| Abstract: | Background Simultaneous dual-radionuclide technetium 99m/thallium 201 scintigraphy can potentially produce perfectly aligned stress and
rest images in less time than conventional protocols. However, interradionuclide crossover limits diagnostic accuracy. Accordingly,
we evaluated99mTc and201Tl crossover in line and heart phantoms. |
