Abstract
A detailed comparison was performed between the quality of cardiac images obtained using red blood cells labeled in vitro and in vivo [in humans]. Both methods gave cardiac images of high quality. The in vitro method resulted in subjectively superior images, better intravascular retention of injected radioactivity and a higher left-ventricle-to-background count ratio (P < 0.05). The differences in image quality and left-ventricular blood-pool activity were not great and the slight advantage of the in vitro method was offset by a somewhat more complicated preparative procedure. Both agents were suitable for radionuclide imaging of the cardiac chambers.This publication has 4 references indexed in Scilit:
