Purpose: Diskography has recently regained popularity because of its potential in determining the symptomatic level in degenerative low back pain. The aim of this study was to compare diskography and CTdiskography findings with lumbar MRI and clinical findings and investigate the diagnostic value of diskography in degenerative low back pain of diskogenic origin.

Material and Methods: 11 patients (3 males, 8 females) with an age range of 14-58 were included in the study. Following clinical evaluation, lumbar MRI including Tl W and T2W axial and sagittal series, and diskography and CT-diskography of the lowest three lumbar disk levels were performed in all patients.

Results: Diskography was performed in 20 levels in 11 patients. In four patients (five levels) with disk degeneration on MRI and extravasation on CTdiskography, no diskogenic pain could be provoked on diskography. In the rest of the study group who alsa had diskogenic law back pain, disk degeneration and annular tears were detected on MRI and at least one of the injected levels was symptomatic on diskography.

Discussion: Initial results of our study, together with reports from literature suggests that diskography does not contribute to imaging of intervertebral disk disease and therefore, should not be used as a screening study. On the other hand, it is the single and most successful imaging modality in determining the symptomatic level in degenerative disk disease. Anahtar Kelimeler : CT-diskography, Diskography, MRI
