Abstract |
The usefulness of sequential scanning, three and 24 hours after injection of 197Hg chlormerodrin in the detection of metastatic tumors of the brain has been demonstrated. The 24-hour scan was positive in 29% of the cases in which a metastatic lesion was suspected although the three-hour scan was negative, and the 24-hour scan also revealed additional masses in another 20%. The delayed scan helped to demarcate the actual location of the lesion in 24% of the cases in which the three-hour scan was graded merely suspicious. It is concluded that the addition of a 24-hour scan strongly reinforces the statistical accuracy of the 197Hg brain scan, and thus is of practical clinical importance.
