Comparison of Quantitative Ventilation-Perfusion Lung Scan Results Using Different Xenon-133 Ventilation Images
Objective: This paper evaluates the influence of the specific Xe ventilation images used to calculate differential function in quantitative ventilation-perfusion lung scans. Methods: Whole-lung differentials were determined on 43 Xe ventilationfl mTc-macroaggregated albumin perfusion studies. Ventilation calculations were performed for the firstbreath, up to three equilibrium and the composite ...
متن کاملTechnical and analytical advances in pulmonary ventilation SPECT with xenon-133 gas and Tc-99m-Technegas.
This paper describes the recent advances in technical and analytical methods in pulmonary ventilation SPECT studies, including a respiratory-gated image acquisition of Technetium-99m (99mTc)-labeled Technegas SPECT, a fusion image between Technegas SPECT and chest CT images created by a fully automatic image registration algorithm, and a three-dimensional (3D). display of xenon-133 (133Xe) gas ...

متن کاملFlow Activation Studies Using Xenon-133 Clearance
Background and Purpose: Three mainstream strategies exist to detect the responses of regional cerebral blood flow to functional activation. We tested the significance of changes in raw regional cerebral blood flow data, regional cerebral blood flow data normalized by division by global cerebral blood flow (dependent model of the regional-to-global cerebral blood flow relation), and regional cer...
متن کاملContinuing Education Ventilation Scintigraphy
Ventilation scintigraphy is a well-established adjunct to perfusion lung imaging in the diagnosis of pulmonary thromboembolus (PE). Although PE may be diagnosed with a standard chest radiograph and perfusion scintigraphy, the findings may be largely nonspecific due to the many types oflung pathology that result in perfusion defects. The specificity of the perfusion (Q) study may be substantiall...
