胸腰椎圧迫骨折におけるＭＲＩの限界 腫よう性と非腫よう性の鑑別における有用性について

Abstract

Magnetic resonance imaging has been increasingly used in recent years. Vertebral compression fractures in elderly patient are a common occurrence, and although most vertebral compression fractures are due to senile osteoporosis, the radiologist is often consulted by his colleagues to identify pathologic fracture due to an underlying malignancy.In this study, we evaluated MRI for differentiating benign from pathologic compression fractures.Both benign and malignant fractures produced mixed signal intensities on the MR images. It seems to be difficult to differentiate benign compression fractures of vertebral bodies from pathologic fractures which are associated with tumor.
