We present and discuss the "dark cerebellar sign" in contrast to the well known "white cerebellar sign". The "white cerebellar sign" relates to a normal cerebellum which appears hyperdense in contrast to a pathological hypodense cerebrum on computer tomography (CT). We present a child with a "dark

Bone marrow contains fat and water. Using magnetic resonance (MR) T1-weighted images, fat appears light gray and water appears dark gray. Black or low signal structures include normal cortical bone, bone islands, hemosiderin deposits, calcification, ossification, metal artifact, gas, and foreign

BACKGROUND
Bright blood late gadolinium enhancement (LGE) imaging typically achieves excellent contrast between infarcted and normal myocardium. However, the contrast between the myocardial infarction (MI) and the blood pool is frequently suboptimal. A large fraction of infarctions caused by

The clinical presentation of posterior myocardial infarction is not always easy, not even for the cardiologist. In this article a 70-year-old woman who presented with chest pain is described. The electrocardiogram at presentation showed marked ST-segment depression in leads V(1) to V(5) and slight

OBJECTIVE
This study introduced and validated a novel flow-independent delayed enhancement technique that shows hyperenhanced myocardium while simultaneously suppressing blood-pool signal.
BACKGROUND
The diagnosis and assessment of myocardial infarction (MI) is crucial in determining clinical

It has been shown that the consumption of cocoa has a positive influence on a number of cardiovascular surrogate parameters such as arterial vasodilatation and a moderate decrease in blood pressure in humans. In the blood, a decrease in platelet aggregation and an increase in angiogenetic progenitor

We report a natural experiment that took place in a cardiac intensive care unit (CICU). We had been alerted to the possibility that sunny rooms would be conducive to better outcomes by our findings in the psychiatric unit, and by reports that depressed cardiac patients did less well than those in

BACKGROUND
This study evaluates a novel dark-blood late gadolinium enhancement (LGE) cardiovascular magnetic resonance imaging (CMR) method, without using additional magnetization preparation, and compares it to conventional bright-blood LGE, for the detection of ischaemic myocardial scar. LGE is

The aim of this review article is to summarize current knowledge of the pathophysiology underlying right ventricular failure (RVF), focusing, in particular, on right ventricular assessment and prognosis. The right ventricle (RV) can tolerate volume overload well, but is not able to sustain pressure

OBJECTIVE
Delayed enhancement MRI using fast segmented k-space inversion recovery (IR) gradient-echo imaging is a well established "bright-blood" technique for identifying myocardial infarction and is used as the reference standard sequence in this study. The purpose of this study was to validate a

BACKGROUND
"Takotsubo" cardiomyopathy (TTC) is a clinical disorder usually triggered by intense emotional and/or physical stress, characterized by reversible severe localized left ventricular wall dyskinesia, transient changes of ST segment, without significant coronary artery stenoses, that can

OBJECTIVE
To assess the diagnostic accuracy of T2 mapping for the detection of myocardial edema in acute myocardial infarction (AMI), and to compare this diagnostic accuracy with that of the current standard for myocardial edema imaging, which is T2w dark-blood TSE imaging.
METHODS
29 patients with

Atherosclerosis is a chronic disease that, from its origin to its ultimate complications, involves inflammatory cells, inflammatory proteins, and inflammatory responses from vascular cells. It has been demonstrated that cytokine activities are under neuroendocrine control, in part exerted
