    en.wikipedia.org/wiki/Leukoaraiosis

    Axial T2 FLAIR sequence MR image of a middle-aged man with leukoaraiosis. MRI image: Leukoaraiosis in a 90-year-old patient with cerebral atrophy. Head CT showing periventricular white matter lesions. Leukoaraiosis is a particular abnormal change in appearance of white matter near the lateral ventricles. It is often seen in aged individuals ...

    English: Real-time MRI of a human heart (short-axis view) at 1.5 mm spatial resolution and 33 ms temporal resolution. The T1-weighted images were acquired with an RF-spoiled radial FLASH sequence (TR/TE = 2.2/1.4 ms, flip angle 8°, 15 spokes) at 1.5 mm resolution, 8 mm section thickness, and 33 ms acquisition time without ECG or respiratory ...

    en.wikipedia.org/wiki/Cardiac_magnetic_resonance...

    Initial attempts to image the heart were confounded by respiratory and cardiac motion, solved by using cardiac ECG gating, faster scan techniques and breath hold imaging. Increasingly sophisticated techniques were developed including cine imaging and techniques to characterise heart muscle as normal or abnormal (fat infiltration, oedematous ...

    A physician may recommend cardiac imaging to support a diagnosis of a heart condition. Medical specialty professional organizations discourage the use of routine cardiac imaging during pre-operative assessment for patients about to undergo low or mid-risk non-cardiac surgery because the procedure carries risks and is unlikely to result in the change of a patient's management.

  6. Diffusion-weighted magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Diffusion-weighted...

    Diffusion tensor imaging (DTI) is important when a tissue—such as the neural axons of white matter in the brain or muscle fibers in the heart—has an internal fibrous structure analogous to the anisotropy of some crystals. Water will then diffuse more rapidly in the direction aligned with the internal structure (axial diffusion), and more ...

  7. Leukodystrophy - Wikipedia

    en.wikipedia.org/wiki/Leukodystrophy

    The degeneration of white matter can be seen in an MRI scan and is used to diagnose leukodystrophy. Leukodystrophy is characterized by specific symptoms, including decreased motor function, muscle rigidity, and eventual degeneration of sight and hearing. While the disease is fatal, the age of onset is a key factor, as infants have a typical ...

  8. White matter - Wikipedia

    en.wikipedia.org/wiki/White_matter

    White matter is the tissue through which messages pass between different areas of grey matter within the central nervous system. The white matter is white because of the fatty substance (myelin) that surrounds the nerve fibers (axons). This myelin is found in almost all long nerve fibers, and acts as an electrical insulation.

    Modern 3 Tesla clinical MRI scanner.. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and abnormalities in the heart and blood vessels ...
