摘要
目的探讨64层螺旋CT血管成像技术对肺动静脉瘘的诊断价值。方法对12例临床怀疑肺动静脉瘘的患者行CT血管成像检查。对所有扫描图像行容积再现(VR)、最大密度投影(MIP)以及冠状多平面重组(MPR)。结果12例患者均确诊为肺动静脉瘘,7例为单发,5例为多发,共发现20处肺动静脉瘘,除漏诊1例合并位于近心位置的3处肺动静脉直接交通外,其余病变均诊断正确且无遗漏。结论64层螺旋CT血管成像技术可以无创地诊断肺动静脉瘘,为治疗方案的制定及术后随访提供依据。
Objective To explore the value of 64-slice spiral CT angiography in diagnosis of pulmonary arteriovenous fistulas （PAVF）. Methods 12 patients with suspect PAVF were performed by enhanced scan with 64-SliceCT. Two-dimensional and three-dimensional reformation were performed in all cases including coronal multiplanar reconstruction （MPR） , maximum intensity projection （ MIP）, volume rendering （VR）. Results 12 cases were diagnosed as PAVF by 64-SliceCT angiography . Single PAVF in 7 cases , Multi- PAVF in 5cases. We found 20 lesions in 12 patients, Except direct multi-pulmonary arteriovenous fistulas in the area of near the heart in one case. Conclusion 64-slice spiral CT angiography is a useful and noninvasive means to identify PAVF and is also useful for therapeutic planning and postoperative follow-up.
