ABSTRACT:
A radiological imaging method employing a contrast enhancement agent comprising stable xenon, oxygen and helium, for use with computerized two and three dimensional X-Ray systems and software used with said systems, in the imaging and quantitative measurement of pulmonary ventilation, patency of, distribution of and gas flow in the trachea, bronchi, bronchioles and alveoli, evaluation and optimization of respiratory therapy gas mixtures and pressures separately and in combination, liver blood flow, renal blood flow, cerebral blood flow and brain tissue function.
