ABSTRACT
PURPOSE:
The success of percutaneous vertebroplasty (PVP) depends greatly on preprocedural evaluation of the patients. The purpose of this study was to evaluate the efficacy of preprocedural magnetic resonance imaging (MRI) for the indications of PVP. MATERIALS ANDMETHODS:
A retrospective review of 122 osteoporotic compression fractures in 63 patients who underwent preprocedural gadolinium-enhanced MRI and PVP was performed. Based on the extent of contrast enhancement on preprocedural MRI, each case was classified into one of two groups group 1, which represented more than 50% of the vertebral body enhanced; and group 2, which represented less than 50% of the vertebral body enhanced. The most enhancing level was evaluated in multilevel PVP sessions. We evaluated the difference of pre- and postprocedural pain scales between groups 1 and 2 using Mann-Whitney's U-test.RESULTS:
There was a trend toward higher preoperative pain score in group 1, but it was not statistically significant (P = 0.0537). In addition, the postoperative pain score in group 2 was significantly higher than that in group 1 (P = 0.0007). The difference between the pre- and postoperative pain scores was significantly higher in group 1 than in group 2 (P = 0.0001).CONCLUSION:
Contrast enhancement on MRI indicates a painful lesion and extensive contrast enhancement predicts better pain relief after PVP.
