The importance of CAD and DECT in CT colonography

IntroductionAccording to the American College of Radiology and Cancer Society, CTC has been recognized as a valuable screening method for detecting CRC in people at medium risk an alternative endoscopic colonoscopy. The condition proper interpretation this procedure is patient’s preparation examination. evaluation test includes: topogram, transverse images (as reference images), multifaceted reconstructions three-dimensional (3D navigator). Materials methods literature on use diagnosis was analyzed. A review scientific indexed PUBMED database from last 10 years carried out. Results introduction dual energy computed tomography (DECT) clearly improved diagnostic accuracy CTC. main advantage DECT possibility obtaining iodine maps VNC (virtual non-contrast) – ’’virtual’’ native image (without contrast). allows you monitor results extent capture map images, respectively, without using pre-recorded tomographic images. Pilot tests showed that effective tool CT colonography diagnostics electronic colon loop cleaning after barium labeling. Computer Aided Diagnosis (CAD) algorithm high helps detection intestinal tumors. ConclusionsThe development modern technologies used proves it safe acceptable technique patients. Lack invasiveness, low radiation dose efficiency may encourage more undergo colorectal cancer future.
