Popis: The current study is aimed to prepare 99mTc-lidocaine as a new myocardial perfusion-imaging agent. The used 99mTc was obtained from Al–99Mo-molybdate(VI) gel matrix. 99mTc-lidocaine showed higher (15.4 ± 0.11% ID/g) and faster (15 min post injection) cardiac uptake than the recently studied 99mTc-valsartan and 99mTc-procainamide. Consequently, 99mTc-lidocaine will be a valuable myocardial SPECT agent for diagnosis of emergency patients. Besides, the receptor affinity study confirmed the selectivity of 99mTc-lidocaine for sodium channels in the heart.
