摘　　要：目的探讨MRA在周围软组织血管瘤和血管畸形中的应用价值。方法回顾性分析61例血管瘤和血管畸形动脉、静脉磁共振血管成像表现。结果13例血管瘤中7例病灶内出现增多且逐渐变细的细小动脉,2例合并有动-静脉瘘形成,6例病灶内未见血管显示。48例血管畸形中35例病变区动、静脉显影,1例仅见动脉显影。动脉成像23例表现为动脉受压变细,5例可见动脉畸形。静脉成像25例显示浅静脉畸形,其中13例合并深静脉畸形,2例仅显示深、浅静脉增多、增粗。8例动、静脉成像均可见动-静脉瘘形成。12例病变区未见血管显影。结论MRA对周围软组织血管瘤和血管畸形的诊断和鉴别有重要价值。Objective To evaluate the role of magnetic resonance angiography （ MRA ） in diagnosing peripheral hemangioma and vascular malformation . Methods 6 1 cases of hemangioma and vascular malformations in peripheral soft tissue were undergone MRA examination. Results Of 13 patients with hemangioma,the arteries within hemangioma were increased and gradually fine from proximal to distal in 7 cases and in company with arteriovenous fistulae in 2 cases, there were no arteries within hemangioma in 6 cases. Vascular malformations were found in 48 patients, arteries and veins of vascular malformation were showed in 35 cases, but arteries of vascular malformations were only showed in one case. Arteries of vascular malformation were showed in 5 cases and the arteries were pressed on arterial angioyraphy in 23 cases. On MR venography（ MRV ） , the shallow malformed veina were showed in 25 cases and in company with deep malformed veina in 13 cases , only the shallow and deep veina increased and thickness be showed in 2 cases. Arteriovcinous fistulae could he seen in 8 cases on MR aterio - venography. There were no vessel be showed in 12 cases within the losions. Conclusion MRA is of significant value in diagnosis and differential diagnosis of peripheral hemangioma and vascular malformations.
