The magnetic resonance (MR) examinations of six patients with intrahepatic calculi were reviewed retrospectively to 1) determine the ability of MR to demonstrate intrahepatic calculi and 2) assess the MR appearance of the stones. In five out of six cases, MRI demonstrated intrahepatic calculi. In three cases, stones exhibited a low intensity signal on the different spin echo (SE) sequences, as previously described by in vitro and in vivo studies. However in two other cases, a significant signal with short T1 and relatively long T2 relaxation times was noticed. These different features are discussed in relation to chemical and physical differences in intrahepatic calculi and compared with variable CT attenuation values of stones. MRI seems to provide complementary information concerning intrahepatic calculi.
回顾性分析6例肝内胆管结石患者的磁共振（MR）检查结果，以：1）确定MR显示肝内胆管结石的能力；2）评估结石的MR表现。6例患者中有5例MRI显示肝内胆管结石。3例患者的结石在不同的自旋回波（SE）序列上表现为低强度信号，正如之前体外和体内研究中所描述的那样。然而，在另外2例患者中，发现结石具有短T1和相对长T2弛豫时间的显著信号。针对肝内胆管结石的化学和物理差异对这些不同特征进行了讨论，并与结石不同的CT衰减值进行了比较。MRI似乎能提供有关肝内胆管结石的补充信息。
