Study: NCT06421142

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: imaging examinations:FAPI PET/MRI, FDG PET/MRI, MRI
Description: FAPI PET/MRI and FDG PET/MRI examination Data acquisition was performed using a GE Healthcare SIGNA PET/MR instrument. Enrolled patients were injected intravenously with 68Ga-FAPI or 18F-FDG tracer and underwent simultaneous PET and MRI scanning approximately 30-60 minutes after intravenous administration of the tracer at a dose of 1.85-3.7 MBq/kg.~MRI examination MRI examination was performed using a Skyra 3.0T MRI scanner from Siemens, Germany, with a 16-channel phased-array surface coil, and the scanning range was from the superior margin of the iliac wing to the inferior margin of the pubic symphysis.
