Objective: Several radiologic imaging techniques have been used to predict the effects of treatment on lumbar facet joint (LFJ) pain. However, there are no reports on the use of contrast-enhanced magnetic resonance imaging (MRI) in the management of LFJ pain. In the current study, we aimed to evaluate the clinical ability of contrast-enhanced MRI using gadolinium to predict treatment outcomes for LFJ pain.
Methods: : A total of 26 patients with LFJ pain were recruited and intraarticular corticosteroid injections were performed to each patient. The treatment outcomes were assessed using a numerical rating scale (NRS), and the enhancement of the LFJ and the grading for osteoarthritis were investigated independently by two radiologists.
Results: Intraarticular corticosteroid injections were administered to 26 patients (12 women and 14 men; mean age: 65.19±11.05 years) with LFJ pain. Among the 26 patients, 16 patients were included in the enhanced group, and the remaining 10 patients were included in the non-enhanced group, based on contrast-enhanced MRI scans using gadolinium. In both the enhanced and non-enhanced groups, NRS scores significantly decreased at 1, 2, and 3 months after treatment (p < 0.05). However, we saw no significant difference between the groups from pretreatment to three months after treatment (p > 0.05).
Conclusions: The routine use of contrast-enhanced MRI using gadolinium is not recommended in patients with LFJ pain. |
