Simplified Techniques for Radioangiographic Analysis
A variety of equipment is available and in use today that allows the formation of curves of activity as a function of time from selected cardiac chambers and lung fields in conjunction with the radionuclide cardiac-flow study. These radionuclide indicator-dilution (RID) curves can be analyzed to yield information about the hemodynamic status of cardiopulmonary circulation. In this study, RID curves were obtained from a scintillation camera, interfaced to a small on-line computer, and studies were performed pre- and postoperatively on patients undergoing heart surgery. The results from the preoperative studies have been compared with cardiac catheterization data which were available in every case.
