Abstract:
Objective To assess the diagnostic value of dynamic contrast enhanced MR imaging in predicting the efficacy of distinguishing benign from malignant soft tissue tumor Methods Dynamic contrast enhanced MR imaging was performed in 30 patients with pathologically confirmed soft tissue tumors The MR signal intensity of the ROI was plotted The slope value of the time intensity curve was analyzed Results There was significant difference between the slope value of benign and malignant lesions Based on the slope value of half minute, differentiation of benign from malignant lesions was possible with 90 9% of the sensitivity, 89 4% of the specificity, 83 3% of the positive predictive value and 94 4% of the negative predictive value Conclusion Dynamic contrast enhance MR imaging can correctly predict benignity or malignance of soft tissue tumors
