摘要目的确定活检证实的中度到重度肝脏脂肪变性(组织学≥30%)CT平扫特异性高的肝脏衰减值阈值。方法315例无症状成人[男207例,女108例;平均(31.5±10.1)岁]在同一天接受了CT平扫与超声引导下的肝脏活检。在不知活检结果的情况下,采用标准感兴趣区法测量肝脏的CT衰减值。采用
Abstract Objective To determine the threshold value of hepatic attenuation value of biopsy-proven CT scan with moderate to severe hepatic steatosis (histology≥30%). Methods 315 asymptomatic adults [207 men and 108 women (mean, 31.5 ± 10.1) years] underwent CT scan and ultrasound-guided liver biopsy on the same day. In the absence of biopsy results, the standard region of interest method was used to measure liver CT attenuation values. use
