MR三维颅脑容积成像增强扫描序列在舌下神经管区病变中的应用

目的 探讨三维MR颅脑容积成像（3D-BRAVO）增强扫描序列在舌下神经管区病变中的应用价值。方法 对14例舌下神经管区病变患者的MR资料进行回顾性分析，所有病例均行常规MR平扫、增强及3D-BRAVO增强扫描。结果 14例患者于常规平扫序列上可发现病灶，常规增强序列上不能清晰显示舌下神经及舌下神经管，三维颅脑容积成像增强扫描序列上所有病例均能显示舌下神经及舌下神经管，并可进行MPR多方位清楚显示舌下神经管、舌下神经及病灶。结论 3D-颅脑容积成像增强扫描序列较常规扫描提供更多信息，是诊断舌下神经管区病变准确、可靠的扫描序列。

Application of 3D-BRAVO enhanced MR scanning in hypoglossal nerve region lesions

Objective To investigate enhanced scanning sequences of three-dimension brain volume imaging (3D-BRAVO) in diagnosing hypoglossal nerve region lesions.Methods The MR data of 14 patients with clinical diagnosis of hypoglossal nerve region lesions were retrospectively analyzed. All patients underwent conventional MR, enhanced and 3D-BRAVO enhanced MRI scanning.Results The lesions were identified on plain MRI scanning images in all 14 patients. Conventional enhanced scanning could not clearly display the hypoglossal nerve and canal, while 3D-BRAVO enhanced images could clearly revealed them in all patients. In addition, MPR images could clearly display the hypoglossal nerve and canal, as well as the lesions, from multiple aspects.Conclusion Compared with plain and conventional enhanced MRI scanning, 3D-BRAVO enhanced images can provide improved image quality in displaying hypoglossal nerve region lesions.
