Abstract
PURPOSE
Myxoid liposarcoma has a propensity to metastasize to bone. MRI is the preferred modality for detecting bone disease. We evaluated multiple MRI sequences to determine an optimal screening method.
METHODS
Whole body MRI was performed on all patients. The number and locations of metastases found by imaging and round cell component of the sites sampled were evaluated.
RESULTS
We found a total of 68 osseous lesions. Whole body MRI utilizing STIR only sequences decreased imaging time by 83.6% and demonstrated the lesions the best.
CONCLUSIONS
STIR sequences can be exclusively used during staging and screening of myxoid liposarcoma.
摘要
目的
黏液样脂肪肉瘤易于转移至骨骼。磁共振成像（MRI）是检测骨病的首选方式。我们评估了多种MRI序列以确定最佳筛查方法。
方法
对所有患者进行全身MRI检查。评估通过成像发现的转移灶数量及位置，以及所取部位的圆形细胞成分。
结果
我们共发现68处骨病变。仅使用短反转恢复（STIR）序列的全身MRI使成像时间减少了83.6%，并且对病变的显示效果最佳。
结论
STIR序列可专门用于黏液样脂肪肉瘤的分期和筛查。
