Diagnostic value of CT and MRI imaging manifestations for microvascular invasion in primary hepatocellular carcinoma

:681-688
 
       目的   探讨CT、MRI影像学表现对原发性肝细胞癌(HCC)微血管侵犯(MVI)的诊断价值。方法   选取2018年1月—2024年7月江门市第二人民医院(江门市中心医院蓬江分院)和江门市中心医院120例(共158个病灶)HCC患者,均行上腹部CT、MRI平扫+增强及弥散加权成像(DWI)检查;以术后病理结果为金标准。比较CT、MRI平扫+增强及DWI对HCC MVI诊断效能;分析HCC MVI诊断中CT、MRI平扫+增强及DWI检查与术后病理确诊结果之间的一致性;比较HCC MVI与无HCC MVI患者影像学表现及表观扩散系数(ADC)值。结果    DWI检查对HCC MVI的诊断效能(灵敏度、特异度、准确度、阳性预测值、阴性预测值)均显著性高于CT、MRI平扫+增强(P<0.05);CT、MRI、DWI对原发性肝细胞癌患者微血管侵犯的诊断效能比较,差异均无统计学意义(P>0.05)。在HCC MVI诊断效能中,CT、MRI影像学表现与术后病理确诊结果之间为中度一致性;DWI与术后病理确诊结果之间为高度一致性。HCC MVI患者的强化方式在非边缘动脉期强化、强化包膜、晕状强化、结中结、门脉分支癌栓占比均显著性高于无HCC MVI患者(P<0.05)。在不同b值(400、800、1 000、1 500 s/mm2 )下,HCC MVI患者的ADC值均显著性高于无HCC MVI患者(P<0.05)。结论    CT、MRI平扫+增强及DWI对HCC MVI均具有较好的诊断效能,而MRI诊断结果与病理诊断一致性更佳,尤其DWI图中ADC值可更加精准地判断HCC的患者是否发生微血管侵犯,有助于指导临床医生建立“个体化”精准诊疗策略。
       Objective  To explore the diagnostic value of CT and MRI imaging manifestations for microvascular invasion(MVI)in primary hepatocellular carcinoma(HCC).Methods  A total of 120 patients(158 lesions in total)with HCC in the Second People’s Hospital of Jiangmen(Pengjiang Branch of Jiangmen Central Hospital)and Jiangmen Central Hospital were selected from January 2018 to July 2024,all underwent CT and MRI plain + enhanced and diffusion-weighted imaging(DWI)of the upper abdomen;postoperative pathology results was used as the diagnostic gold standard.The diagnostic efficacy of CT,MRI plain + enhanced and DWI for HCC MVI was compared.The concordance among CT,MRI plain + enhanced and DWI examinations with postoperative pathological diagnostic findings in the diagnosis of HCC MVI.Imaging manifestations and apparent diffusion coefficient(ADC)values in patients with and without HCC MVI were compared.Results  Diagnostic effectiveness of DWI examination for HCC MVI(sensitivity,specificity,accuracy,positive predictive value,negative predictive value)were all significantly higher than those of CT and MRI plain + enhanced(P<0.05);none of the differences were statistically significant(P>0.05)in the comparison of diagnostic effectiveness of CT,MRI,and DWI for the diagnosis of MVI in patients with primary HCC.In HCC MVI diagnostic effectiveness,moderate concordance was found among CT,MRI imaging phenotypes and postoperative pathology results;high concordance was found between DWI and postoperative pathology results.In HCC MVI patients,the proportion of non-marginal arterial reinforcement,enhanced envelope,halo reinforcement,nodal in nodal and portal branch cancer thrombi was significantly higher than that in patients without HCC MVI(P<0.05).At different b-values(400,800,1 000,1 500 s/mm2 ),ADC values were all significantly higher in patients with HCC MVI than in patients without HCC MVI(P<0.05).Conclusions  CT,MRI plain + enhanced and DWI have good diagnostic effectiveness for HCC MVI,while MRI diagnostic results are in better concordance with pathologic diagnosis.In particular,ADC values in DWI maps can more accurately determine whether MVI occurs in patients with HCC,which helps to guide clinicians to establish“individualized”and precise diagnosis and treatment strategies.
