• La Resonancia Magnética con la administración de Gadolineo se considera el método ideal o número uno, para el diagnóstico de la fibrosis del miocardio (F.M).
• La FM es el resultado de una Serie de Enfermedades Cardiacas, produce endurecimiento del músculo del corazón, fallo cardíaco, arritmias y muerte súbita.
• La Resonancia Magnética cuantifica la extensión de la fibrosis, además, mide la fracción volumétrica extra-celular reflejada en el espacio intersticial, separa en el miocardio su parte celular y componente intersticial.
• La Resonancia Magnética es un método diagnostico inocuo, no invasivo, fácil de usar en la práctica clínica diaria, sin embargo, se necesita mayor investigación clínica, antes de que se vuelva el método rutinario de diagnóstico.

T1 mapping: characterisation of myocardial interstitial space
Insights Imaging. 2015 Apr; Volume 6 Issue 2: 189-202
Myocardial fibrosis is always present in end-stage heart failure and is a major independent predictor of adverse cardiac outcome. Cardiac magnetic resonance (CMR) is an imaging method that permits a non-invasive assessment of the heart and has been established as the “gold standard” for the evaluation of cardiac anatomy and function, as well as for quantifying focal myocardial fibrosis in both ischaemic and non-ischaemic heart disease. However, cardiac pathologies characterised by diffuse myocardial fibrosis cannot be evaluated by late gadolinium enhancement (LGE) imaging, as there are no reference regions of normal myocardium. Recent improvements in CMR imaging techniques have enabled parametric mapping of relaxation properties (T1, T2 and T2*) clinically feasible within a single breath-hold. T1 mapping techniques performed both with and without contrast enable the quantification of diffuse myocardial fibrosis and myocardial infiltration. This article reviews current imaging techniques, emerging applications and the future potential and limitations of CMR for T1 mapping.
