Background: Fibroblast-activation protein (FAP) is an enzyme that appears in high numbers in certain cancer cells. \[18F\]FAPI-74 is a new tracer-a substance that is injected into a person s body before an imaging scan. Researchers believe that \[18F\]FAPI-74 may be able to highlight FAP enzymes more effectively than approved tracers. If so, the new tracer would make it easier to find FAP-positive tumors in the body. Objective: To see if \[18F\]FAPI-74 PET scans are as good or better than other methods for detecting certain cancers. Eligibility: People aged 18 years or older with cancer in 1 of these places: the ducts of the pancreas, liver, gallbladder, or small intestine; stomach; bladder; ovaries; or adrenal glands. They must be enrolled in an NIH treatment study for their cancer. Design: Participants will have 2 baseline scans: 1 with \[18F\]FAPI-74; 1 with an approved tracer. The \[18F\]FAPI-74 will be infused through a tube attached to a needle inserted into a vein. About 1 hour later, the participant will undergo 1 or more imaging scans. Within 1 week, participants will undergo the same scanning procedures with the approved tracer. If the baseline scan with \[18F\]FAPI-74 shows the tumors, scans with this tracer will be repeated when their regular treatment regimen calls for scans again. If the scans with the regular tracer also showed tumors, this scan will be repeated within the same week as the repeated \[18F\]FAPI-74 scans. If either type of scan showed no tumors, that scan will not be repeated. If the participant s cancer progresses within 2 years, both types of scan may be repeated. Follow-up calls will continue for 2 years.
