OBJECTIVE
To compare conventional T1-weighted imaging (SE-T1) and chemical shift fat-saturation T1-weighted imaging (FS-T1) in the diagnosis of bone metastases.
SUBJECTS
Twenty-two patients (101 vertebrae) with non-neoplastic lesions (Group 1) and 21 patients (72 vertebrae) with spinal metastases (Group 2) were evaluated with both images.
RESULTS
The signal intensity (SI) distribution of Groups 1 and 2 on SE-T1 showed various patterns, and SI measurement was not significantly different between the two groups. On FS-T1, all non-neoplastic lesions had a low-intensity homogeneous appearance; however, the metastases had mixed to high SI. The SI measurement data of Group 2 was significantly (P < 0.0001) higher than that of Group 1.
CONCLUSION
FS-T1 was useful in evaluating vertebral metastases.
目的
比较常规T1加权成像（SE-T1）和化学位移脂肪饱和T1加权成像（FS-T1）在骨转移瘤诊断中的应用。
研究对象
对22例患有非肿瘤性病变的患者（101个椎体）（第1组）和21例患有脊柱转移瘤的患者（72个椎体）（第2组）均采用这两种成像方式进行评估。
结果
第1组和第2组在SE-T1上的信号强度（SI）分布呈现出多种模式，两组间的SI测量值无显著差异。在FS-T1上，所有非肿瘤性病变均表现为低强度均匀外观；然而，转移瘤的SI则为混合至高信号。第2组的SI测量数据显著高于第1组（P < 0.0001）。
结论
FS-T1有助于评估椎体转移瘤。
