研究概览
简要总结
Participants will receive an MRI with a custom-built MRI coil for each participant. The purpose is to find out whether this custom-built MRI coil can help doctors see the different parts of the spine as well as or better than they can with standard CT myelograms.

结局指标
主要结局
Difference of calculated doses to the cauda equine and spinal cord based upon MRI coil vs CT myelogram used to define each structure
时间窗: 6 months
The calculated doses to the cauda equine and spinal cord will be compared and evaluated for significant difference based upon the imaging modality (MRI coil vs CT myelogram) used to define each structure, with all other target and avoidance volumes being equal in the same patient.
