Ovarian tumors are the first cause of death in gynecological malignancies. Their histopathological and morphological patterns are complicated and variable

and can be categorized as benign

borderline and malignant. There is a considerable overlap in conventional imaging appearances of ovarian tumors

leading to a difficult diagnosis. Functional magnetic resonance imaging (FMRI) such as diffusion-weighted imaging (DWI)

dynamic contrast-enhanced MRI (DCE-MRI) and magnetic resonance spectroscopy (MRS) has been increasingly applied in the clinical diagnosis and study of ovarian tumors. Through probing into the changes of motion of water molecule

microvascular perfusion

and concentration of metabolites

FMRI can harvest the functional and metabolic information of ovarian tumors

and thus help diagnosing and differentiating ovarian tumors

making surgical plan

evaluating therapeutic effect

and monitoring tumor recurrence.
