First Outcomes of [[99mTc]Tc-DB15 in BC Sufferers Applying SPECT/CT three.6.1. Tolerability 3.6.1. Tolerability No adverse reactions have been recorded immediately after injection of [99mTc]Tc-DB15. The patients No adverse reactions were recorded just after injection of [99m Tc]Tc-DB15. The patients did not report any certain signs, the heart price and blood stress have been steady through and didn’t report any precise indicators, the heart rate and blood stress have been stable through and just after injection. No important modifications inside the hematology and biochemistry parameters right after injection. No substantial changes inside the hematology and biochemistry parameters were recorded any time point after the imaging. Patient 1 complained of intensified bone have been recorded atat any time point after the imaging. Patient 1 complained of intensified bone pain (CTCAE 1) quite a few hours just after immediately after the which on the other hand resolved following several discomfort (CTCAE gradegrade 1) a number of hours the scan, scan, which even so resolved after a number of and and w.
