Ultrasonic imaging technique has advanced as important clinical examination for diagnosis of pathological processes within soft tissues.In this paper, significance of ultrasonic diagnosis of orthopedic diseases was discussed in comparison with clinical, radiological and pathological findings. The cases include benign or malignant tumor, tumorous condition, cyst, swelling and abscess in soft part, and additionally bone tumors.These tumors were scannd two-dimensionally with compound ultrasonic equipment. Sonic frequency is 2.25MHz. Ultrasonic displays of benign conditions were imaged as homologous transparent structure with clearly defined contour. In malignant tumors, multiple sonic reflection which showed abrupt linear pattern or spotted one were presented antithetically to benign conditions. These benign and malignant echo patterns were closedly analogous to tumor section and the finding at operation.Ultrasonotomographic displays received from different pathological processes give more useful diagnostic information in soft tissue diseases than that in bone tumors.On the other hand, ultrasonic visualisation of bone tumor enclosed in osseous structure does not prevail the roentgen diagnosis.
