OBJECTIVES This study sought to assess the prevalence and markers of left ventricular (LV) thrombus among patients with systolic dysfunction. BACKGROUND Prior studies have yielded discordant findings regarding prevalence and markers of LV thrombus. Delayed-enhancement cardiovascular magnetic resonance (DE-CMR) identifies thrombus on the basis of tissue characteristics rather than just anatomi...

El presente artículo señala la determinación social de imagen cinemática como causa directa analogía entre las diferentes artes durante el periodo Primera Vanguardia. En particular, se profundiza en reciprocidad expresiva del Cine y Poesía Nueva que confirman numerosas aportaciones teóricas prácticas, poeta ultraísta Guillermo Torre o cineasta surrealista Luis Buñuel. Asimismo, demuestra conven...

Background Changes in myocardial strain have been shown to precede onset of systolic dysfunction in patients with cardiomyopathy. Traditionally performed with echocardiography, acoustic windows can limit strain evaluation. Preliminary work has shown good agreement between myocardial strain derived from deformation field analysis at balanced steady-state free-precession (bSSFP) cine MRI and spec...

Six healthy volunteers and three patients with cardiac anomalies were studied in a comparison of segmented turboFLASH (fast low-angle shot) cine, a method of magnetic resonance imaging that permits an entire series of high-resolution cine images to be obtained in one breath hold, with standard cine. Segmented turboFLASH uses a gradient-echo sequence designed for short imaging times in combinati...

S everal well-established MR techmques are routinely used for evaluation of the heart and great vessels. Tl-weighted spin-echo images gated to the cardiac cycle provide black-blood images of the heart and vessels. Spin-echo images provide good anatomic detail, but imaging times are relatively long (approximately 5-7 mm, depending on the heart rate). In addition, the images are static: only a si...

UNLABELLED Cardiac PET combined with CT is rapidly expanding despite artifactual defects and false-positive results due to misregistration of PET and CT attenuation correction data-the frequency, cause, and correction of which remain undetermined. METHODS Two hundred fifty-nine consecutive patients underwent diagnostic rest-dipyridamole myocardial perfusion PET/CT using (82)Rb, a 16-slice PET...

Cine magnetic resonance imaging (cine MRI) was used to evaluate the cardiac structures and blood flow in congenital heart diseases with left-to-right shunts. Fifteen children with left-to-right shunts which were confirmed by echocardiography or angiography were investigated in the present study. Five children each had atrial septal defect, ventricular septal defect, and complete endocardial cus...

OBJECTIVE To evaluate if color-coded parametric images could help subjective visual analysis and improve interobserver agreement in the evaluation of segmental contraction (SC) in CMR. BACKGROUND Routine evaluation of SC in CMR remains mostly based on visual analysis of cine loops and subsequent interobserver variability remains a potential drawback. MATERIALS AND METHODS Three short axis c...
