The performances of 2 commercial gamma cameras, with crystals 1.3 and 0.6 cm thick, are compared. Phantom studies simulating clinical conditions showed no significant difference in performance at 140 keV. At 68 keV, the thinner crystal gave marginal improvements in camera performance with phantoms simulating clinical conditions. Frequent use with very low-energy emitters, such as Tl-201, would be needed to justify the expense required to refit the 1.3 cm camera with a 0.6 cm crystal.
