A total of 100 patients with malignant primary bone tumors around the knee in a hospital were selected. The pathological data of preoperative MR single excitation plane echo diffusion weighted imaging and postoperative samples were analyzed. ADC values of tumor parenchyma, peritumoral edema tissue, tumor necrosis site, normal muscle and bone marrow tissue were calculated. The corresponding ADC value was obtained, and the difference of ADC value between different tissues was statistically significant. The ADC value of tumor parenchyma was significantly higher than that of normal bone marrow tissue and normal muscle, but lower than that of tumor necrosis site and edema bone marrow tissue and edema muscle. It can be seen that the application of MR-SSEPI-DWI to calculate the ADC value can identify and analyze the tumor parenchyma, peritumoral edema, tumor parenchyma and tumor necrosis sites of malignant bone tumors, so as to provide a strong basis for subsequent chemotherapy and development.展开更多
文摘This paper mainly analyzes the value of ADC in the diagnosis of primary malignant bone tumors. A total of 100 patients with malignant primary bone tumors around the knee in a hospital were selected.

The corresponding ADC value was obtained, and the difference of ADC value between different tissues was statistically significant. The ADC value of tumor parenchyma was significantly higher than that of normal bone marrow tissue and normal muscle, but lower than that of tumor necrosis site and edema bone marrow tissue and edema muscle.
