Setup of computer-aided diagnosis system for prostate cancer on multiparametric MRI

多参数磁共振成像(multiparametric MRI，mpMRI)已成为前列腺癌检出、分期、指导活检及治疗后随访最常用的影像学方法。由于MRI技术的复杂性，诊断具有较强的经验依赖性。计算机辅助诊断(computer-aided diagnosis， CAD)技术可进行多变量分析，提高疾病的临床诊断效能，近年来广泛应用于医学图像分析。基于mpMRI的前列腺癌CAD系统近几年取得了较大进展并显现出良好的应用前景，本文结合本单位实际经验，简要介绍CAD在前列腺癌mpMRI诊断中的进展。Multiparametric MRI (mpMRI) has been considered as the method of choice for prostate cancer detection, staging, guidance for biopsy and treatment follow-up. However, effectiveness of mpMRI is usually affected by personal experience and expertise. Computer-aided diagnosis (CAD) system shows promise for improved prostate cancer diagnosis. This article aims to review the technique advance and effectiveness comparison of the state-of-the-art CADs for prostate cancer on mpMRI.中国科技核心期刊(ISTIC)2117-1222
