[Abstract] 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 fistula (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 fibroma 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.
