探讨CT及MRI影像学检查对原发性肝癌患者微血管浸润诊断价值的研究

Diagnostic Value of CT and MRI Imaging on Microvascular Infiltration in Patients with Primary Liver Cancer

目的:探讨针对原发性肝癌,CT、MRI影像学检查对患者的诊断价值。方法:选取2016年5月—2020年5月南通市中医院收治的147例原发性肝癌患者作为研究对象,按照是否存在微血管浸润分为观察组(73例)和对照组(74例),两组患者均行CT、MRI检查,比较两组患者CT及MRI征象、CT及MRI影像学特征。结果:与对照组比较,观察组的门脉分支癌栓数量、瘤内动脉和低密度/信号环征象、局部包膜不完整、边缘模糊,差异有统计学意义(t=11.145、3.178、14.837、56.712,P<0.05);两组患者弥散系数,差异无统计学意义(χ2=1.245,P>0.05),CT与MRI检查的诊断结果比较差异无统计学意义(χ2=2.580、6.134、5.297、3.426、4.377,P>0.05)。结论:采用CT、MRI检查原发性肝癌患者,结果表明边缘模糊征象、瘤内动脉和低密度/信号环征象、门脉分支癌栓具有明确的诊断价值。

Objective:To investigate the diagnostic value of CT and MRI imaging in patients with primary liver cancer.Methods:147 patients with primary liver cancer admitted to the hospital from May 2016 to May 2020 were selected as study sub⁃jects and divided into observation group(73 cases)and control group(74 cases)according to the presence or absence of microvascu⁃lar infiltration.CT and MRI examinations were performed in both groups,and CT and MRI signs,CT and MRI imaging features were compared between the two groups.Results:Compared with the control group,there were statistically significant differences in the number of portal branch cancer thrombi,intra-arterial and hypodense/signal ring signs,local incomplete envelope,and blurred margins in the observation group(t=11.145,3.178,14.837,56.712,P<0.05)The difference in diffusion coefficients between the two groups was not statistically significant(χ2=1.245,P>0.05).The differences in diagnostic findings between CT and MRI exami⁃nations were not statistically significant(χ2=2.580,6.134,5.297,3.426,4.377,P>0.05).Conclusion:Patients with primary hepato⁃cellular carcinoma were examined using CT and MRI,and the results showed that blurred margin signs,intratumoral arterial and hypodense/signal ring signs,and portal branch carcinoma thrombi had clear diagnostic value.
