The Application Of Ultrasonography In The Diagnosis Of The Musculoskeletal Tumor

Objective: To evaluate the diagnostic value of ultrasonography in bone tumors. Aimed at the application of ultrasound technology in the diagnosis of benign and malignant bone tumor to make an objective assessment.Methods:Nineteen patients with malignant bone tumors and fourteen with benign ones were examined with two-dimensional ultrasound (2DUS)and the Color Doppler Flow Imaging(CDFI). The echo character ,distribution of blood flow and hemodynamic changes of blood flow in the lesions were observed,and contrasted to postoperative pathological results. The description of 2DUS included the appearance,margins,interior echo,soft tissue around destroyed spine.Observation focused on the situation of bone destruction, with or without elevation of tumor and the continuity of cortical bone destruction, periosteal thickening up . Then observe the CDFI and CDE of internal tumors, peripheral blood, as well as for peripheral vascular lesions and the relationship between tumor grade color flow situation, the information obtained by an analysis of research. Detection of blood flow parameters including peak systolic velocity(PSV), end-diastolic velocity(EDV), resistance index(RI), and pulsatility index(PI).Results:Bone destruction, periosteal reaction, soft tissue masses in the two-dimensional images clearly show. CDFI can clearly show the tumor and the surrounding blood flow within the distribution of malignant peak systolic velocity (PSV), end diastolic velocity (EDV) than benign tumors (P<0. 05); resistance index (RI), pulsatility index (PI) of benign and malignant difference between the two groups was not significant, no statistical significance (P> 0.05), whereas RI and PI were not statistically different. 2DUS and color Doppler combined with the use of its diagnostic accuracy was 90.91% (30/33). Benign and malignant bone tumors of the continuity of cortical bone compared with soft tissue infiltration were significantly different. CDFI and CDE showed that benign and malignant bone tumor blood group classification case .CDFI also showed the discrepancy with statistical difference that thin color blood flow scattered around benign tumors, graded as 0-I (cases in present group made up 76.92%); vs sufficient blood supply for the malignant bone tumor mostly located inside the tumors and the surrounding intruded soft tissue, mainly graded as II-III (cases in present group made up 78.95%).Conclusion :Ultrasound soft tissue tumor of bone invasion has unique advantages to judge, CDFI of benign and malignant bone tumors in the differential diagnosis of a certain degree of significance.
