  2. Perfusion MRI - Wikipedia

    en.wikipedia.org/wiki/Perfusion_MRI

    In Dynamic susceptibility contrast MR imaging (DSC-MRI, or simply DSC), Gadolinium contrast agent (Gd) is injected (usually intravenously) and a time series of fast T2*-weighted images is acquired. As Gadolinium passes through the tissues, it induces a reduction of T2* in the nearby water protons; the corresponding decrease in signal intensity ...

    Dynamic susceptibility contrast: DSC: Measures changes over time in susceptibility-induced signal loss due to gadolinium contrast injection. [32] Provides measurements of blood flow; In cerebral infarction, the infarcted core and the penumbra have decreased perfusion and delayed contrast arrival (pictured). [33] Arterial spin labelling: ASL

  5. Perfusion scanning - Wikipedia

    en.wikipedia.org/wiki/Perfusion_scanning

    There are different techniques of Perfusion MRI, the most common being dynamic contrast-enhanced (DCE), dynamic susceptibility contrast imaging (DSC), and arterial spin labelling (ASL). [11] In DSC, Gadolinium contrast agent (Gd) is injected (usually intravenously) and a time series of fast T2*-weighted images is acquired. As Gadolinium passes ...

    In contrast, expectorants lubricate your airway, which helps loosen up the mucus and make the secretions in your airway thinner. By loosening up the mucus, expectorants make your cough more ...

  9. MRI contrast agent - Wikipedia

    en.wikipedia.org/wiki/MRI_contrast_agent

    MRI contrast agents may be administered by injection into the blood stream or orally, depending on the subject of interest. Oral administration is well suited to gastrointestinal tract scans, while intravascular administration proves more useful for most other scans. MRI contrast agents can be classified [2] by their: Chemical composition
