摘　　要：目的:评价MRI普美显增强在诊断肝脏局灶性结节增生(FNH)的应用价值。方法:回顾性分析10例FNH患者(4例12个病灶经病理证实,6例10个病灶复查无变化)的MRI平扫、常规Gd-DTPA及(或)普美显动态增强扫描资料,其中常规增强5例,普美显增强7例。分析各检查方法对FNH中心瘢痕的显示率及FNH诊断的准确度。结果:10例FNH患者共22个病灶,单发型4例,多发型6例,其中1例有8个病灶,5例有2个病灶。22个病灶直径为0.5~12cm,平均2.8cm。MRI平扫、Gd-DTPA增强及普美显增强对病灶及中心瘢痕显示率分别71%/28%、100%/61%、100%/100%。诊断FNH可能性大(例):普美显增强6/7、Gd-DTPA增强2/5、MRI平扫2/10。结论:MRI普美显增强诊断FNH优于常规Gd-DTPA增强,可作为FNH诊断首选方法。Objective:Evaluation of Gd-EOB-DTPA enhancement scanning in the diagnosis of hepatic focal nodular hyperplasia(FNH)of the application value.Methods:Retrospective analysis of 10 cases FNH routine MRI scan in patients with Gd-DTPA and(or)the dynamic enhanced scan data.4 cases of 12 lesions confirmed by pathology,6 cases of 10 lesions review no change.The conventional enhancement in 5 cases,Gd-EOB-DTPA’s enhancement in 7 cases.Analysis of various inspection methods for FNH and scar at the centre of the display rate and FNH diagnostic accuracy.Results:Total 22 lesions were detected in 10 patients.Single hair 4 cases,6 cases of hairstyle,1 cases had eight lesions,5 cases with 2 lesions.22 lesions of 0.5 to 12cm in diameter,an average of 2.8cm.MRI plain scan,Gd-DTPA enhancement and Gd-EOB-DTPA enhancement of the detection rate of lesion/centre scar:71%/28%,100%/61%,100%/100%.Diagnosis of FNH likely(cases):Gd-EOB-DTPA enhancement 6/7,Gd-DTPA enhancement 2/5,MRI plain scan:2/10.Conclusion:Gd-EOB-DTPA enhancement scanning in the diagnosis of FNH is superior to the conventional Gd-DTPA enhancement,can be used for diagnosis of FNH preferred.
