GAGG(Ce) scintillator crystals are useful in diverse applications such as:
Medical Imaging - PET, PEM, SPECT and CT
Specialist applications in high energy, nuclear, space and medical physics

GAGG(Ce) has best light output in all series of oxide crystal. Besides, it has good energy resolution, High density, non-selfradiation, Non- hygroscopic. It’s widely used in PET, PEM, SPECT, CT , X-ray &Gamma ray detection. 
Yttrium aluminium garnet Y3Al5O12:Ce (YAG:Ce) and Lutetium Aluminum Garnet activated by cerium (Lu3Al5O12:Ce, LuAG:Ce) are fast and bright scintillation materials. The decay time is 70-100ns. This is of advantage in time dependent and coincidence measurements. The wavelength of scintillation emission is about 530-550 nm, which is ideal for photodiode and avalanche diode readout. 
GAGG(Ce) is an ideal scintillation crystals, which is widely used in Nuclear medicine (Medical imaging system, such as Position Emission Tomography, PET, PET/CT, and SPECT scan system), Neutron sensor, Oil detection equipment and security inspection equipment.
