title: Thallium-201-technetium-99m parathyroid subtraction scintigraphy: dual channel acquisition or sequential imaging?
abstract: Parathyroid subtraction scintigraphy has been performed in 108 patients. In 41 cases scintigraphic findings are correlated with surgical and histologic results. Comparison of sequential data acquisition and dual channel acquisition has been made. As the results of these two protocols are comparable, we prefer the dual channel acquisition because of the smaller chance of introducing subtraction artefacts caused by patient movement.
