摘要目的：探讨联合应用3D FIESTA-C、T2W IDEAL序列对臂丛节前、节后神经相关疾病的应用价值。方法：①采用GE 3.0T磁共振对20例志愿者行臂丛节后神经STIR、T2W IDEAL序列冠状位扫描，从信噪比（SNR）、对比噪声比（CNR）及图像伪影3个方面进行两种扫描序列的图像质量评价；②收集25例臂丛神经相关病变患者行常规序列及3D FIESTA-C、T2W IDEAL序列扫描，其中9例病灶行Gd-DTPA增强扫描，观察臂丛神经相关病变的影像学表现。结果：①STIR、T2W IDEAL序列均能显示臂丛神经节后段，T2W IDEAL序列较STIR序列的图像伪影少，T2W IDEAL序列较STIR序列的SNR、CNR高（P<0.001）；②25例臂丛神经病变中包括4例臂丛神经创伤性病变（节前、节后创伤各2例）；臂丛神经相关肿瘤13例（原发性神经源性肿瘤包括3例神经纤维瘤病，6例神经鞘瘤，1例恶性神经鞘膜瘤；继发性肿瘤包括转移瘤3例），其他包括放射性臂丛神经损伤及急性臂丛神经炎各2例，多发神经鞘囊肿4例。结论：T2W IDEAL序列能较好显示臂丛节后神经，联合应用3D FIESTA-C、T2W IDEAL序列能够较直观、可靠地观察臂丛节前、节后神经相关病变。

Abstract：Objective: To discuss the application value of 3.0T MRI in brachial plexopathy combined use of 3D FIESTA-C and T2W IDEAL sequence． Methods: ①Coronary scanning of short time inversion recovery sequence(STIR) and T2W IDEAL sequence were scanned on twenty volunteers using GE 3.0T magnetic resonance． The signal to noise ratio（SNR）, contrast to noise ratio(CNR) and image motion artifact were evaluated on this two sequences． ②Twenty-five cases of brachial plexopathy were scanned on 3D FIESTA-C and IDEAL sequence besides general sequences, in which 9 cases underwent Gd-DTPA enhanced MRI． MRI of brachial plexus lesions were evaluated. Results: ①T2W IDEAL was better than STIR(5/20, 9/20) on the image motion artifact. Quantitatively, both SNR and CNR for IDEAL(45.3±12.6 and 27.1±12.1, respectively) were significantly higher(P<0.001) than those for STIR(17.4±6.1 and 8.2±4.7, respectively)． ②The patients’ diseases comprised of: 4 cases of brachial plexus injury lesions(２ preganglionic and postganglionic brachial plexus injury respectively), 13 brachial plexus tumors(primary tumors including 3 neurofibromatosis, 6 schwannomas, 1 malignant nerve sheath tumor; secondary tumors including 3 metastases), 2 radiation neuropathy and acute brachial plexus neuritis respectively, and 4 multiple nerve sheath cysts． Conclusion: T2W IDEAL sequence can display postganglionic brachial plexus perfectly． Combined use of 3D FIESTA-C and T2W IDEAL sequence, the preganglionic and postganglionic brachial plexus lesions can be observed clearly and reliably．
