What are problems from extravasation of radionuclide pharmaceutical?
1. False positive and false negative stress test results. 2. Radio pharmaceutical taken up by lymph nodes and if not recognized can falsely be labelled as suspicious for cancer.
Infiltration of Technetium into subcutaneous tissue-4 DM software post processing here.
Stress images are readable as there is no inflitration and is performed first in our institution.
EF is calculable by gated technique.
Polar maps and visual assessment shows no ischemia or infarct of significance.
QA raw data is very useful to identify there was subcutaneous infiltration as there was radionuclide uptake in right axillary lymph node and not be confused as cancerous uptake.
