We report the results of magnetic resonance imaging (MRI) of the liver in 46 patients with various previously confirmed focal lesions. A characteristic signal pattern was found in hemangiomas (n = 11), with marked signal hyperintensity on T2 and proton weighted images as compared to normal liver tissue. Cysts (n = 7) also showed marked hyperintensity on T2 images, but could easily be differentiated by a lesser intensity on proton weighted images and signal hypointensity on T1 weighted images. Primary liver tumors (n = 4), metastatic liver disease (n = 18), focal nodular hyperplasia (n = 5), and liver adenoma (n = 1) revealed a weak signal hyperintensity on T2 images, with varying signals in T1 and proton weighted modalities. These data combined with other recent communications in the literature indicate that MRI is a promising diagnostic technique in the detection of focal liver lesions and that it may offer a high degree of specificity in the diagnosis of hepatic hemangiomas and benign cysts.
我们报告了46例先前已确诊的患有各种局灶性病变患者的肝脏磁共振成像（MRI）结果。在血管瘤（n = 11）中发现了一种特征性信号模式，与正常肝组织相比，在T2加权像和质子加权像上有明显的信号高增强。囊肿（n = 7）在T2加权像上也显示出明显的高增强，但通过质子加权像上较低的强度和T1加权像上的信号低增强可以很容易地鉴别出来。原发性肝癌（n = 4）、转移性肝病（n = 18）、局灶性结节性增生（n = 5）和肝腺瘤（n = 1）在T2加权像上显示出微弱的信号高增强，在T1加权像和质子加权像上信号各不相同。这些数据与文献中最近的其他报道相结合表明，MRI是检测肝脏局灶性病变的一种有前景的诊断技术，并且在肝血管瘤和良性囊肿的诊断中可能具有高度特异性。
