Cardiovascular computed tomography and magnetic resonance are an important topic withinthe area of cardiovascular imaging in Brazil and in the world... We currently have two international societies dedicated specifically to these methods.The SCMR (Society for Cardiovascular Magnetic Resonance) was the first society to befounded and by the year 2000, it was already organizing the process of credentialing forthose dedicated to cardiovascular magnetic resonance... The SCCT (Society of Cardiovascular Computed Tomography) wasfounded shortly after, following the advances of the method, and in 2009, made availableits guidelines for better practice of the method... Some pioneering work of great international impact has been elaborated by Brazilians andwe managed, through this editorial, to draw attention to each one in their area. – The study conducted by Miller et al had one of the highestscientific impact and collaboration of three Brazilians, one of which was theprincipal investigator, and also had the largest number of patients included in thestudy by a Brazilian center... Published in The New England Journal ofMedicine, the authors concluded that computed tomography can identifythe presence and severity of coronary artery disease with good accuracy, but whenpositive, could not replace conventional coronary angiography... The first multicenter study validating this new technique todetect myocardial ischemia was recently published by Rochitte et al... This study reported high accuracyfor detecting meaningful stenoses associated with perfusion defects in the sameterritory evaluated by tomography when compared with the combination of invasivecatheterization with SPECT scintigraphy, and with a lower cost of radiation dose.Thus, this new method is able to diagnose hemodynamically meaningful stenoses orthose associate with a reduction of myocardial blood flow... The studies by Bittencourt et al demonstrated the prognostic potential of computed tomography insymptomatic patients with nonobstructive and obstructive coronary disease... However,Prazeres et al were able tosummarize in an unique way the potential of the technique for use in the emergencyroom, with potential of cost reduction for low-probability patients... Without a doubt, magnetic resonance is one ofthe best methods for quantification of myocardial fibrosis... When present, myocardialfibrosis is associated with increased mortality and worse prognosis... The Arquivos Brasileiros de Cardiologia function as a nationalthermometer and a main scientific channel reflecting this explosion of publications... Over the past decade, we observed an increasingnumber of review articles and original articles, which reinforces the impact of tomography and magneticresonance in current cardiovascular imaging... Finally, it is not possible to include all studies by Brazilian authors due to theincreasing number of publications in the area, but we are sure that we are entering anew era of cardiovascular imaging... The great development of technology applied tomedicine causes computed tomography and magnetic resonance to grow increasingly,changing day-to-day the impact on clinical practice.

Mentions: In parallel, when we perform a search on PubMed using the word "cardiac" and the MeSH(Medical Subject Headings) terms "computed tomography" and "magnetic resonance imaging",we find a sum of publications close to 45 thousand articles (44,711 articles) (Figure 2).
