To depict the complex anatomy of the axilla with CT and MR imaging.
The axillary regions of 2 cadavers (with arms hyperabducted) were examined by means of CT and MR. In this position the cadavers were frozen and cryosectioned. The anatomical sections documented by the MR and CT images were compared and anatomical structures were designated. To show the reproducibility of the anatomical structures and to find variations, 20 volunteers were also examined by MR, and 20 consecutive patients without axillary symptoms were examined by CT.
The complexity of the axilla was excellently shown by both CT and MR, but MR was able to demonstrate more detail in the small vessels and in the brachial plexus. The comparability of the examinations of the different individuals was best in the axial plane. Some differences appeared in the coronal and sagittal planes caused by different positions of the arm.
Axillary anatomy was demonstrated in detail and was reproducible with CT and MR imaging.
通过CT和MR成像描绘腋窝的复杂解剖结构。
对2具尸体（手臂过度外展）的腋窝区域进行CT和MR检查。在此位置将尸体冷冻并进行冰冻切片。对比由MR和CT图像记录的解剖切片并确定解剖结构。为了显示解剖结构的可重复性并发现变异情况，还对20名志愿者进行了MR检查，对20例无腋窝症状的连续患者进行了CT检查。
CT和MR均能很好地显示腋窝的复杂性，但MR能够在小血管和臂丛神经方面显示出更多细节。不同个体检查结果在轴位平面的可比性最佳。由于手臂位置不同，在冠状面和矢状面出现了一些差异。
CT和MR成像能够详细显示腋窝解剖结构且具有可重复性。
