The Nuclear Cardiology and Cardiac CT group (NCT) is equipped by one of two cadmium-zinc-telluride SPECT cameras in the Czech Republic. The NCT focuses on new imaging protocols using cadmium-zinc-telluride technique in nuclear cardiology. The group successfully tested and published feasibility of low-dose myocardial perfusion protocol using 201-thallium. The research is currently focused on diagnostic and prognostic verification of this low-dose protocol. The group also plans to start imaging of myocardial sympathetic innervation using 123-iodine in patients with heart failure and performs multimodality imaging of myocardial viability in collaboration with Cardiovascular Magnetic Resonance group.
