目的探讨MRI肝脏快速容积成像技术(MRI-LAVA)序列与增强CT扫描在肝脏结节性病变中的诊断价值。方法选取2012年1月—2013年1月平昌县人民医院收治的30例肝脏结节性病变患者,均经手术病理学证实,均采用MRI-LAVA序列与增强CT扫描,对两种方法诊断结果进行分析,并比较病灶>3cm及≤3cm的诊断准确率。结果≤3cm肝脏结节性病灶有31个,增强CT扫描诊断出19个(61.29%),MRI-LAVA序列诊断出27个(87.10%),两者诊断准确率比较,差异有统计学意义(P<0.05);>3cm肝脏结节性病灶10个,增强CT诊断出9个(90.00%),MRI-LAVA序列诊断出9个(90.00%),两者诊断准确率比较,差异无统计学意义(P>0.05)。结论在肝脏结节性病变临床诊断中,采用MRI-LAVA序列诊断有利于发现更多的肝脏结节性病变,同时对≤3cm小结节性病变诊断准确率较高。
Objective To investigate the diagnostic value of MRI-LAVA and enhanced CT in the diagnosis of hepatic nodular lesions. Methods From January 2012 to January 2013, 30 patients with nodular lesions of liver in Pingchang County People’s Hospital were confirmed by surgery and pathology. MRI-LAVA sequence and enhanced CT scan were used to diagnose the two methods Results were analyzed and the diagnostic accuracy of lesions> 3cm and ≤3cm was compared. Results There were 31 nodular lesions ≤3cm, 19 (61.29%) with enhanced CT and 27 (87.10%) with MRI-LAVA. The diagnostic accuracy of the two methods was statistically significant ( P <0.05). There were 10 nodular lesions> 3 cm in diameter, 9 (90.00%) in enhanced CT and 9 (90.00%) in MRI-LAVA. There was no significant difference in diagnostic accuracy between the two Significance (P> 0.05). Conclusion In the clinical diagnosis of nodular lesions in the liver, MRI-LAVA sequence diagnosis is helpful to find more liver nodular lesions, while the accuracy of diagnosis of ≤ 3cm nodular lesions is high.
