(1)背景：术前下肢动脉成像对于腓骨移植的计划是必不可少的。本研究的目的是评价非造影剂增强（CE）静息间隔选择性切片（QISS）磁共振血管造影（MRA）的可行性和临床价值，以可靠地显示小腿动脉的解剖结构和通畅性，并在术前确定腓骨穿支的存在、数量和位置。(2)研究方法：对50例口腔颌面部肿瘤患者的小腿动脉的解剖和狭窄情况以及腓骨穿支的存在、数量和位置进行了测定。腓骨移植后患者的术后结果与术前影像学、人口统计学和临床参数相关。(3)结果：100条下肢中有87%的下肢存在规则的三支血管供血。QISS-MRA能够准确地分配分支模式的异常解剖的患者。87%的下肢可见腓骨穿支。超过94%的小腿动脉没有相关狭窄。50%的患者进行了腓骨移植，成功率为92%。(4)结论：QISS-MRA有可能用作术前非CE MRA技术，用于诊断和检测小腿动脉的解剖变异及其病理，以及评估腓骨穿支。
(1) Background: Preoperative imaging of the lower leg arteries is essential for planning fibular grafting. The aim of this study was to evaluate the feasibility and clinical value of non-contrast-enhanced (CE) Quiescent-Interval Slice-Selective (QISS)-magnetic resonance angiography (MRA) for reliably visualizing the anatomy and patency of the lower leg arteries and for preoperatively determining the presence, number, and location of fibular perforators. (2) Methods: The anatomy and stenoses of the lower leg arteries and the presence, number, and location of fibular perforators were determined in fifty patients with oral and maxillofacial tumors. Postoperative outcomes of patients after fibula grafting were correlated with preoperative imaging, demographic, and clinical parameters. (3) Results: A regular three-vessel supply was present in 87% of the 100 legs. QISS-MRA was able to accurately assign the branching pattern in patients with aberrant anatomy. Fibular perforators were found in 87% of legs. More than 94% of the lower leg arteries had no relevant stenoses. Fibular grafting was performed in 50% of patients with a 92% success rate. (4) Conclusions: QISS-MRA has the potential to be used as a preoperative non-CE MRA technique for the diagnosis and detection of anatomic variants of lower leg arteries and their pathologies, as well as for the assessment of fibular perforators.
