Magnetic resonance imaging in spondylitis and spondylodiscitis

Magnetic resonance imaging (MRI) is highly sensitive and specific for the d iagnosis of spondylitis and in that respect is superior to other radiologic methods. Its excellent morphological resolution allows early recognition o f pathologies and spread of the spondylitis. Affected vertebral bodies and discs reveal typical alterations in T1- and T2-weighted images; post-gadoli nium images are necessary to improve specificity. MRI helps to diagnose tumors and degenerative changes. Thus, MRI is the met hod of first choice in the diagnosis and surveillance of spondylitis and sp ondylodiscitis.
