High-energy (511-keV) imaging with the scintillation camera
A dual-head scintillation camera has been adapted for high-energy (511-keV) imaging by extending the useful energy range and linearity maps to 560 keV, implementing high-energy sensitivity maps, and developing high-energy collimators. High-energy parallel-hole collimators have inferior spatial resol...

| description | A dual-head scintillation camera has been adapted for high-energy (511-keV) imaging by extending the useful energy range and
linearity maps to 560 keV, implementing high-energy sensitivity maps, and developing high-energy collimators. High-energy
parallel-hole collimators have inferior spatial resolution and sensitivity relative to the low-energy, high-resolution collimators
commonly in use. With high-energy parallel-hole collimators, phantom studies show that the limit for detectability of "hot"
lesions is 1.5 cm and 1.3 cm in diameter or larger for 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FDG) uptake ratios of 5:1
and 10:1, respectively, if one assumes adequate counting statistics. Dual-isotope, single-acquisition techniques for using
technetium-99m methoxy isobutyl isonitrile and FDG have been developed and proved useful in identification of ischemic but
viable myocardium. High-energy fan-beam collimators have superior spatial resolution but inferior sensitivity relative to
low-energy, high-resolution collimators. Metabolic images of the brain obtained with FDG demonstrate spatial resolution comparable
with that of positron emission tomography, but such studies are often limited by inadequate counting statistics. |
