Abstract:
Objective To discuss the application value of diffusion weighted imaging(DWI)in the diagnosis and treatment of synovial sarcoma.Methods 48 patients with synovial sarcoma were selected.All patients were given conventional magnetic resonance imaging (MRI)and DWI detection examination,DWI diffusion sensitive factor examination was 500 s/was(b).All the patients'imaging results and disease detection were analyzed.ROC curve was used to analyze the value of DWI,MRI examination in the diagnosis of synovial sarcoma.Results DWI examination detection of synovial sarcoma was much higher than that of MRI,the difference was statistically significant(χ2 =5.62, P <0.05).ROC curve analysis showed that MRI examination in the diagnosis of synovial sarcoma specificity was 72.58%,sensitivity was 79.12%,the accuracy was 86.82%,DWI examination in the diagnosis of specificity was 76.81%,sensitivity was 85.79%,the accuracy was 95.18%.The sensitivity,specificity and accuracy of DWI were significantly higher than conventional MRI,the differences were significant(χ2 =5.72,5.68,5.12,all P <0.05). Conclusion DWI can effectively improve the detection rate of synovial sarcoma,and has higher diagnostic sensitivity, specificity and accuracy,it's conducive to the physician for treatment in a timely manner,and worthy of further clinical promotion.
