ABSTRACT
Objective To assess the value of clinical application of CT pulmonary angiography(CTPA) in diagnosing pulmonary damage of Behcet’s syndrome.Methods 17 patients with Behcet’s syndrome underwent MSCT(Light Speed Plus, GE)with conventional CT scan and CTPA. The two kinds of imaging materials were comparatively studied by chi-square test , and diagnosed by comprehensive imaging appearances. Results The major feature of conventional CT included:bilateral or unilateral pulmonary density were nonhomogeneous in all cases,solitary or multiple pulmonary aneurysmal ecctasia in 9 cases,pulmonary artery growed in 12 cases,irregular and constrictive vascular wall in 6 cases and segmental infiltration in 5 cases.The features of CTPA included:irregular and constrictive pulmonary vascular wall in 15 cases,pulmonary aneurysms in 15 cases,pulmonary artery expansion in 16 cases,pulmonary artery thrombosis in 8 cases.There were statistical differences between conventional CT and CTPA in pulmonary aneurysm and arterial wall changes(?_1~2=5.10,P_10.05).Conclusion CTPA can diagnose pulmonary damage of Behcet’s syndrome in combination with clinic and conventional CT.
