This clinical trial studies positron emission tomography (PET) imaging utilizing 18F-FSPG
[(S)-4-(3-[18F]Fluoropropyl)-L-glutamic acid], a glutamic acid derivative, to image patients
with ovarian cancer before undergoing surgery or transplant. Diagnostic procedures, such as
18F-FSPG PET, may help find and diagnose ovarian cancer and find out how far the disease has
spread.
