From 3rd symposium on sharing of computer programs and technology in nuclear medicine; Miami, Florida, USA (16 Jun 1973) In proceedings of third symposium on sharing of computer programs and technology in nuclear medicine. The introduction of Anger gamma camera systems, which are interfaced to dedicated mini-computers for performing very high count rate dynamic blood flow studies has added new dimensions to quantitative radioisotope angiocardiography. Given the ability to introduce a bolus of activity into the right or left atrium of the heart and acquire the radionuclide image data very rapidly for the following few seconds, it is possible to apply pulsatile modeling concepts to determine cardiac output, total, forward, and regurgitant ejection fractions, and end-diastolic and end-systolic volumes. The application of such a model to radioisotope angiocardiographic data is discussed. (auth)
