Abstract

Objective To explore the value of ADC in the differential diagnosis between benign and malignant tumors in the female pelvis. Methods DWI sequence was performed in 42 females with pelvic tumors proved by histopathology. The signal intensity on DWI and ADC values for tumors were analyzed. Results Benign tumors showed isoor hyper-signal intensity, while most malignant tumors showed hyper-signal intensity on DWI sequence. The mean ADC values for benign and malignant tumors were (1.55±0.48)×10-3mm2 /s and (1.23±0.37)×10-3mm2 /s, respectively. The difference of ADC value between two groups were statistically significant(P=0.023). Conclusion The signal intensity on DWI and ADC vale provide valuable information for differential diagnosis for pelvic tumors in female.
