Abstract

This study shows an example of the pronounced uptake of 99mTc-polyphosphate in the hand joints of a patient with rheumatoid arthritis. Bone-labelling and blood-labelling radio-isotopes, 18F and 113mln respectively, have been used to help establish, image-wise, the site of uptake in the joints. A comparison of the joint uptake of 99mTc-polyphosphate with that of 99mTc has also been made, and shows that 99mTc-polyphosphate is superior in this aspect. The use of 99mTc-polyphosphate as a joint agent is suggested.
