From 11th international annual meeting of the German Society of Nuclear Medicine; Athens, Greece (24 Sep 1973). Rubidium-81 is a new myocardial imaging agent with an ideal T/sub 1/2 of 4.6 hr and energies acceptable for gamma-camera viewing. The target-to-nontarget ratio for heart image to background in the projection images is usually less than 2: 1, thus good statistics are necessary to delineate lesions. The low radiation dose and availability of this isotope allow one to obtain 6 to 10 times the data, and /sup 81/Rb is probably superior to /sup 129/Cs and /sup 43/K for myoca rdial imaging if adequate collimation is present.
