MRI与CT对肝癌介入术后肿瘤活性的判断价值研究

Study on the Value of MRI and CT in Judging the Tumor Activity After Interventional Surgery for Hepatocellular Carcinoma

目的探讨MRI和CT对肝癌介入术后肿瘤活性的评估价值。方法选取2015年4月-2021年8月本院收治的63例经病理穿刺确诊为肝癌的患者作为研究对象。所有对象均在介入术后行CT、MRI检查,并以数字减影血管造影检查为金标准,比较两种影像学方法对肿瘤活性的评估价值。结果CT活性病灶的检出率低于MRI,组间比较差异有统计学意义(P<0.05)。MRI的准确率和敏感性高于CT,组间比较差异有统计学意义(P<0.05)。TACE术后,CT显示肿瘤包膜病灶多于MRI,组间比较差异有统计学意义(P<0.05)。结论在肝癌介入术后肿瘤活性的评估中MRI和CT各具有优势,两种方法联合应用可进一步提升诊断效能。

Objective To evaluate the value of MRI and CT in evaluating the tumor activity after interventional surgery for hepatocellular carcinoma.Methods From April 2015 to August 2021,63 patients with liver cancer diagnosed by pathological puncture in our hospital were selected as the study subjects.All patients underwent CT and MRI examination after interventional surgery,and digital subtraction angiography was used as the gold standard to compare the evaluation value of the two imaging methods for tumor activity.Results The detection rate of CT active lesions was lower than that of MRI(P<0.05).The accuracy and sensitivity of MRI were higher than those of CT(P<0.05).After TACE,CT showed more tumor capsule lesions than MRI,and the difference between the two groups was statistically significant(P<0.05).Conclusion Both MRI and CT have advantages in the evaluation of tumor activity after interventional surgery for hepatocellular carcinoma.The combined application of the two methods can further improve the diagnostic efficiency.
