1 Introduction Reading provides one of the most significant gateways to knowledge (Gabrieli, 2009) and is a critical skill in modern societiHowever, dyslexia affects approximately 5-17% of children, making it the most common learning disability (Shaywitz, 1998)Dyslexia is a developmental condition characterized by marked yet unexpected difficulty in learning to read despite sufficient ...

Quadrupole magnet

Quadrupole magnets, abbreviated as Q-magnets, consist of groups of four magnets laid out so that in the planar multipole expansion of the field, the dipole terms cancel and where the lowest significant terms in the field equations are quadrupoleQuadrupole magnets are useful as they create a magnetic field whose magnitude grows rapidly with the radial distance from its longitudinal axis..


Complexes of the element gadolinium (Gd) are the most widely used of all MR contrast agents Because of its unique electronic structure (described below), Gd is strongly paramagnetic Paramagnetism is an intrinsic property of certain materials to become temporarily magnetized when placed in an external magnetic fieldIn fact, Gd is one of only four elements that can be magnetized at room ...

Advantages of Susceptibility

In gradient echo magnetic resonance imaging (MRI), intravascular thrombi (IT) can appear as vascular susceptibility artifacts, linked to local presence of intra-arterial deoxyhaemoglobin, and called susceptibility vessel signs (SVS)..


INTRODUCTION Aortic valve stenosis is the most common cause of left ventricular outflow obstruction in children and adults; less common causes are subvalvular or supravalvular disease ()This topic will review the clinical features, diagnosis, and evaluation of valvular aortic stenosis (AS) []The pathogenesis, epidemiology, natural history, medical therapy, and percutaneous and surgical ...

MRI Flow compensation

To compensate the dephasing of flows at variable velocity (non-null acceleration), gradient lobes again have to be added on, resulting in longer TE and a reduced signal Flow compensation gradients can be used in any sequence requiring the suppression of these artifacts, except for phase contrast MRA..

Renal medulla

The renal medulla is the innermost part of the kidneyThe renal medulla is split up into a number of sections, known as the renal pyramidsBlood enters into the kidney via the renal artery, which then splits up to form the interlobar arteriThe interlobar arteries each in turn branch into arcuate arteries, which in turn branch to form interlobular arteries, and these finally reach the glomeruli..
