Summary. Presented clinical cases show great potential of joint analysis of the electrical activity of the heart based on the MCG dats and perfusion images based on PET, particularly in difficult-to-diagnose cases, i. e. patients with non-informative results of routine tests. 3D reconstruction of the current density on the basis of the inverse problem solving is the most promising direction of magnetocardiographic data. analysis.

Key words: magnetocardiography, PET, inverse problem, CAD.

INTRODUCTION

Worldwide, coronary artery disease (CAD) is becoming pandemic [1]. Mortality from CAD is predicted to reach 23.4 million in 2030. Now days, chronic CAD s estimated to affect 16.8 million people in the United States; and 2.65 million people in the UK. CAD was the single most frequent cause of death in USA and Western Europe (about 1 in every 5 deaths).The estimated direct and indirect economic cost of CAD in the United States for 2009 is $ 165.4 billion. Moreover, in the developing world, particularly in Ukraine, prevalence of CAD is even higher and there is the tendency tends to affect people at a younger age and thus could negatively affect the workforce and economic productivity. The morbidity, mortality, and socioeconomic importance of CAD make its diagnosis and management fundamental for all practicing physicians [2].
