Seven patients showing a localized area of increased uptake (hot spot) on 99mTc sulfur
colloid liver scans are described. Four also had dynamic studies. In five patients the hot spot …

In three cases, irradiated regions of liver failed to concentrate Tc-99m-sulfur colloid. In two of
these three, imaging with Tc-99m-acetanilide iminodiacetic acid (IDA) agents within five …
