Value of MRI imaging in differential diagnosis of hepatocirrhosis regenerated nodules and small hepatocellular carcinoma
肝硬化再生结节与小肝癌患者鉴别诊断中的MRI影像学价值研究

摘要

目的 在肝硬化再生结节与小肝癌鉴别诊断中，分析MRI扫描的临床价值。方法 选取83例肝硬化患者，收治时间2020年5月-2021年12月。均在手术前接受MRI检查，影像学资料完整，以手术病理结果作为金标准，评价MRI在肝硬化再生结节与小肝癌鉴别诊断中的价值。结果 本组83例肝硬化患者的病理学检查结果为：肝硬化再生结节30例，小肝癌53例。MRI诊断结果为肝硬化再生结节33例，小肝癌50例。以病理学检查为金标准，MRI鉴别诊断肝硬化再生结节与小肝癌的敏感度93.33%，特异度90.57%，准确度91.57%。结论 在肝硬化再生结节与小肝癌的鉴别诊断中，MRI具有较高的敏感度、特异度以及准确度，可为病人制定有效的治疗方案提供可靠依据，临床实践中应广泛应用。

Abstract

Objective To analyze the clinical value of MRI scanning in the differential diagnosis of liver cirrhosis regenerated nodules and small liver cancer.
Methods: 83 patients with cirrhosis were selected from May 2020 to December 2021. All patients underwent MRI examination before surgery, and the imaging data were complete. The value of MRI in differential diagnosis of cirrhotic nodules and small hepatocellular carcinoma was evaluated by using the surgical pathological results as the gold standard.
Results: Pathological examination results of 83 patients with liver cirrhosis were as follows: 30 cases of liver cirrhosis regenerated nodules, 53 cases of small liver cancer. MRI diagnosis showed that 33 cases were cirrhotic nodules and 50 cases were small hepatocellular carcinoma. Using pathological examination as the gold standard, THE sensitivity, specificity and accuracy of MRI in differentiating liver cirrhosis nodules from small liver cancer were 93.33%, 90.57% and 91.57% respectively.
Conclusion  : MRI has high sensitivity, specificity and accuracy in the differential diagnosis of liver cirrhosis regenerated nodules and small liver cancer, which can provide reliable basis for patients to formulate effective treatment plan, and should be widely used in clinical practice.
