Positron-Emission Tomography Clinical Trial
Official title:
68Ga-FAPI-LM3 PET/CT Imaging in Patients With FAP/SSTR2 Positive Disease and Compared With 18F-FDG
As a new dual receptor (SSTR2 and FAP) targeting PET radiotracer, 68Ga-FAPI-LM3 is promising as an excellent imaging agent applicable to SSTR2 positive diseases. In this research, we investigate the safety, biodistribution and radiation dosimetry of 68Ga-FAPI-LM3 in healthy volunteers. Moreover, we evaluate the potential usefulness of 68Ga-FAPI-LM3 positron emission tomography/computed tomography (PET/CT) for the diagnosis of lesions in SSTR2 positive diseases, and compared with 18F-FDG PET/CT.
As a new dual receptor (SSTR2 and FAP) targeting PET radiotracer, 68Ga-FAPI-LM3 is promising as an excellent imaging agent applicable to SSTR2 positive diseases In this research, we investigate the safety, biodistribution and radiation dosimetry of 68Ga-FAPI-LM3 in healthy volunteers. Moreover, subjects with SSTR2 positive diseases underwent contemporaneous 68Ga-FAPI-LM3 and 18F-FDG PET/CT for diseases assessment. Lesions uptakes were quantified by the maximum standard uptake value (SUVmax). The numbers of positive lesions of 18F-FDG and 68Ga-FAPI-LM3 PET/CT were recorded by visual interpretation. The diagnostic accuracy of 68Ga-FAPI-LM3 were calculated and compared to 18F-FDG PET/CT. ;
