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.
Diffuse axonal injury (DAI) is a brain injury in which scattered lesions occur over a widespread area in white matter tracts as well as grey matter. [1] [2] [3] [4 ...
SWI: Spoiled gradient recalled echo (GRE), fully flow compensated, long echo time, combines phase image with magnitude image [12] Detecting small amounts of hemorrhage (diffuse axonal injury pictured) or calcium. [12] Inversion recovery Short tau inversion recovery: STIR: Fat suppression by setting an inversion time where the signal of fat is ...
Intracranial hemorrhage (ICH), also known as intracranial bleed, is bleeding within the skull. [1] Subtypes are intracerebral bleeds (intraventricular bleeds and intraparenchymal bleeds), subarachnoid bleeds, epidural bleeds, and subdural bleeds. [2] Intracerebral bleeding affects 2.5 per 10,000 people each year. [1]

LONG ISLAND (PIX11) – It was the happiest day of Tunicia and Raleigh Hall's life. In what was nearly 30 years in the making, the Queens couple finally tied the knot on June 28. A month later ...
A pseudosubarachnoid hemorrhage is an apparent increased attenuation on CT scans within the basal cisterns that mimics a true subarachnoid hemorrhage. [1] This occurs in cases of severe cerebral edema , such as by cerebral hypoxia .
