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.
