背景目前随着医学影像学的发展,术中超声(IOUS)的作用受到质疑。本研究的目的是比较IOUS、多层CT和MRI在肝肿瘤检测准确性中的价值。方法回顾性分析运用8层和64层CT扫描以及单独MRI扫描或MRI联合CT扫描的418例患者。以病理诊断结果为基准。结果以病理检出的肿瘤数目作为基准,8层CT、64层CT、MRI和IOUS的检出符合率分别为0.627、0.785、0.657和0.913。以病理检查结果为基准,IOUS的检查符合率为0.871,明显高于8
Background With the development of medical imaging, the role of intraoperative ultrasound (IOUS) has been questioned. The purpose of this study was to compare the value of IOUS, multi-slice CT and MRI in the accuracy of liver tumor detection. Methods Retrospective analysis of 418 patients with 8-slice and 64-slice CT scan and MRI alone or combined with CT scan. The pathological diagnosis as a benchmark. Results Based on the number of pathologically detected tumors, the coincidence rates of 8-slice CT, 64-slice CT, MRI and IOUS were 0.627, 0.785, 0.657 and 0.913, respectively. According to the results of pathological examination, the coincidence rate of IOUS examination was 0.871, which was significantly higher than 8
