説明

The purpose of this study was to compare conventional T1-weighted imaging (T1-WI) and chemical shift fat-saturation T1-weighted imaging (fat-sat T1-WI) by a diagnosis of the bone metastases. Thirty-two patients (143 vertebrae) with non-neoplastic lesions (normal group) and 32 patients (82 vertebrae) with spinal metastases (metastatic group) were evaluated using both images. The signal intensity (SI) distribution of both groups regarding T1-WI provided various patterns, and the SI measurements were not significantly different between the two groups ; however, the metastases which were mixed, showed a low SI. Regarding fat-sat T1-WI, all non-neoplastic lesions had a low-intensity homogeneous appearance; however, the metastases were mixed to a high SI. The SI measurement data of the metastatic group was significantly higher than that of the normal group. In conclusion, fat-sat T1-WI was useful for evaluating the vertebral metastases. When fat-sat T1-WI demonstrated a mixed to high SI in patients suspected of having vertebral metastasis, Gd-DTPA enhancement was thought to be the problem.
