Post Surgical Spinal Evaluation

One of the most challenging areas of diagnosis is to be found in acquiring and interpreting medical images in the patient who has undergone lumbosacral surgery for spinal degenerative disease. The section illustrates the features of expected and abnormal postsurgical spinal imaging. These discussions provide the background, practical information, and graphic examples necessary to enable the medical imaging physician to better approach the clinicoradiologic evaluation of the postsurgical patient.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/145202/1/cpmia0808.pd

Spinal Canal Stenosis

This unit presents a basic protocol for fast spin echo sequences for imaging to diagnose stenosis of the spinal canal. Spinal stenosis is defined generally as a narrowing of one or more of the following: the central canal, foramina, and lateral recesses of the lumbar spine. Specifically, this stenosis can be classified into three types as defined by location: (a) stenosis of the central spinal canal, (b) stenosis of the intervertebral spinal neural foramen or foramina, and (c) stenosis of the lateral recess(es) of the central spinal canal.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/145322/1/cpmia0802.pd
