[Non-invasive imaging techniques of the coronary tree].
The technological development has made it possible to effectively evade the difficulties involved in the non-invasive study of the coronary tree, which is its small diameter and continuous movement. Improvement in the spatial and temporal resolution of the cardiac multidetector computed tomography has made it possible to incorporate this technique into the diagnostic armamentarium of coronary disease, with better results than the conventional tests. Its principal limitation is the need to use contrast and ionizing radiation. The cardiac magnetic resonance makes it possible to visualize the proximal coronary origins and segments without needing to use contrast or radiation. This makes it a reference technique in experienced sites when there is suspicion of a coronary abnormality, even as a <<verification>> technique in at risk populations, giving that it is innocuous.
