计算机辅助检测在CT结肠成像中的应用

Application of computer-aided detection in CT colonography

CT结肠成像(CTC)已广泛应用于结肠疾病的诊断。计算机辅助检测(CAD),可自动检测可疑病变,供读片者进一步诊断,提高放射科医生对肿块的检出能力,并降低不同读片者间诊断能力的差异。本文对CAD的原理、对结肠疾病的诊断价值、局限性、面临的挑战和未来发展趋势予以综述。

CT colonography（CTC）has been widely used in diagnosis of colon diseases.Computer-aided detection（CAD）automatically detects the locations of suspicious lesions on CTC,and provides radiologists with a second opinion.CAD has the potential to increase radiologists＇ diagnostic performance in the detection of lesions and to decrease variability of the diagnostic accuracy among readers.The current fundamental scheme,the key techniques used for detection of lesions on CTC,the detection performance,as well as the pitfalls,challenges,and the future of CAD were reviewed in this article.
