PET/MR Versus CECT Scans in Imaging Patients With Ovarian Cancer or Highly Suspected Ovarian Cancer

This trial studies how well positron emission tomography/magnetic resonance (PET/MR) versus contrast enhanced computerized tomography (CECT) scans work in locating ovarian cancer tumors in patients with known or suspected ovarian cancer. PET, MR, and CECT scans use different methods to create images of areas inside the body. This trial is being done to see if PET/MR scans may help doctors locate ovarian cancer tumors, predict how well these tumors may be removed during surgery, and predict how patients respond to platinum-based chemotherapies compared to standard of care CECT scans.

Inclusion Criteria: * Patients with ovarian cancer or highly suspected ovarian cancer who are eligible to undergo laparoscopic evaluation for resectability will be enrolled in the trial. * Patients who have estimated glomerular filtration rate (eGFR) \> 30. Exclusion Criteria: * Patients allergic to gadolinium. * Patients who have eGRF \< 30. * Patients with cardiac pacers. * Pediatric patients. * Greater than 400 pounds in weight. * Blood glucose (\> 200 mg/dl). * Pregnant women.
