Abstract

Color labeling and retrospective time-interval selection have been used to produce scintiphotographic images of the central blood flow in conjunction with the radionuclide cardiac flow study. The images are formed by integrating over time intervals, chosen retrospectively to include the entire right heart, lung, or left heart (levo) phase of the radionuclide bolus transit. This provides improved statistical delineation of the images, and also tends to produce an intensity modulation inversely proportional to the local volume flow rate. Selected composite images may then be recorded on Polaroid color film through colored filters to obtain color contrast between adjacent or overlapping areas of the images. Intensity modulation is used in the conventional manner within each monochrome image. The resultant image is easily interpretable and more informative than conventional sequential scintiphotos.
