MRI can be too sensitive for detecting degenerative changes and commonly displays pathology that is not necessarily responsible for the patient's symptoms. ⋯ HIZ is known to be a common lesion found using MRI in lower back pain patients. In operated segments, we found an incidence of 81.8% and in unoperated segments of 28.2%. Discography can discriminate between painful and non-painful discs. With the help of additional parameters such as contrast mean volume and pain characteristics during puncture, the number of false positive discograms can be reduced.
