摘要: 目的 探讨多层螺旋计算机断层扫描(MSCT)联合增强磁共振成像(MRI)鉴别诊断肝脏局灶性结节性增生(FNH)与肝细胞癌(HCC)的价值。方法 2016年1月~2024年8月我院收治的108例肝脏占位性病变患者,均接受MSCT和增强MRI扫描检查。结果 经病理学检查,本组诊断FNH患者41例,病灶直径为(3.3±0.9)cm,和HCC患者67例,病灶直径为(2.9±0.9)cm; HCC组病灶MR动脉增强分数(AEF)和病灶/肝组织AEF比值分别为(67.7±7.6)和(1.4±0.2),显著高于FNH病灶【分别为(53.7±4.5)和(1.2±0.1),P<0.05】;HCC病灶T1WI呈低信号占比为83.6%,显著高于FNH病灶的58.5%(P<0.05),ADC呈低信号占比为94.0%,显著高于FNH病灶的14.6%(P<0.05),强化呈快进快出占比为91.0%,显著高于FNH病灶的2.4%(P<0.05);HCC病灶相对ADC值为(0.8±0.2),显著低于FNH病灶【(1.1±0.2),P<0.05】。结论 MSCT联合增强MRI可鉴别诊断FNH与HCC,可帮助临床医生做出初步判断。

Abstract: Objective The aim of this study was to investigate imaging feature of multi-slice spiral computed tomography (MSCT) and enhanced magnetic resonance imaging (MRI) in the differential diagnosis of focal nodular hyperplasia (FNH) of liver and hepatocellular carcinoma (HCC). Methods A total of 108 patients with intrahepatic space-occupying lesions (SOL) were encountered in our hospital between January 2016 and August 2024, and all underwent dual-source force 256-slice spiral CT and enhanced MAGNETOM Spectra 3.0 T MRI scans. Results Of 108 patients with SOL in our series, the histo-pathological examination proved FNH in 41 cases, with lesion diameter of (3.3±0.9)cm, and HCC in 67 cases, with diameter of (2.9±0.9)cm; MR arterial enhancement fractional (AEF) and lesion/liver AEF ratio in HCC were (67.7±7.6) and (1.4±0.2), both significantly higher than [(53.7±4.5) and (1.2±0.1), respectively, P<0.05] in FNH; percentage of low signals on T1WI in HCC was 83.6%, much higher than 58.5%(P<0.05), percentage of low signals on apparent diffusion coefficient (ADC) was 94.0%, much higher than 14.6%(P<0.05), and percentage of fast in and fast out style of enhancement was 91.0%, much higher than 2.4%(P<0.05) in FNH; relative ADC in HCC was (0.8±0.2), much lower than [(1.1±0.2), P<0.05] in FNH. Conclusion Features of MSCT and enhanced MRI could help clinicians make differential diagnosis of FNH from HCC, which might be very important in clinical practice.
