal of precursor adenomas. METHODS The literature and clinical practice guidelines are reviewed, with an emphasis on advances of the last 10 years and evolving screening methods. RESULTS Colonoscopy has come to be used for screening ...

Background While colorectal cancer (CRC) is one of the most preventable causes of cancer mortality, it is one of the leading causes of cancer death in Canada where CRC screening uptake is suboptimal. Given the increased rate of mortality and morbidity among mental health patients, their condition could be a potential barrier to CRC screening due to greater difficulties in adhering to behaviours...
