With a retrospective analysis of images from 39 patients with histologically proven liver tumours we tried to determine the best MRT-parameter for detection of cavernous hemangioma (n = 19) and its differentiation from malignoma (metastases n = 17, HCC n = 5). The best differentiation was achieved with the contrast-to-noise ratio between lesion and liver in multi-echo-images with TR/TE = 2,000/210 ms and a definite limit with an accuracy of 84% for hemangioma and 91% for malignoma. The respective intensity ratios (lesion/liver) were 95% and 77%. T2-relation times and the T1- and T2-ratios were also calculated. In contrary to the literature we think that these parameters are not sufficiently discriminating.
通过对39例经组织学证实的肝肿瘤患者的图像进行回顾性分析，我们试图确定用于检测海绵状血管瘤（n = 19）及其与恶性肿瘤（转移瘤n = 17，肝细胞癌n = 5）鉴别的最佳磁共振成像（MRT）参数。在TR/TE = 2000/210 ms的多回波图像中，通过病变与肝脏之间的对比噪声比实现了最佳鉴别，对于血管瘤和恶性肿瘤有明确的界限，准确率分别为84%和91%。各自的强度比（病变/肝脏）分别为95%和77%。还计算了T2相关时间以及T1和T2比值。与文献相反，我们认为这些参数的鉴别能力不足。
