Abstract：Objective To strictly implement the stability tests of Positron Emission Tomography
Computed Tomography (PET/CT) so as to ensure the secure and stable operation of PET/CT equipment,
lower the failure rate, prolong the service span and reduce the maintenance costs of PET/CT equipment.
Methods According to the test phantoms and methods in NEMA NU 2-2001, the stability test of PET/CT
was explored in this paper from multiple aspects including the detector working state, spatial resolution
testing, sensitivity testing, SUV calibration and PET/CT image fusion accuracy testing. Results During
the process of PET/CT stability test, the unqualified item was timely corrected and the failure rate was
reduced so as to guarantee the quality of images. Conclusion The stability test of PET/CT could ensure
the image quality and reduce the failure rate.
