To evaluate the clinical utility of time-resolved contrast-enhanced magnetic resonance angiography (MRA) in the evaluation of vascular orbital tumors.
Retrospective medical record review of patients with vascular orbital lesions imaged with Time-Resolved Imaging of Contrast KineticS (TRICKS; GE Healthcare [Chalfont St Giles, England]) MRA, a noninvasive dynamic imaging modality.
Five patients with orbital vascular tumors were evaluated using TRICKS MRA. These included 1 patient with a cavernous hemangioma, 2 patients with orbital varices, 1 patient with an orbitocutaneous arteriovenous malformation, and 1 patient who had a solitary fibrous tumor with features of a hemangiopericytoma. In 2 patients, diagnoses were altered as a result of TRICKS MRA. In addition, a young patient with a large orbitocutaneous arteriovenous malformation involving the ophthalmic artery was followed perioperatively and noninvasively using TRICKS MRA, which produced exquisite images and added substantial value in the care of these patients.
Dynamic MRA in the form of TRICKS is a newly available imaging modality with great potential for improving the evaluation and management of patients with complex orbital tumors.
评估时间分辨对比增强磁共振血管造影（MRA）在眼眶血管性肿瘤评估中的临床应用价值。
对采用对比剂动力学时间分辨成像（TRICKS；通用电气医疗集团[英国柴郡查尔方特圣贾尔斯]）MRA成像的眼眶血管性病变患者进行回顾性病历审查，TRICKS是一种非侵入性动态成像方式。
采用TRICKS MRA对5例眼眶血管性肿瘤患者进行了评估。其中包括1例海绵状血管瘤患者、2例眼眶静脉曲张患者、1例眶周皮肤动静脉畸形患者以及1例具有血管外皮细胞瘤特征的孤立性纤维瘤患者。2例患者的诊断因TRICKS MRA而改变。此外，对1例患有累及眼动脉的大型眶周皮肤动静脉畸形的年轻患者在围手术期及术后采用TRICKS MRA进行无创随访，该检查生成了高质量图像，为这些患者的治疗提供了重要价值。
TRICKS形式的动态MRA是一种新的成像方式，在改善复杂眼眶肿瘤患者的评估和管理方面具有巨大潜力。
