| 目的 比较18F-FDG PET/CT与PET/MR显像对肝脏局灶性病变（FLLs）的临床应用价值。方法 回顾性分析41例FLLs患者的临床资料、18F-FDG全身PET/CT及上腹部MR扫描图像。比较CT、MRI、PET、PET/CT及PET/MR对FLLs的检出率。结果 41例FLLs患者中共检出69个病灶，包括肝脏良性病灶22个、肝细胞癌（HCC）17个、转移瘤30个。CT、MRI、PET、PET/CT及PET/MR对FLLs的总体检出率分别为72.46%（50/69）、94.20%（65/69）、55.07%（38/69）、79.71%（55/69）及100%（69/69）。PET/MR对肝脏良性病灶及HCC的检出率（22/22，100%；17/17，100%）均高于PET/CT（13/22，59.09%；12/17，70.59%；P均<0.05），二者对转移瘤的检出率均为100%（30/30）。结论 PET/MR对FLLs的检出率较高，具有良好的临床应用价值。 |

| Objective To compare the clinical value of 18F-FDG PET/CT and PET/MR in focal liver lesions (FLLs). Methods The data of clinic, 18F-FDG whole-body PET/CT, and upper abdomen MR imaging of 41 patients with FLLs were analyzed retrospectively. The detection rates of CT, MRI, PET, PET/CT and PET/MR were compared. Results In 41 FLLs patients, there were 69 liver lesions, and the number of benign lesions, hepatocellular carcinoma and metastasis was 22, 17 and 30 respectively. The detection rates of CT, MRI, PET, PET/CT and PET/MR were 72.46% (50/69), 94.20% (65/69), 55.07% (38/69), 79.71% (55/69) and 100% (69/69). The detection rate of PET/MR was significantly higher than that of PET/CT on liver benign lesions (100%[22/22] vs 59.09%[13/22]) and hepatocellular carcinoma (100%[17/17] vs 70.59%[12/17], both P<0.05), in addition, the detection rate of PET/MR and PET/CT on liver metastasis were also 100% (30/30). Conclusion PET/MR has high detection rate and clinical value in FLLs. |
