Synopsis

Keywords: Pelvis, CEST & MT

The therapies for ovarian cystadenoma and cystadenocarcinoma are different, thus the differential diagnosis of ovarian lesions is critical. The diagnostic efficacy increased with the use of DWI and DCE-MRI, but the differential diagnosis of cystic ovarian lesions is still a challenge. This study evaluates the diagnostic efficacy of 3D APTw MRI in the differentiation between cystadenoma and cystadenocarcinoma based on the analysis of the cystic regions. The results showed that APTw SIs had better diagnostic performance than ADC values and may be used as a noninvasive tool for differential diagnosis and therapy guidance.
