摘要
目的研究多层螺旋CT容积对肺隔离症的应用价值。方法对经外科手术及病理证实的11例肺隔离症患者多层螺旋CT血管造影,利用容积再现(VR)技术,分析异常血管与病灶的关系。结果 11例患者中,7例病灶位于左下叶,4例病灶位于右下叶,异常供血全部来自胸主动脉。MSCT平扫表现为囊实性肿块6例,其他不规则形5例。VR重组技术中11例能明确显示异常体动脉供血及肺内血管网。结论多层螺旋CT血管造影及结合容积再现重组技术能直观显示肺隔离症的异常体动脉供血及肺内血管网,具有重要的临床应用价值。
Objective To evaluate the diagnostic value of VR techniques with multi-slice spiral CT in the pulmonary sequestration.Methods MSCT angiography were performed and reconstructed imaging VR in 11 patients with surgically confirmed pulmonary sequestration(PS),The emphasis was shown the relationship between abnormal vessels and lesions.Results Among 11 cases PS,the lesion was located at the left lower lobe in 7 and at the right lower lobe in 4 cases,abnormal supplying arteries were from the thoracic aorta.On plain CT scan images,the mass-like lesions were found in 6 cases,irregular shape lesions in 5 cases.On VR images clearly displayed abnormal supplying arteries from systemic arteries in all patients.Conclusion MSCT angiographytechnology can accurately and directly display the blood-supply of the segregation tissue.So this method is very important value in PS.
