Xenon ventilation imaging using dual-energy computed tomography in asthmatics: initial experience.

PURPOSE To assess the feasibility of xenon ventilation computed tomography (CT) for evaluating ventilation abnormality in asthmatics. MATERIALS AND METHODS Twenty-two, stable asthmatics (M:F = 10:12; mean age, 57.6) were included. Single-phase, whole-thorax, dual-energy CT was performed using dual-source CT (Somatom Definition, Siemens) after subjects had… CONTINUE READING
