摘　　要：目的:观察磁共振肝脏快速容积成像技术(MRI-LAVA序列)和增强CT对肝脏结节性病变的检查结果,对比二者的诊断价值.方法:回顾性分析2016年3月-2018年11月于笔者所在医院接受治疗的肝脏结节性病变患者临床资料,从中选取接受MRI-LAVA序列检查和增强CT检查的70例患者资料.分析两种检查结果,并以病理学检查为"金标准",比较两种检查对≤3 cm病灶、>3 cm病灶的诊断准确率.结果:MRI-LAVA序列检查共检出病灶86处,包括转移瘤病灶、肝硬化再生结节病灶、肝细胞肝癌病灶、血管瘤病灶、局灶性结节增生病灶、肝硬化炎性结节病灶、肝硬化增生结节病灶;增强CT检查共检出病灶77处,包括转移瘤病灶、肝硬化再生结节病灶、肝细胞肝癌病灶、血管瘤病灶、局灶性结节增生病灶、肝硬化增生结节病灶;MRI-LAVA序列检查对≤3 cm病灶的诊断准确率高于增强CT检查,差异有统计学意义(P<0.05);两种检查对>3 cm病灶的诊断准确率比较,差异无统计学意义(P>0.05).结论:与增强CT检查相比,MRI-LAVA序列检查在肝脏结节性病变诊断中的应用价值较高,不仅能检出更多类型的病灶,而且对≤3 cm病灶具有更高的诊断准确率.Objective:To observe the results of magnetic resonance imaging of the liver acceleration volume acquisition(MRI-LAVA sequence)and enhanced CT in diagnosis of nodular liver lesions,and to compare the diagnostic value of the two.Method:The clinical data of patients with nodular liver lesions who treated in our hospital from March 2016 to November 2018 were retrospectively analyzed,and 70 patients with MRI-LAVA sequence and enhanced CT were selected.The results of two examination were analyzed,and the pathological examination was taken as the gold standard,and the diagnostic accuracy of two examinations in lesions≤3 cm and lesions>3 cm were compared.Result:A total of 86 lesions were detected by MRI-LAVA sequence,including metastatic lesions,cirrhosis regenerated nodular lesions,hepatocellular carcinoma lesions,hemangioma lesions,focal nodular hyperplasia lesions,cirrhosis inflammatory nodular lesions,cirrhosis dysplastic nodular lesions.A total of 77 lesions were detected by enhanced CT,including metastatic lesions,cirrhosis regenerated nodular lesions,hepatocellular carcinoma lesions,hemangioma lesions,focal nodular hyperplasia lesions,cirrhosis dysplastic nodular lesions.The diagnostic accuracy of MRILAVA sequence in lesions≤3 cm was higher than that of enhanced CT,and the difference was statistically significant(P<0.05).The diagnostic accuracy of two examinations in lesions>3 cm were compared,and the difference was not statistically significant(P>0.05).Conclusion:Compared with enhanced CT,MRI-LAVA sequence has higher application value in diagnosis of nodular liver lesions,which not only can detect more types of lesions,but also have higher diagnostic accuracy for lesions≤3 cm.
