Nineteen cases of proven hepatic alveolar echinococcosis were examined by magnetic resonance (MR) and the results were compared with CT. Fibrous and parasitic tissue showed low signal both on T1- and, generally, on T2-weighted images. In a few cases a high signal on T2-weighted images may be observed, due either to central necrotic zones or to small peripheral cysts. Central necrosis was more easily identified by MR than by CT. However, MR seemed to be less effective than CT in allowing us to reach a positive diagnosis, due to its inability to show microcalcifications. In addition, MR may not reveal small lesions. In most cases T1-weighted images revealed more clearly than CT did the margins of the lesions and the hepatic extension, especially to hepatic veins, vena cava, and perihepatic spaces.
对19例经证实的肝泡型包虫病患者进行了磁共振成像（MR）检查，并将结果与CT检查结果进行了比较。纤维组织和寄生组织在T1加权图像和通常在T2加权图像上均显示低信号。在少数情况下，由于中央坏死区或小的周边囊肿，在T2加权图像上可能会观察到高信号。MR比CT更容易识别中央坏死。然而，由于MR无法显示微钙化，在做出阳性诊断方面似乎不如CT有效。此外，MR可能无法显示小病变。在大多数情况下，T1加权图像比CT更清楚地显示病变的边缘和肝脏的延伸，特别是向肝静脉、腔静脉和肝周间隙的延伸。
