Effect of DiscoGel treatment of the intervertebral disc at MRI.

To determine the impact of ethanol gel chemonucleolysis (EGCh) on the radiological picture of the treated intervertebral disc, the relationship between the initial radiological status and the clinical status of the patient after EGCh treatment, and the optimal radiographic criteria for qualifying a patient for EGCh treatment. The study involved a group of 45 patients (25 men and 20 women) aged 23–68 years (46 ± 11) who underwent an EGCh procedure after qualification, radiography, and clinical questionnaire evaluation. The results showed a decrease in the size of the protrusion and Gadolinium-Enhanced (GI) zone in the treated intervertebral disc. The presence of a high-intensity zone (HIZ) on baseline magnetic resonance imaging was found to be a good predictor of the timing and outcome of treatment, and an increase in disc height was observed in adjacent segments. These findings suggest that EGCh is a promising treatment for spine diseases, and the HIZ on baseline magnetic resonance imaging can be used as a qualification criterion for this procedure. • New method of treating spine diseases called ethanol gel chemonucleolysis (EHC). • Decrease in the size of the protrusion, Gadolinium-Enhanced (GI) zone in the treated intervertebral disc. • HIZ zone on primary MRI was a good predictor of the timing and outcome of treatment.
