Answer

National Comprehensive Cancer Network guidelines recommend chest x-ray or CT, as clinically indicated, and ultrasound and/or abdominal/pelvic CT or magnetic resonance imaging (MRI), as clinically indicated. Positron emission tomography (PET)/CT scan or MRI may be indicated for indeterminate lesions, if the results will alter management. [17]

MRI can increase the specificity of imaging evaluation in cases where the ultrasound appearance of the lesion is indeterminate. [ 8 ] MRI is not definitive, however. On MRI, endometriotic cysts with enhanced mural nodules are a hallmark of ovarian cancer, but they may also be a feature of benign neoplasms and even inflammatory diseases. Large contrast-enhanced nodules on large endometriotic cysts in an elderly patient are more likely to indicate malignancy. [18]
