To demonstrate the anatomy of the Meckel cave, which is normally seen by means of dissection, with high-resolution computed tomography (CT) and magnetic resonance (MR) imaging.
Twenty cadaver specimens were scanned with 1-mm contiguous axial and coronal CT sections. Seven specimens were also scanned with 1-mm contiguous parasagittal sections and were dissected for correlation with CT images. Two volunteers also underwent high-resolution, fast spin-echo MR imaging. MR images were compared with the CT images and the results of dissection.
Dissection and CT and MR imaging demonstrated that the trigeminal nerve within the Meckel cave consists of numerous small fibers and that the trigeminal ganglion consists of a small amount of solid tissue.
In vivo, high-resolution, fast spin-echo imaging can demonstrate the anatomy of the trigeminal nerve in the Meckel cave because of improved spatial and contrast resolution.
通过高分辨率计算机断层扫描（CT）和磁共振（MR）成像来展示通常通过解剖才能看到的Meckel腔的解剖结构。
对20具尸体标本进行1毫米连续轴向和冠状CT扫描。7个标本还进行了1毫米连续矢状旁切面扫描，并进行解剖以与CT图像进行对照。两名志愿者也接受了高分辨率快速自旋回波MR成像。将MR图像与CT图像及解剖结果进行比较。
解剖以及CT和MR成像显示，Meckel腔内的三叉神经由许多小纤维组成，三叉神经节由少量实体组织组成。
在活体中，高分辨率快速自旋回波成像由于空间和对比度分辨率的提高，能够展示Meckel腔内三叉神经的解剖结构。
