Are Non-contrast MR Images enough for Detection of Fracture Levels Prior to Percutaneous Vertebroplasty in Patients with Osteoporosis?
We evaluated the detectability of painful vertebral compression fractures (VCFs) on different MRI protocols in 40 osteoporotic patients with thoraco-lumbar osteoporotic vertebral fractures. Five hundred and ten thoracic and lumbar vertebrae in 40 patients were evaluated. All patients underwent percutaneous vertebroplasty. Vertebral fractures were found in 126 (24.7%) of 510 vertebrae. Healed vertebral fractures were found in 33 (26.2%) of 126 vertebral fractures. Painful osteoporotic VCFs was found in 93 (73.8%) of 126 fractures. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of contrast-enhanced MR images, and the non-contrasted combined protocol (including T1-weighted, T2-weighted and STIR images) for the detection of painful osteoporotic VCFs were all more than 90%. Therefore, the non-contrasted combined protocol can be used for detection of painful osteoporotic VCFs prior to percutaneous vertebroplasty, unless there are conditions where contrast-enhanced MR is needed to rule out other causes of VCFs.
