AIMS We evaluated the influence of concomitant mineralocorticoid receptor antagonists (MRAs) on the safety and neurohumoral effects of a direct renin inhibitor in the ALiskiren Observation of Heart Failure Treatment (ALOFT) study. METHODS AND RESULTS Patients with stable New York Heart Association class II-IV heart failure (HF), plasma B-type natriuretic peptide (BNP) concentration >100 pg/mL...

BACKGROUND AND PURPOSE We compared two-dimensional time-of-flight magnetic resonance angiography (MRA) and duplex ultrasonography with arteriography for the detection of 70% to 99% stenoses at the carotid artery bifurcation (ie, surgical disease according to findings of the North American Carotid Endarterectomy Trial). METHODS Three blinded readers independently measured stenoses on MRA in 73...

BACKGROUND AND PURPOSE The purpose of this work was to review and compare published data on the diagnostic value of duplex ultrasonography (DUS), MR angiography (MRA), and conventional digital subtraction angiography (DSA) for the diagnosis of carotid artery stenosis. METHODS We performed a systematic review of published studies retrieved through PUBMED, from bibliographies of review papers, ...

Introduction: Contrast-enhanced MRA (CE-MRA) is a well-established methodology that accurately depicts vessel morphology in multiple vascular territories. In order to minimize the signal contribution from background tissues, a precontrast data set is typically subtracted from the post-contrast data set. Parallel acceleration techniques such as GRAPPA and SENSE are routinely used to improve spat...

BACKGROUND In patients with complex pulmonary stenosis or atresia, a detailed delineation of all sources of pulmonary blood supply is necessary for planning surgical and transcatheter procedures and usually requires diagnostic cardiac catheterization. The goals of this study were to determine whether gadolinium-enhanced 3D magnetic resonance angiography (MRA) can provide a noninvasive alternati...

BACKGROUND AND PURPOSE Different studies already demonstrated the benefits of 7T for precontrast TOF-MRA in the visualization of intracranial small vessels. The aim of this study was to assess the performance of high-resolution 7T TOF-MRA after the administration of a gadolinium-based contrast agent in visualizing intracranial perforating arteries. MATERIALS AND METHODS Ten consecutive patien...

Background and Purpose We compared two-dimensional time-of-flight magnetic resonance angiography (MRA) and duplex ultrasonography with arteriography for the detection of 70% to 99% stenoses at the carotid artery bifurcation (ie, surgical disease according to findings of the North American Carotid Endarterectomy Trial). Methods Three blinded readers independently measured stenoses on MRA in 73 v...

BACKGROUND AND PURPOSE Digital subtraction angiography (DSA) is the method of reference for imaging of dural arteriovenous fistula (DAVF). The goal of this study was to analyze the value of different MR images including 3D contrast-enhanced MR angiography (MRA) with a high temporal resolution in diagnostic and follow-up imaging of DAVFs. MATERIALS AND METHODS A total of 18 MR/MRA examinations...

MRA (Multilingual Report Annotator) is a web application that translates Radiology text and annotates it with RadLex terms. Its goal is to explore the solution of translating non-English Radiology reports as a way to solve the problem of most of the Text Mining tools being developed for English. In this brief paper we explain the language barrier problem and shortly describe the application. MR...

Highlights • Standard approaches for contrast-enhanced and non-contrast-enhanced MR Angiography will be reviewed in terms of methodology and clinical utility in an interactive setting co-presented by a radiologist and physicist. • Motivation and implementation of newer MRA approaches, including dynamic contrasenhanced MRA with a contrast bolus and balanced SSFP MRA with and without cardiac gati...
