摘要
目的 评价MRI在诊断肺隔离症中的价值。资料与方法 回顾性分析 5例经手术病理证实的肺隔离症患者的MRI资料 ,评价其显示病变及其相关血管的能力。结果 5例病变均位于下肺后基底段 ,肺隔离症的MRI表现包括肺野内块影 ,伴有囊变 (n =4 )、支气管扩张 (n =1) ,MRA及CE MRA能够清楚显示源自降主动脉的异位血供 (n =4 )。结论 MRI是诊断肺隔离症的一种安全、有效的非创伤检查手段 ,能在一定程度上取代DSA。
Objective To evaluate MRI in the diagnosis of pulmonary sequestration.Materials and Methods MRI findings in 5 cases with surgically and pathologically proved pulmonary sequestration were retrospectively analyzed. MRI ability in displaying the lesions and related vessels was evaluated.Results All the lesions were located in the posterior basal segments of the lower lobes. MRI findings of pulmonary sequestration included mass with cystoid degeneration in the lung field (n=4) and bronchiectasis (n=1). The ectopic feeding arteries originated from the descending aorta (n=4) were well demonstrated on MRA and CE MRA.Conclusion MRI is an effective, non invasive and safe technique, which can substitute for DSA to a certain degree for the diagnosis of pulmonary sequestration.
