In scintigraphy, the detection of scattered photons degrades both visual image analysis and
quantitative accuracy. Many methods have been proposed and are still under investigation …

The normal pattern of the myocardial sympathetic innervation was studied in 15 subjects
using single photon emission computed tomography (SPECT) gamma scintigraphy with …

The authors have investigated standard SPECT techniques (rotating gamma cameras, multi-
hole collimators, and filtered backprojection reconstruction) for imaging astatine-211 …

We have evaluated SPECT and two planar imaging methods, geometric mean (GM) and
buildup factor (BF), for their potential to quantitate in vivo211At distributions in rat spinal …
