Brief Summary:
This feasibility trial studies the use of gallium-68 (68Ga)-FAPI as the imaging agent for positron emission tomography (PET)/computed tomography (CT), collectively PET/CT, in patients with various cancers. PET uses a radioactive substance called 68Ga-FAPI, which attaches to cancer activated fibroblasts. The PET scanner takes pictures that capture where the radioactive drug is "lighting up" and attaching to tumor cells, which may help doctors recognize differences between tumor and healthy tissue. CT uses X-rays to make a picture of areas inside the body. Using 68Ga-FAPI in diagnostic procedures, such as PET/CT, may allow doctors to identify smaller tumors than standard imaging.

Condition or disease Intervention/treatment Phase
Cancer Drug: 68Ga-FAPI Procedure: Computed Tomography (CT) scan Procedure: Positron Emission Tomography (PET) scan Phase 2

Detailed Description:


To assess feasibility and biodistribution of PET imaging in malignancy using 68Ga-FAPI.


Patients receive 68Ga-FAPI intravenously (IV) and then undergo PET/CT approximately 1 hour later.

After completion of study, patients are followed up at 24-72 hours.

Arm Intervention/treatment
Experimental: 68Ga-FAPI PET/CT
Patients receive 68Ga-FAPI IV and then undergo PET/CT approximately 1 hour later.
Drug: 68Ga-FAPI

68Ga-FAPI is quinoline based PET radiopharmaceutical.

68Ga-FAPI is administered intravenously (IV)

Other Name: 68-Ga-Fibroblast activation protein inhibitor (FAPI)

Procedure: Computed Tomography (CT) scan
Participants will have a CT scan for attenuation correction and anatomic localization of PET data.

Procedure: Positron Emission Tomography (PET) scan
PET images will be acquired.

Primary Outcome Measures :
  1. Feasibility of 68Ga-FAPI PET [ Time Frame: 24 months ]
    Feasibility of 68Ga-FAPI PET/CT imaging will be done to assess patients with malignancy. Feasibility will be measured using Likert scale (1-non diagnostic; 5-excellent; anything 3 or more is diagnostic). The study will be feasible if > 50% of scans will have a score of 3 or more
