Investigation of MRI,CT and ultrasonography diagnostic value in ovarinoma malignant neoplasms

Objective To evaluate the values of MRI,CT and ultrasonography imaging in diagnosis of ovarinoma malignant neoplasms.Methods The findings of MRI,CT and ultrasonography of ovarinoma malignant neoplasms confirmed by surgery and pathology of 43 were analysed by double blinding method.Results In diagnostic characteristics of ovarinoma maligant,the sensitivity,specility and accuracy of MRI/CT/ ultrasonography were 91.30%/88.23%/73.52%,92.31%/90.48%/72.73% and 91.76%/87.5%/73.21%,there were not statistically sigificant between MRI and CT,but there were statistically significant between CT and Ultrasonography.The accuracy of MRI.CT and Ultrasonography was 82.23%,79.91%and56.3% in staging of malignant neoplasms there were not statically sigificant between MRI and CT,but there were statically sigificant between CT and ultrasonography.Conclusion Ultrasonography are useful for early diagnosis of ovarinoma maligant neoplasm.Because of interfering of gas of intestine,the use of Ultrasonography is restricted.CT images may show the size,rang and inner structure of the neoplasmsms.MRI can show the local neoplasms and extension of neoplasms clearly on multiplanes and angles.MRI is superior to other evaluation in staging of Ovarinoma Malignant Neoplasms.
