WebA SPECT tracer is currently available for accurate diagnosis of Parkinson’s disease. However, the small region in the brain that must be imaged requires a dedicated brain SPECT imager with special gamma cameras to provide high resolution, which adds to the cost of the procedure. WebThe SPECT tracer emits gamma radiation directly, as opposed to PET where the gamma radiation is emitted indirectly. Because SPECT does not use coincidence detection there is decreased resolution. SPECT is much less expensive than PET and uses longer lived and more variable radiolabeled tracers.
