In any case, there was no mortality signal associated with alteplase administered up to 24 hours after a stroke in HOPE.

For decades, scientists across the globe have investigated methods to accurately measure drug permeability across the ...

It will be shown that the ratio of this "apparent" rate and the true anatomic adipose perfusion rate (F A /F) can be used to quantitate the degree of diffusion limitation.

Perfusion-weighted imaging (PWI) provides semiquantitative information regarding CBF and identifies areas of hypoperfusion. Diffusion-weighted imaging (DWI) and quantified values of the apparent ...

The MRI protocol included diffusion-weighted imaging (DWI), as well as perfusion imaging (PWI), performed using dynamic susceptibility contrast imaging. This study is reported following the STARD ...
