摘要
目的探讨多层螺旋CT血管成像对肺隔离症的诊断价值。方法在13例经病理证实肺隔离症患者中,经多层螺旋CT平扫与增强扫描,并结合最大强度投影(MIP)及容积再现(VR)技术,显示异常血管与病灶的关系。结果13例肺隔离症患者中,9例病灶位于左下叶,4例病灶位于右下叶,11例为叶内型,2例为叶外型,异常供血全部来自胸主动脉。CT平扫表现为肿块形8例,不规则形5例。血管成像重组技术中13例均清晰显示异常体动脉供血。结论多层螺旋CT血管成像并结合重组技术能提高诊断肺隔离症的准确性,具有重要的诊断价值。
Objective To evaluate the diagnostic value of multi-slice spiral CT angiography (MSCTA)in the pulmonary sequestration. Methods Among 13 patients with proven pulmonary sequestration (PS) by pathological examination the plain and enhancement multi-slice spiral CT (MSCT) coupled with techniques of maximum intensity projection (MIP) and volume rendering (VR) were taken to reveal the relationship between abnormal vessels and lesions. Results In the 13 cases the lesion at the left lower lobe was 9and at the right lower lobe 4. Intralobar type was 11 cases ,extralobar type only 2, and the abnormal supplying arteries were from the thoracic aorta. On plain CT scan images, the lesions in mass shape were found in 8 cases, irregular shape 5. On MIP and VR images could clearly displayed abnormal supplying arteries from systemic arteries in all patients. Conclusion MSCTA in combination with techniques of MIP and VR are possessed of important value for making a correct diagnosis of PS.
