The technique of radionuclide studies of inflammatory processes in the heart

The work is devoted to verification of 99mTc-Pirfotechum SPECT combined with 99mTc-MIBI techniques for the diagnosis of myocarditis. Forty patients with persistent form of idiopathic atrial fibrillation underwent myocardial scintigraphy with 99mTc-Pirfotechum, combined with myocardial perfusion scintigraphy with 99mTc-MIBI. The obtained scintigraphic data were compared with the results of endomyocardial biopsies. In this work, we determined the sensitivity, specificity and diagnostic accuracy of this technique in the diagnosis of inflammatory changes in the myocardium in patients with idiopathic AF.
