It is important to diagnose benign ovarian cystic lesions as early and correctly as possible because some types of lesions have malignant potential. The objective of our study is to investigate whether amide proton transfer (APT) imaging is useful for evaluation of benign ovarian cystic lesions. We compared the APT signal in three different benign ovarian cystic lesions using three different durations of presaturation pulse.
