摘要
目的 探讨CT和MRI对肝癌经导管动脉栓塞化疗(TACE)术后残留或复发病灶的评估价值。方法选取93例肝癌TACE患者,均接受CT、MRI及数字减影血管造影(DSA)检查,并以DSA检查结果为金标准,评估CT、MRI检查对肝癌TACE患者术后病灶残留或复发的评估价值。结果 DSA检查显示93例患者共119个病灶中,病灶残留或复发98个,无残留或复发21个。MRI、CT+MRI检查诊断肝癌患者TACE术后病灶残留或复发的灵敏度、准确度、阴性预测值均高于CT检查,诊断TACE术后残留或复发病灶包膜的灵敏度、特异度、准确度、阳性预测值、阴性预测值均高于CT检查,诊断TACE术后残留或复发病灶直径≤5 cm的特异度、准确度、阳性预测值均高于CT检查,差异均有统计学意义(P﹤0.05)。MRI检查诊断肝癌患者TACE术后残留或复发病灶的最大长径明显长于CT检查,病灶最小短径明显短于CT检查,差异均有统计学意义(P﹤0.01)。结论 与CT检查相比,MRI检查对肝癌患者TACE术后残留或复发病灶的诊断价值较高,可以清晰显示病灶包膜及小病灶情况,是一种可靠的肝癌TACE术后疗效评估方式。
Objective To explore the value of CT and MRI in the evaluation of residual or recurrent lesions after transcatheter arterial chemoembolization(TACE) for hepatocellular carcinoma. Method Ninety-three patients with hepatocellular carcinoma undergoing TACE underwent CT, MRI and digital subtraction angiography(DSA). The results of DSA were used as the gold standard to evaluate the value of CT and MRI in evaluating the residual or recurrent lesions of hepatocellular carcinoma patients after TACE. Result DSA showed that of 119 lesions in 93 patients, 98 lesions remained or recurred, and 21 lesions not remained or recurred. The sensitivity, accuracy and negative predictive value of MRI and CT+MRI in the diagnosis of residual or recurrent lesions in patients with hepatocellular carcinoma after TACE were higher than those of CT, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of CT and CT+MRI in the diagnosis of capsule of residual or recurrent lesions after TACE were higher than those of CT,and the specificity, accuracy and positive predictive value of CT and CT+MRI in the diagnosis of residual or recurrent lesions with diameter ≤ 5 cm after TACE were higher than those of CT, and the differences were statistically significant(P<0.05). The maximum long diameter of residual or recurrent lesions in patients with hepatocellular carcinoma diagnosed by MRI after TACE was significantly longer than that of CT, and the minimum short diameter of lesions was significantly shorter than that of CT, and the differences were statistically significant(P<0.01). Conclusion Compared with CT, MRI has higher diagnostic value for residual or recurrent lesions after TACE in patients with hepatocellular carcinoma. It can clearly show the envelope and small lesions of the lesions, and is a reliable method for evaluating the efficacy of TACE in patients with hepatocellular carcinoma.
