目的探讨对比增强三维磁共振血管成像（3D MRA）对肺隔离症体循环血供的诊断价值。方法对3例疑诊为肺隔离症的患者行增强三维MRA检查。将MR图像与手术结果进行比较。结果增强3D MRA清晰显示了来自降主动脉的体循环动脉供血下叶基底段。肺静脉从这些节段，其中两例引流到左心房，也被检测到。MRA图像与手术中观察到的图像一致。结论对比增强3D MRA能准确诊断肺隔离症，可避免更多的侵入性检查。
OBJECTIVE To evaluate the feasibility of contrast enhanced three-dimensional (3D) magnetic resonance angiography (MRA) in identifying the systemic blood supply in pulmonary sequestration. METHODS Three patients who were suspected of pulmonary sequestration were examined by contrast enhanced 3D MRA. MR images were compared with surgical findings. RESULTS Contrast enhanced 3D MRA clearly demonstrated systemic arteries from the descending thoracic aorta supplying the basilar segments of the lower lobe in each case. Pulmonary veins from these segments, which drained into the left atrium in two cases, were also detected. MRA images were consistent with those observed in surgery. CONCLUSION Contrast enhanced 3D MRA allows accurate diagnosis of pulmonary sequestration and may obviate the need for more invasive investigations.
