  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 ...

    en.wikipedia.org/wiki/MRI_pulse_sequence

    Dynamic susceptibility contrast (DSC): Gadolinium contrast is injected, and rapid repeated imaging (generally gradient-echo echo-planar T2 weighted) quantifies susceptibility-induced signal loss. [45] Dynamic contrast enhanced (DCE): Measuring shortening of the spin–lattice relaxation (T1) induced by a gadolinium contrast bolus. [46]

    Dynamic susceptibility contrast: DSC: Measures changes over time in susceptibility-induced signal loss due to gadolinium contrast injection. [20] Provides measurements of blood flow; In cerebral infarction, the infarcted core and the penumbra have decreased perfusion and delayed contrast arrival (pictured). [21] Arterial spin labelling: ASL

  6. 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 ...

    An MRI did not reveal anything and a second PSA test remained high. A biopsy was ordered and in March it revealed early stage cancer. According to Mannix, Wojnarowski learned of the news just ...

  9. Susceptibility weighted imaging - Wikipedia

    en.wikipedia.org/wiki/Susceptibility_weighted...

    Susceptibility weighted imaging (SWI), originally called BOLD venographic imaging, is an MRI sequence that is exquisitely sensitive to venous blood, hemorrhage and iron storage. SWI uses a fully flow compensated, long echo, gradient recalled echo (GRE) pulse sequence to acquire images.
