Abstract

No method applicable to patients is presently available for accurate visualization and quantitative measurement of the fundatamental determinants of cardiovascular and respiratory function; namely, the full temporal and spatial distribution of myocardial and pulmonary dynamics, and the spatial distribution and magnitude in all regions of the heart and lungs of blood flow, upon which myocardial and pulmonary dynamics depend. However, the availability of heretofore unattainable capabilities for measurment of cardiac, pulmonary, and circulatory dynamics is now on the horizon, and is based on the development of high temperal resolution, three-dimensional, whole-body computed tomography systems. Dynamic spatial (3-D) computed tomography offers the potential for measurement in the intact throax of the instant-to-instant regional changes in shape and dimensions of the heart and lungs and of the spatial distribution of myocardial and pulmonary blood flow, which are the fundamental determinants of cardiopulmonary function and reserve. In addition, dynamic spatial computed tomography of the heart will facilitate more accurate diagnostic assessment of the localization, extent, and nature of cardiovascular abnormalities and pathology such as coronary artery disease, myocardial ischemia, and myocardial infarction.
