Title: Attenuation of radionuclide activity by metal-cup arthroplasties

Journal Article · · AJR, Am. J. Roentgenol.; (United States)
;

The half-value layers of stainless steel, bone cement, and polyethylene were measured for /sup 99m/Tc, /sup 67/Ga, /sup 111/In, and /sup 201/TI to render some insight into the attenuating effects of the metallic cup and other components used in surface-replacement revision arthroplasty. On theoretic consideration, a twofold increase in /sup 99m/Tc-methylene diphosphonate in bone inside the cup should not be attenuated to the point of escaping detection on the radionuclide images of the hip. /sup 67/Ga, using the 184 and 300 keV peaks, and /sup 111/In have greater half-value layers than /sup 99m/Tc and are subject to less attenuation by the metallic cup.
