(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.
(1) 背景：小腿动脉的术前成像对于腓骨移植手术规划至关重要。本研究的目的是评估非对比增强（CE）静态间隔层选（QISS）磁共振血管造影（MRA）在可靠显示小腿动脉解剖结构和通畅情况以及术前确定腓骨穿支的存在、数量和位置方面的可行性和临床价值。(2) 方法：对50例口腔颌面肿瘤患者的小腿动脉解剖结构、狭窄情况以及腓骨穿支的存在、数量和位置进行了评估。将腓骨移植术后患者的结果与术前成像、人口统计学和临床参数进行关联分析。(3) 结果：100条腿中有87%存在规则的三支供血。QISS-MRA能够准确确定解剖结构异常患者的分支模式。87%的腿中发现了腓骨穿支。超过94%的小腿动脉无相关狭窄。50%的患者接受了腓骨移植，成功率为92%。(4) 结论：QISS-MRA有潜力作为一种术前非对比增强MRA技术，用于诊断和检测小腿动脉的解剖变异及其病变，以及评估腓骨穿支。
