摘要/Abstract

摘要： 目的比较使用3.0 T 磁共振-肝脏容积快速采集（MR-LAVA）序列多期动态增强扫描定性诊断肝硬化结节病变的价值。方法 2015年1月~2017年8月我院诊治的乙型肝炎肝硬化患者,行3.0 T MR-LAVA序列多期动态增强扫描和CT增强检查。比较两种检查方法检出病灶情况及其表现特征。结果 MR-LAVA序列扫描检出病灶80例,而增强CT扫描检出病灶73例（91.3%）;MR-LAVA序列检查定性诊断为局灶性结节性增生40例,血管瘤13例,原发性肝癌10例（均表现为富血供病变）,转移瘤17例,而CT检查定性诊断为局灶性结节增生34例,血管瘤12例,肝细胞癌9例和转移瘤18例。结论 3.0 T MR-LAVA序列多期动态增强扫描能提高对肝硬化结节病变的定性诊断,值得临床进一步验证。

Abstract: Objectiv To investigate the value of 3.0 T MR-liver acceleration volume acquisition （LAVA） sequence multi-phase dynamic enhanced scanning in qualitative diagnosis of intrahepatic nodular lesions in patients with liver cirrhosis（LC）. Methods Patients with LC were recruited in our hospital between January 2015 and August 2017. All patients underwent multi-phase dynamic contrast-enhanced CT scan and 3.0 T MR-LAVA sequences scan. Results MR-LAVA scan revealed 80 patients with intrahepatic lesions,while out of them the CT scan demonstrated in 73 cases （91.3%）;the MR-LAVA provided diagnosis of focal nodular hyperplasia in 40,hepatic hemangioma in 13,primary liver cancer in 10, and metastatic tumors in 12 patients,while the CT scan diagnosed focal nodular hyperplasia in 34,hepatic hemangioma in 12,primary liver cancer in 9,and metastatic tumors in 18. Conclusion Multi-phase dynamic enhanced scan of 3.0 T MR-LAVA sequence scan might be an efficient approach in qualitatively diagnosing intrahepatic lesions,which could help clinicians to make decisions early.
