Clinical efficacy and accuracy analysis of CT and MR imaging examination in the diagnosis of hepatocellular carcinoma
CT与MR影像学检查诊断肝细胞癌的临床效果及准确性分析

摘要

目的 分析CT与MR影像学检查在肝细胞癌诊断中的临床效果及准确性。方法 运用回顾性分析的方法，对我院在2023年10月至2024年10月期间收治的肝细胞癌患者展开调查。经过严格筛选，最终确定了50例符合条件的患者纳入研究范围。在研究过程中，这50例患者均接受了磁共振成像（MR）检查以及计算机断层扫描（CT）检查。为了准确评估两种检查方式对于肝细胞癌的诊断价值，将病理诊断结果设定为金标准。通过对两种检查方式所获得的诊断结果进行详细比对，深入分析各自的诊断效能。结果 在对肝细胞癌的诊断中，MR诊断在敏感度方面表现突出，相较于CT诊断，对疾病的检测能力更强。在特异度方面，MR诊断也展现出了明显的优势。准确度上，MR诊断同样更为出色，其诊断结果与实际病情的符合程度更高。在阳性预测值、阴性预测值方面，MR诊断均优于CT诊断（P＜0.05）。结论 MR影像学检查在肝细胞癌的诊断中具有不可替代的重要作用，可被优先考虑作为肝细胞癌诊断的影像学检查方法。

Abstract

Objective To analyze the clinical efficacy and accuracy of CT and MR imaging examinations in the diagnosis of hepatocellular carcinoma.
Methods Using the method of retrospective analysis, we investigated the patients with hepatocellular carcinoma admitted to our hospital from October 2023 to October 2024. After rigorous screening, 50 eligible patients were finally identified for inclusion in the scope of the study. During the course of the study, all 50 patients underwent magnetic resonance imaging (MR) and computed tomography (CT). In order to accurately evaluate the diagnostic value of the two examination methods for hepatocellular carcinoma, the pathological diagnosis results were set as the gold standard. The diagnostic results obtained by the two examinations are compared in detail, and the diagnostic performance of each is analyzed in depth.
Results In the diagnosis of hepatocellular carcinoma, MR diagnosis has outstanding sensitivity and has stronger detection ability than CT diagnosis. In terms of specificity, MR diagnosis has also shown significant advantages. In terms of accuracy, MR diagnosis is also better, and its diagnosis is more consistent with the actual condition. In terms of positive predictive value and negative predictive value, MR diagnosis was better than CT diagnosis (P<0.05).
Conclusion   MR imaging has an irreplaceable and important role in the diagnosis of hepatocellular carcinoma, and can be prioritized as an imaging examination method for the diagnosis of hepatocellular carcinoma.
