Abstract:Objective To evaluate the performance indicators and their influence factors of SPECT/
CT (Single Photon Emission Computed Tomography/ X-Ray Computed Tomography) so as to ensure
the clinical usage of the instrument. Methods GE Discovery 670 SPECT/CT (16-slice spiral CT) was
detected in line with NEMA (National Electrical Manufacturers Association) standards from various
aspects, including SPECT, CT, uniformity and rotate center of co-registration fusion images and
other performance indicators. The data of quality control obtained from 2012 to 2015 were analyzed
retrospectively. Results The errors of the quality control results were within the scope of testing
standards. Conclusion Regular quality control, maintenance as well as analysis and calibration of
various performance indicators of SPECT/CT were an important approach to ensure its performance and
improve the quality of images.
