Abstract
Objective To evaluate the multi-slice spiral CT (MSCT) reinforced thin layer scanning and image processing technique in the diagnosis of pulmonary sequestration (PS) value. Methods Analysis the clinical operation pathology, aortic angiography confirmed 21 cases of chest multi-slice spiral CT plain scan and CTA of pulmonary sequestration were examined, multi planar reconstruction (MPR), and the reconstruction of maximum intensity projection (MIP), volume rendering (VR). Results 21 cases were solitary, pulmonary sequestration (PS) located in the left lower lobe in 14 cases, right pulmonary lower lobe in 7 cases;for the performance of lung field of tanacu, solid mass in 15 cases, 6 cases of cystic lesion; artery in 21 cases of PS were derived from autologous artery, including 18 cases from aortic branch, 3 cases from the abdominal aorta. Conclusion Multi slice spiral CT (MSCT) after treatment technology can accurately, visual display of pulmonary sequestration artery, can replace invasive DSA examination.关键词
