Preparation of 99mTc radiopharmaceuticals: the effect on radiochemical purity of using sodium chloride injection from plastic ampoules that have been exposed to light

Abstract

When 99mTc albumin nanocolloid, 99mTc macrosalb and 99mTc exametazime are prepared using sodium chloride injection from plastic ampoules that have been exposed to light, radiochemical purity is adversely affected. The other 99mTc radiopharmaceuticals tested are unaffected.
