If asked to choose between a brain that looked nice, or one that functioned well, most of us would choose the second. Furthermore, the ultimate importance of cerebral disease is that it affects brain function, not appearance. Yet clinical neuroimaging has been built around the practice of imaging brain structure. Why so? Because structural images are easier to acquire, and structure and function

2 Abstract A fast, two-coil pseudo-continuous labeling scheme is presented. The new scheme permits collection of a multi-slice subtraction pair in less than three seconds, depending on the subject's arterial transit times. The method consists of acquisition of both the control and tag images immediately after a labeling period that matches the arterial transit time. The theoretical basis of the...

In the diagnostic imaging two kinds of modalities can be differentiated. On one side the anatomical imaging, providing a very accurate visualization of the intern structures of the human body; and the functional imaging, which is aimed to quantify the physiological processes taking place inside the human body without influencing them. One of the most widely spread practices used for this purpos...

Regret is a cognitively mediated, multifaceted emotion engendered by thoughts of how things might have been better had we behaved differently. The causes, experience and behavioural impact of regret have been widely studied by psychologists. However, research into the neural basis of regret has been motivated primarily by economic approaches, which often reduce regret to such a simplistic const...

A number of recent functional imaging studies have identified brain areas activated during tasks involving episodic memory retrieval. The identification of such areas provides a foundation for targeted hypotheses regarding the more specific contributions that these areas make to episodic retrieval. As a beginning effort toward such an endeavor, whole-brain functional magnetic resonance imaging ...

Background Segmented balanced steady state free precession (bSSFP) cine imaging is the gold standard MRI technique for assessing ventricular systolic function. The image acquisition involves ECG gating and is ideally performed during breath-hold to reduce artifacts from myocardial and respiratory motion. Real-time radial imaging with parallel imaging technique GRAPPA reconstruction (radial GRAP...
