Figures
- FIGURE 1.
Anterior-view 99mTc-stannous colloid image shows unexpected findings of significant kidney, bladder, cardiac blood- pool, and soft-tissue background activity indicating altered biodistribution as well as uptake in liver and spleen.
- FIGURE 2.
Whole-body anterior- and posterior-view 99mTc-MDP images show unexpected findings of significant kidney, bladder, cardiac blood-pool, gallbladder, and soft-tissue background activity.
- FIGURE 3.
Series of 4 anterior-view images over first 10 min after injection of 99mTc-mebrofenin in patient with normal liver function. Images show reduced liver uptake with no excretion into bile ducts and significant kidney, cardiac blood-pool, and soft-tissue background activity.
- FIGURE 4.
Saline chromatograms of 99mTc-MDP preparations for which 99mTc-pertechnetate was diluted with either normal saline (A) or 5% dextrose (B). Notice that preparation B contains radiopharmaceutical impurities that do not migrate with solvent front.
