However, no study has focused on its usefulness in the differential diagnosis between low-grade and high-grade soft-tissue sarcomas. We conducted a retrospective study to determine the usefulness of the parameters of ultrasonograph and to develop a practical scoring system for distinguishing between high-grade and low-grade sarcomas %K Soft tissue tumor %K Diagnosis %K Ultrasonography %K High-grade sarcoma %K Low-grade sarcoma %K Malignancy %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5859456/
