Adverse reaction to 99Tcm sulfur colloid in a routine examination. A case report.

The case of a patient in whom an allergic reaction developed after injecting 99Tcm sulfur colloid for a routine liver scan is herein presented. Since this reaction did not appear when injecting the same patient 99Tcm polyphosphate for a bone scan, it can be assumed that the allergic reaction was due to the stabilizer.
