Conclusion

Gated SPECT studies provide important information about cardiac function that is independent of perfusion data. This is permitted by the generalization of the nongated SPECT study to sample the data temporally. The benefits of this approach are accompanied by new technical and clinical challenges related largely to interaction of varying rates of sinus rhythm and the response of the computer system. Identification of potential technical limitations is important, as is recognizing for which patients gated SPECT acquisition may not be suitable. These considerations should be part of a quality program to assure the highest quality of gated SPECT images and optimize the clinical utility of this important new method of acquiring SPECT images.
