GA-68 FAPI

About Ga-68 FAPI PET CT

Ga-68 FAPI PET CT is a specialized nuclear medicine imaging examination that uses a Gallium-68 labelled fibroblast activation protein inhibitor (FAPI) radiotracer to evaluate fibroblast activation protein expression in tissues. It combines functional PET imaging with anatomical CT imaging to provide information about tracer uptake and distribution.

FAP is expressed by activated fibroblasts, including cancer-associated fibroblasts, and FAPI PET imaging is being used for evaluation of selected cancers and other conditions involving fibroblast activation when clinically indicated.

What Does Ga-68 FAPI PET CT Evaluate?

This examination evaluates the distribution and uptake of the Ga-68 FAPI radiotracer in areas showing fibroblast activation protein expression. It can provide functional information about lesions and tissues with increased FAP-targeted tracer uptake.

The findings may be correlated with the patient's symptoms, medical history, pathology, laboratory results and other imaging investigations.

Why Is Ga-68 FAPI PET CT Performed?

Doctors may recommend Ga-68 FAPI PET CT when FAP-targeted molecular imaging is clinically appropriate. It may be considered for selected cancers and other conditions where assessment of fibroblast activation can provide additional diagnostic information.

FAP PET imaging can be used in selected settings for disease staging, restaging, assessment of treatment response and evaluation of whole-body target expression. The exact indication depends on the patient's condition and the treating specialist's clinical assessment.

How Is Ga-68 FAPI PET CT Performed?

The prescribed Ga-68 FAPI radiotracer is administered under the supervision of the nuclear medicine team. After an appropriate uptake period, PET and CT images are acquired using the PET CT scanner.

The patient needs to remain as still as possible during image acquisition. The nuclear medicine team provides instructions regarding tracer administration, positioning and scan timing.

The duration of the examination may vary depending on the prescribed protocol and clinical requirements.

Preparation for Ga-68 FAPI PET CT

Preparation requirements depend on the specific radiotracer and clinical imaging protocol. Patients should follow the instructions provided by the nuclear medicine team before the examination.

Patients should inform the nuclear medicine team about current medications, pregnancy or possible pregnancy, breastfeeding, previous nuclear medicine procedures and other relevant medical conditions before the scan.

Patients should not stop or change prescribed medicines unless specifically instructed by their treating doctor or nuclear medicine team.

Benefits of Ga-68 FAPI PET CT

Ga-68 FAPI PET CT provides functional information about fibroblast activation protein expression together with anatomical information from CT. This can help physicians identify and localize FAP-avid lesions throughout the body.

FAPI PET may provide additional information for disease assessment, staging, restaging and treatment-response evaluation in appropriate clinical settings. Its role continues to develop as clinical evidence expands.

Understanding the Ga-68 FAPI PET CT Report

The report may describe areas of increased or abnormal FAPI uptake together with relevant anatomical findings on CT. The significance of tracer uptake depends on its location, intensity, imaging characteristics and clinical context.

FAPI PET CT findings should be interpreted by a qualified nuclear medicine physician together with the patient's symptoms, pathology, laboratory results, treatment history and other relevant investigations.
