Present and future of nuclear cardiology. Where we come from and where we are going.

The present of nuclear cardiology techniques with gated-SPECT, positron emission tomography, cardiac magnetic resonance, cardiac mIBG scintigraphy and anatomical and functional images of three-dimensional SPECT-CT fusion may be the future for some centers, a future more or less distant for others. The prediction of the ways that will be followed by the different radioisotope scans in the field of cardiology is to some extent uncertain and depends on the development of other noninvasive techniques and on the possibility of reducing the dose of irradiation, decreasing the undesirable effects of ischemia-inducing drugs, but also on the evolution of macroeconomics in different countries, and of course on the level of experience and excellence in nuclear cardiology laboratories and the confidence generated on clinical cardiologists.
