摘要目的评价MR弹性成像对于慢性乙型肝炎(CHB)与其他病因肝纤维化分期的诊断效能。材料与方法本回顾性研究经伦理审查委员会批准,免除知情同意书。对352例慢性肝病病人(281例CHB、71例非CHB)、肝细胞肝癌病人及64例活体供肝者行术前MR弹性成像。在MR弹性成像剪切硬度定量图上测量肝脏硬度(LS)值,采用ROC
Abstract Objective To evaluate the diagnostic efficacy of MR elastography in the diagnosis of chronic hepatitis B (CHB) and other stages of hepatic fibrosis. Materials and Methods This retrospective study was approved by the ethics review board and informed consent was waived. Preoperative MR elastography was performed on 352 patients with chronic liver disease (281 CHB, 71 non-CHB), hepatocellular carcinoma patients and 64 live donor liver donors. Liver stiffness (LS) values were measured on a MR elastography shear stiffness quantification chart using ROC
