This research study involves undergoing a diagnostic imaging procedure called positron emission tomography/magnetic resonance imaging (PET/MRI). This type of scan uses a powerful magnet and a special drug that emits a small but detectable amount of radiation to show detailed images of tumors. This study, will examine the diagnostic effectiveness of positron emission tomography/magnetic resonance imaging (PET/MRI), which will be the intervention. The study will compare the results of this scan to either the computed tomography (CT) or PET/CT that participants would normally undergo as a standard of care for high-risk endometrial cancer.~The research study procedures include a screening for eligibility and a single study visit.~Participants will undergo the PET/MRI in one study visit of approximately four hours.~It is expected that about thirty-three (33) people will take part in this research study.~The U.S. Food and Drug Administration (FDA) has approved the PET/MRI scanner as a diagnostic modality option for indications that include for high-risk endometrial cancer.
This study is investigating if positron emission tomography (PET)/Magnetic resonance imaging (MRI) is more effective than the currently used imaging modalities (computed tomography [CT], or PET/CT) for high-risk endometrial cancer.~The name of the intervention involved in this study is:~Positron Emission Tomography/Magnetic Resonance Imaging (PET/MRI)
