摘要 目的:本研究旨在深入探讨磁共振成像(MRI)在鉴别诊断肝硬化再生结节和小肝癌中的作用。方法:选取2021年1月~2023年7月于本院收治的111例肝硬化患者作为观察对象,参照病理学诊断结果为金标准,均予以所有患者进行CT、MRI检查,分析不同影像学技术在鉴别诊断结节和癌肿中的应用价值。结果:病理学确诊51例肝硬化再生结节和60例小肝癌,CT检出肝硬化再生结节和小肝癌分别为41例、70例;MRI检出肝硬化再生结节和小肝癌分别为49例、62例。计算不同检查方法诊断小肝癌的效能,MRI诊断灵敏度、特异度、准确度分别为98.33%、94.12%、96.40%,均高于CT检查的88.33%、66.67%、78.38%,差异存在统计学意义(P<0.05);经过统计分析,发现小肝癌造影剂峰值时间、肝脏动脉灌注指数与肝硬化再生结节之间存在明显差异(P<0.05)。结论:MRI用于鉴别诊断肝硬化再生结节和小肝癌有较高应用价值,有利于降低误诊、漏诊风险,为临床治疗方案制定和预后评估具有重要意义。 Objective:The purpose of this study is to investigate the effect of magnetic resonance imaging(MRI)in the differential diagnosis of cirrhosis regenerative nodules and small liver cancer.Methods:A total of 111 patients with cirrhosis admitted to our hospital from January 2021 to July 2023 were selected as observation objects,and all patients were referred to the gold standard,underwent CT and MRI examinations,and analyzed the application value of different imaging techniques in the differential diagnosis of nodules and tumors.Results:According to the pathological examination report,there were 51 cases of regenerative nodules and 60 cases of small liver cancer,41 and 70 cases of small liver cirrhosis nodules detected by CT;MRI detected 49 cases of regenerative nodules in cirrhosis and 62 cases of small liver cancer,respectively.According calculating the efficacy of different examination methods,the diagnostic sensitivity,specificity and accuracy of MRI were 98.33%,94.12%and 96.40%,respectively,which were higher than 88.33%,66.67%and 78.38%by CT,statistically significant(P<0.05);Contrast peak time and liver arterial perfusion index were significantly different(P<0.05).Conclusion:MRI has high application value in the differential diagnosis of hardened regenerative nodules and small liver cancer,which is conducive to reducing the risk of misdiagnosis and missed diagnosis,and is of great significance for the formulation of clinical treatment plan and prognosis evaluation.
