“…Several reasons for the occurrence of dark-banding artifacts are discussed. It is often considered to be a susceptibility effect because of its most frequent appearance during the arrival of the CM bolus in the ventricles (16,28). Other potential sources of origin may be bulk motion during sequence acquisition (29), limited spatial resolution (Gibbs ringing) (30), and/or a combination of these effects.…”

Purpose:To investigate the parallel acquisition technique sensitivity encoding incorporating temporal filtering (TSENSE) with three saturation-recovery (SR) prepared pulse sequences (SR turbo fast low-angle shot [SR-Turbo-FLASH], SR true fast imaging with steady precession [SRTrueFISP], and SR-prepared segmented echo-planar-imaging [SR-segEPI]) for semiquantitative first-pass myocardial perfusion imaging. Materials and Methods:In blood-and tissue-equivalent phantoms the relationship between signal intensity (SI) and contrast-medium concentration was evaluated for the three pulse sequences. In volunteers, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and normalized upslopes (NUS) were calculated from signal-time curves (STC). Moreover, artifacts, image noise, and overall image quality were qualitatively evaluated.Results: Phantom data showed a 40% increased linear range of the relation between SI and contrast-medium concentration with TSENSE. In volunteers, TSENSE introduced significantly residual artifacts and loss in SNR and CNR. No differences were found for NUS values with TSENSE. SR-TrueFISP yielded highest SNR, CNR, and quality scores. However, in SR-True-FISP images, darkbanding artifacts were most pronounced. NUS values obtained with SR-TrueFISP were significantly higher and with SR-segEPI significantly lower than with SR-TurboFLASH. Conclusion:Semiquantitative myocardial perfusion imaging can significantly benefit from TSENSE due to shorter acquisition times and increased linearity of the pulse sequences. Among the three pulse sequences tested, SRTrueFISP yielded best image quality. SR-segEPI proved to be an interesting alternative due to shorter acquisition times, higher linearity and fewer dark-banding artifacts.

“…High spatial resolution is another important factor that must be taken into consideration due to the necessity to discern between the subendocardial and subepicardial myocardium. 52 The main disadvantages of this technique include the MRI breath-holds sequence, time examination, contrast agent, adverse reactions, and costs. Renal disease represents another limitation of MRI, due to the risk of systemic nephrogenic fibrosis (if eGFR <30 mL/min/1.73 m 2 ).…”

For a better assessment of ischemic heart diseases, myocardial viability should be quantified. Current studies underline the importance and the evolution of several techniques and methods used in the evaluation of myocardial viability. Taking into account these considerations, the aim of this manuscript was to present the recent points of view regarding myocardial viability and its clinical significance in patients with ischemic cardiomyopathies and left ventricular dysfunction. On the other hand, the manuscript points out the role of magnetic resonance imaging (MRI), one of the most useful noninvasive imaging techniques, in the assessment of myocardial viability. By comparing the advantages and disadvantages of cardiac MRI, its usefulness can be better appreciated by the clinician. In the following years, it is considered that MRI will be an indispensable imaging tool in the assessment of ischemic heart disease, guiding interventions for revascularization and long-term risk stratification in patients with stable angina or myocardial infarction.

“…Excepto en los casos secundarios a una estenosis coronaria severa, los defectos de perfusión producidos por isquemia miocárdica únicamente se pueden detectar bajo condiciones de estrés 5 . El empeoramiento de la contracción miocárdica en las fases sucesivas del estudio tras el estrés farmacológico confirma la presencia de enfermedad arterial coronaria hemodinámicamen-te significativa.…”

RESUMENLa enfermedad cardiovascular es la causa más frecuente de mortalidad en los países desarrollados y constituye un grave problema social, económico y sanitario. Aunque existen muy diversas técnicas útiles para diagnosticar las enfermedades cardíacas, con frecuencia es preciso realizar más de una prueba para llegar a un diagnóstico concreto. La resonancia magnéti-ca es una técnica inocua, bien tolerada y segura que actualmente se encuentra disponible en la mayoría de los centros hospitalarios. Esta técnica permite estudiar en una única exploración la anatomía del corazón y valorar de forma cualitativa, semicuantitativa y cuantitativa los parámetros de función cardíaca. Es útil para el estudio de las enfermedades valvulares, miocardiopatías y de la enfermedad pericárdica. Aporta información de la anatomía y función cardíaca y vascular en las cardiopatías congénitas complejas. Además, con la administración de contraste intravenoso, permite conocer la viabilidad miocárdica en la cardiopatía isquémica. Por tanto, la resonancia magnética cardíaca se perfila como una de las técnicas más prometedoras para el estudio de la patología cardíaca congénita y adquirida. Palabras clave. Resonancia magnética.

Although very diverse, useful techniques exist for diagnosing cardiac diseases, it is frequently necessary to ask for more than one test to reach a specific diagnosis. Magnetic resonance is a harmless, well tolerated and safe technique, which is currently available in the majority of hospitals. This technique makes it possible in a single exploration to study the anatomy of the heart and to make a qualitative, semiquantitative and quantitative assessment of the parameters of cardiac function. It provides information of cardiac and vascular anatomy and function in complex congenital cardiopathies. Besides, with the administration of intravenous contrast, it enables knowledge to be gained of myocardial viability in ischaemic cardiopathy. Hence, cardiac magnetic resonance is emerging as one of the most promising techniques for the study of congenital and acquired cardiac pathology.
