  2. Perfusion MRI - Wikipedia

    en.wikipedia.org/wiki/Perfusion_MRI

    The common procedure for a DCE-MRI exam is to acquire a regular T1-weighted MRI scan (with no gadolinium), and then gadolinium is injected (usually as an intravenous bolus at a dose of 0.05–0.1 mmol/kg) before further T1-weighted scanning. DCE-MRI may be acquired with or without a pause for contrast injection and may have varying time ...

    en.wikipedia.org/wiki/In_vivo_magnetic_resonance...

    In vivo magnetic resonance spectroscopy (MRS) is a specialized technique associated with magnetic resonance imaging (MRI). [1] [2]Magnetic resonance spectroscopy (MRS), also known as nuclear magnetic resonance (NMR) spectroscopy, is a non-invasive, ionizing-radiation-free analytical technique that has been used to study metabolic changes in brain tumors, strokes, seizure disorders, Alzheimer's ...

    The field strength of the magnet is measured in teslas – and while the majority of systems operate at 1.5 T, commercial systems are available between 0.2 and 7 T. 3T MRI systems, also called 3 Tesla MRIs, have stronger magnets than 1.5 systems and are considered better for images of organs and soft tissue.

    For example, imaging of prostate tumors is better accomplished using T2-MRI and DWI-MRI than T2-weighted imaging alone. [7] The number of applications of mpMRI for detecting disease in various organs continues to expand, including liver studies, breast tumors , pancreatic tumors , and assessing the effects of vascular disruption agents on ...

    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 ...

  7. Type 3 diabetes - Wikipedia

    en.wikipedia.org/wiki/Type_3_diabetes

    Type 3 diabetes is a proposed pathological linkage between Alzheimer's disease and certain features of type 1 and type 2 diabetes. [1] Specifically, the term refers to a set of common biochemical and metabolic features seen in the brain in Alzheimer's disease, and in other tissues in diabetes; [1] [2] it may thus be considered a "brain-specific type of diabetes."

  8. Fast low angle shot magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Fast_low_angle_shot...

    Fast low angle shot magnetic resonance imaging (FLASH MRI) is a particular sequence of magnetic resonance imaging. It is a gradient echo sequence which combines a low-flip angle radio-frequency excitation of the nuclear magnetic resonance signal (recorded as a spatially encoded gradient echo) with a short repetition time .

    Higher signal for more water content [1] Low signal for fat in standard Spine Echo (SE), [1] though not with Fast Spin Echo/Turbo Spin Echo (FSE/TSE). FSE/TSE is the standard of care in modern medicine because it is faster. With FSE/TSE, fat has high signal due to disruption of hyperfine J-coupling between adjacent fat protons. [3]
