Spin echo is the standard pulse sequence when using T1-weighted images, which are commonly used to contrast tissues such as neural foramina and nerve roots. This is needed to decompress the nerves.

In all these body parts, the MRI is especially useful for looking at soft tissues. Lesions that affect the pedicles are a strong indicator of malignancy, while lesions of the facets are likely to be benign.
