使用专门设计的射频线圈、标准和高分辨率成像技术以及各种自旋回波和反转恢复脉冲序列，在24名患者中获得颈部磁共振（MR）图像。由于血流的固有对比，MR比CT更容易识别颈部血管结构。所有病例的喉骨架、咽旁组织、气管、甲状腺、食管和肌肉均通过MR识别，其形态学标准与CT标准相当。高分辨率MR的空间分辨率略低于高分辨率CT。然而，条纹伪影由于运动和X射线束硬化往往限制CT，但不影响MR。解剖分辨率是最好的使用高分辨率自旋回波图像TR = 2.0秒和TE = 28毫秒，因为这种成像技术提供了良好的对比度之间的正常组织，并具有最高的信噪比。随着空间分辨率的进一步提高，MR可能成为颈部成像的重要技术。
Magnetic resonance (MR) images of the neck were obtained in 24 patients using a specially designed radio-frequency coil, standard and high-resolution imaging techniques, and a variety of spin echo and inversion recovery pulse sequences. Cervical vascular structures were more easily identified with MR than with CT because of the inherent contrast of flowing blood. The laryngeal skeleton, paralaryngeal tissues, trachea, thyroid, esophagus, and muscles were identified in all cases by MR using morphologic criteria comparable with CT criteria. The spatial resolution of high-resolution MR was slightly inferior to high-resolution CT. However, streak artifacts due to motion and x-ray beam hardening often limited CT, but did not affect MR. Anatomic resolution was best using high-resolution spin echo images obtained with TR = 2.0 seconds and TE = 28 msec because this imaging technique offered excellent contrast between normal tissues and had the highest signal-to-noise ratio. With further improvements in spatial resolution MR is likely to become an important technique for imaging the neck.
