磁共振与CT评估肝癌患者介入术后肿瘤活性的临床价值对比

Comparison on Clinical Value between Magnetic Resonance Imaging and CT in the Evaluation of Tumor Activity in Liver Cancer Patients after Interventional Surgery

目的比较磁共振与CT评估肝癌患者介入术后肿瘤活性的临床价值。方法选取2019年8月至2021年8月我院行介入栓塞治疗的52例肝癌患者(65个病灶),于介入术后3~5周行磁共振与CT检查。以病理检查结果作为“金标准”,分析磁共振、CT对肝癌患者介入术后肿瘤阳性病灶的诊断效能。结果65个肿瘤病灶中有26个经术后病理检查证实为阳性;磁共振共检出24个阳性病灶,CT共检查出16个阳性病灶;磁共振的灵敏度、准确度分别为84.62%、90.77%,均高于CT的46.15%、72.31%(P<0.05)。κ检验显示,磁共振与病理检查结果的一致性极好(κ=0.805,P=0.000);CT与病理检查结果的一致性差(κ=0.384,P=0.001)。结论与CT相比,磁共振在肝癌患者介入术后肿瘤活性评估中的应用价值更高,可提高肿瘤阳性病灶检出率,为临床治疗提供有效的参考依据。

Objective To compare the clinical value between magnetic resonance imaging and CT in the evaluation of tumor activity in liver cancer patients after interventional surgery.Methods 52 liver cancer patients(65 lesions)with interventional embolization therapy in our hospital from August 2019 to August 2021 were selected and given magnetic resonance imaging and CT at 3 to 5 weeks after the interventional surgery.Taking pathological examination results as the gold standard,the diagnostic efficacy of magnetic resonance imaging and CT for tumor positive lesions in liver cancer patients afer interventional surgery was analyzed.Results Among 65 tumor lesions,26 tumor lesions were confirmed as positive by pathological examination after surgery.A total of 24 positive lesions were detected by magnetic resonance imaging,and 16 positive lesions were detected by CT.The sensitivity and accuracy of magnetic resonance imaging were 84.62%and 90.77%,respectively,higher than 46.15%and 72.31%of CT(P<0.05).k test showed excellent consistency between magnetic resonance imaging and pathological examination results(κ=0.805,P=0.000),and poor consistency between CT and pathological examination results(κ=0.384,P=0.001).Conclusions Compared with CT,magnetic resonance imaging has higher application value in the evaluation of tumor activity in liver cancer patients after interventional surgery,which can improve the detection rate of tumor positive lesions and provide effective reference for clinical treatment.
