Abstract
A polystyrene resin, suitable for semi-solid gastric emptying studies, was rapidly (< 20 min) and conveniently prepared using commercially available reagents. Using the outlined procedure, Chelex-100 resin bound 99mTc with greater than 98% labeling efficiency. The resulting 99mTc Chelex-100 resin demonstrated excellent in vitro and in vivo stability. The clinical application of 99mTc Chelex-100 resin, mixed with oatmeal, was tested in normal subjects and in various patient groups, including diabetic autonomic neuropathy, pyloric obstruction, postoperative dumping syndrome and morbidly obese patients before and after gastroplasty.
