摘　　要：目的 探讨多层螺旋CT增强及后处理对弥漫型肺动静脉瘘的诊断.方法 对临床怀疑弥漫型肺动静脉瘘6例（男2例,女4例,平均年龄29.8岁）患者进行CT增强扫描,扫描所得容积包输入后处理工作站,应用影像后处理工作站MIP、MPR、VR等技术进行分析,诊断结果与手术、随访及DSA结果进行对照.结果 6例弥漫型肺动静脉瘘患者,4例为两肺弥漫点状影,共45个病灶;2例为两肺多发点状（共10个病灶）、结节状及肿块影（共6个病灶）.影像表现为不规则点状、结节状及肿块性明显强化影,其中点状影可见逗点影及磨玻璃影,结节及肿块影可见明显增粗迂曲供血动脉及引流静脉,分别与肺动脉及静脉相连.结论 MSCT增强及后处理对弥漫型动静脉瘘诊断具有重要意义.Objective To discuss multi-slice spiral CT（MSCT） contrast-enhanced scan and post-processing in diagnosing diffuse pulmonary arteriovenous fistula （PAVF）. Methods MSCT contrast enhanced scans were performed in 6 patients （ 2 men and 1 women,mean age 29.8 years） clinically suspected of PAVFs. The images were post-processed at workstation（ including MPR, MIP and VR）. The results were retrospectively compared with that of surgery,DSA and follow-up. Results 6 cases were detected with PAVFs by MSCT contrast-enhanced scans. The lesions appeared as bilateral lung diffuse point-like shadows in 4 patients （15 foci）, diffuse point-like （10 foci） ,nodular and mass （6 foci） shadows in bilateral lungs in 2 cases. The lesions showed irregular spots, noddular and mass significantly enhanced on MSCT contrast-enhanced scans and comma shadow and ground glass opacity could be seen in side the lesions,obvious dilated and tortuous feeding arteries and draining veins connected with the pulmonary artery and vein wee also showed. Conclusion MSCT contrast-enhancement and post processing images are of important value in diagnosing the PAVFs.
