Magnetic resonance angiography (MRA) is a recently developed, noninvasive vascular imaging technique. The authors of this investigation assessed the diagnostic value of MRA, along with its influence on therapeutic decisions, in 11 patients with a variety of head and neck disorders. In 5 patients, MRA diagnosed or ruled out an intrinsic vascular lesion. MRA was used to evaluate 5 of 8 patients with cancer for evidence of direct tumor involvement of vascular structures. Other uses of MRA included preoperative determination of tumor vascularity and delineation of anatomic relationships between normal vessels and head and neck pathology. Overall, MRA results guided management in 10 patients, and in some cases it determined the extent of surgical intervention. Because MRA is safer and more practical than traditional angiography, the authors recommend more frequent use of this imaging technique in the practice of head and neck surgery.
磁共振血管造影（MRA）是一种最近开发的非侵入性血管成像技术。本研究的作者评估了MRA在11例患有各种头颈部疾病患者中的诊断价值及其对治疗决策的影响。在5例患者中，MRA诊断或排除了内在血管病变。MRA用于评估8例癌症患者中的5例，以寻找血管结构受肿瘤直接侵犯的证据。MRA的其他用途包括术前确定肿瘤血管情况以及描绘正常血管与头颈部病变之间的解剖关系。总体而言，MRA结果指导了10例患者的治疗，在某些情况下还确定了手术干预的范围。由于MRA比传统血管造影更安全、更实用，作者建议在头颈部外科实践中更频繁地使用这种成像技术。
