目的：探讨三维时间分辨对比动态增强MR血管成像(three dimensional time-resolved imaging of contrast kinetics，MRA 3D-TRICKS)在临床中的应用价值。材料与方法搜集60例行TRICKS检查的患者，于TRICKS扫描前采集感兴趣区蒙片，团注对比剂后采集15～20时相。结果60例患者均完成TRICKS检查，图像均达到诊断要求。11例颅内动脉成像显示良好(6例动静脉畸形、2例头皮动脉静脉畸形和3例静脉窦血栓)。5例颈动脉血管成像显示良好(3例颈总动脉分叉处狭窄、1例左侧椎动脉狭窄和1例颈部神经纤维瘤)。10例脊髓血管畸形显示良好。上肢血管成像为5例血管瘤。下肢和足部血管成像22例(10例为动脉静脉瘘、假性动脉瘤1例、3例糖尿病患者下肢血管闭塞和8例为下肢动脉狭窄)。盆腔血管成像7例(2例髂骨骨肉瘤、3例股骨骨肉瘤和2例纤维瘤)。结论 TRICKS能清晰显示多个部位的血管系统，并能从多个角度观察病变血管。TRICKS因其时间分辨率高、诊断准确率高，在血管性病变的无创性诊断中具有重要的作用。

Objective: To investigate the value of MR angiography using time-resolved imaging of contrast kinetics (TRICKS) in clinical practice. Materials and Methods:60 patients performed TRICKS in our hospital were enrolled in this study. Masks were scanned before TRICKS and 15-20 phases were acquired after contrast agent bonus injection. Results:All 60 patients completed TRICKS and images met diagnostic requirements. 11 cases of intracranial angiography had good image quality, including arteriovenous malformation (n=6), scalp arteriovenous malformation (n=2) and venous sinus thrombosis (n=3). 5 cases of cervical angiography displayed well including bifurcation of carotid artery stenosis (n=3), left vertebral artery stenosis (n=1) and neurofibroma (n=1). 10 cases of spinal vascular malformation showed well on TRCIKS. Upper limbs angiography displayed 5 cases hemangioma. 22 cases of lower limbs and foot angiography showed arteriovenous ifstula (n=10), pseudoaneurysm (n=1), lower limbs vascular occlusion in patients with diabetes mellitus (n=3) and lower limbs arteries stenosis (n=8). 2 cases of iliac osteosarcoma, 3 cases of femur osteosarcoma and 2 cases of ifbroma showed well on pelvic TRICKS (n=7). Conclusions:TRICKS is able to describe clearly vascular system and demonstrate lesions by many aspects. It plays an important role in the non-invasive diagnosis of vascular diseases, for its high temporal resolution and accuracy.
