Educating physicians about ventilation-perfusion scanning as an alternative to CT for the diagnosis of pulmonary embolisms led to a 23 percent decrease in patient exposure, according to a study ...
Dual-Energy Computed Tomography is of significant clinical interest due to the possibility of material differentiation and quantification. In current clinical routine, primarily two materials are ...
MDCT pulmonary angiography is replacing the ventilation-perfusion lung scan to diagnose suspected pulmonary embolism in hospitalized patients, say researchers from Rhode Island Hospital in Providence.
To analyze radiation induced changes in Hounsfield units and determine their correlation with changes in perfusion and ventilation. Additionally, to compare the post-RT changes in human subjects to ...
NO SINGLE NONINVASIVE TEST for pulmonary embolism is both sensitive and specific. Some tests are good for “ruling in” pulmonary embolism (e.g., helical CT) and some tests are good for “ruling out” ...
CT imaging is a very good way to find pulmonary embolisms — sudden blockages of an artery in the lung, which can be fatal if not treated quickly. But a new analysis finds that the procedure might be ...
