Clinical significance of the tail-like pattern in soft-tissue sarcomas on magnetic resonance imaging
Publikováno v:
Journal of Orthopaedic Science. 23:1032-1037
Background An infiltrating abnormal signal around soft-tissue tumors along the fascial, neurovascular, or musculature plane on magnetic resonance imaging (T2-weighted, gadolinium-enhanced T1-weighted, or short-tau inversion recovery) is recognized as

Background: Ultrasonography is useful for distinguishing between benign and malignant soft-tissue tumors. However, no study has focused on its usefulness in the differential diagnosis between low-grade and high-grade soft-tissue sarcomas. We conducte

Background Preoperative evaluation of the risk of surgery-related blood loss in malignant soft tissue tumor resection is difficult because of wide variations in histological subtype, malignancy, location, and size. Ultrasonography is useful for the e

Purpose Preoperative discrimination between benign and malignant soft tissue tumors is critical for the prevention of excess application of magnetic resonance imaging and biopsy as well as unplanned resection. Although ultrasound, including power Dop

Introduction We analyzed the findings of diffusion-weighted (DW) imaging using the single-shot fast spin-echo sequence in acute cervical cord injury and evaluated the usefulness of this method for predicting the prognosis. Methods Our patient group c

Lipoma and well-differentiated liposarcoma (WDLS) are two representative lipogenic soft tissue tumors that have similar clinical, radiological, and pathological characteristics. Accordingly, it is difficult to distinguish these tumors preoperatively.
