MRI is the best imaging tool for evaluation of uterine tumors, but conventional MRI diagnosis results are subjective. T2 mapping is an objective quantification technique under certain magnetic field. Here we compared T2 values of common benign and malignant tumors under different field strengths. We found that T2 value of benign lesions was significantly lower than those of malignant lesions under both 1.5T and 3.0T, while diagnostic performance of T2 value under 3.0T were higher than 1.5T. We concluded that T2 mapping can be an effective quantitative tool in distinguishing between benign and malignant tumors, especially under 3.0T MR.
