前列腺影像报告及数据系统V2的构建及在前列腺癌多参数MRI诊断中的初步评价

Structure and preliminary evaluation of Prostate Imaging Reporting and Data System V2 in diagnosis of prostate cancer using multi-parametric MRI

前列腺癌发病率居老年男性恶性肿瘤第2位。多参数MRI(multi-parametric MRI,Mp-MRI)是前列腺癌检出、分期以及选择治疗方案的重要依据。为规范前列腺MRI数据采集、判读和报告,欧洲泌尿生殖放射学会于2012年发布前列腺影像报告及数据系统(Prostate Imaging Reporting and Data System,PI-RADS)。由于在应用过程中存在一定的局限性,美国放射学会、欧洲放射学会等组成的联合委员会于2014年发布了新版本PI-PADS V2。近年来学者们围绕其对前列腺癌诊断的有效性、准确性及一致性等方面展开了一些研究。该文对PI-RADS V2构建及在前列腺癌Mp-MRI诊断中的初步评价进行了综述。

The incidence of prostate cancer ranks the second in malignant tumors among elderly males. Multi parametric MRI （Mp-MRI） is an important mean for detection, staging, and grading of prostate cancer. In order to standardize the collection, interpretation, and reporting of prostate MRI data, the European Urogenital Radiology Society launched the Prostate Imaging Reporting and Data System （PI-RADS） in 2012. Due to some limitations in the application process, the Joint Committee of the American Society of Radiology and the European Society of Radiology issued an updated version of PI-PADS V2 in 2014. In recent years, some studies have been carried out on the effectiveness, accuracy, and consistency of the diagnosis of prostate cancer. This article will review the application and research status of PI-RADS V2 system in the diagnosis of Mp-MRI for prostate cancer.
