Diffusion‐perfusion mismatch can be used to identify acute stroke patients that could benefit
from reperfusion therapies. Early assessment of the mismatch facilitates necessary …

The discovery that brain tissue could potentially be salvaged from ischaemia due to stroke,
has led to major advances in the development of therapies for ischemic stroke. In this …

Ischemic stroke is the most common cerebrovascular disease, and its diagnosis, treatment,
and study relies on non-invasive imaging. Algorithms for stroke lesion segmentation from …

The warm and generous acceptance of earlier editions of this book and the advances that
have occurred in the neurosciences in the last few years have prompted the preparation of …

MR perfusion imaging is becoming an increasingly common means of evaluating a variety of
cerebral pathologies, including tumors and ischemia. In particular, there has been great …

Background and Purpose—We evaluate associations between the severity of magnetic
resonance perfusion-weighted imaging abnormalities, as assessed by the hypoperfusion …

PET and MRI provide complementary information in the study of the human brain.
Simultaneous PET/MRI data acquisition allows the spatial and temporal correlation of the …

Background and Purpose—We sought to assess whether the volume of the ischemic
penumbra can be estimated more accurately by altering the threshold selected for defining …

The goal of acute stroke treatment with intravenous thrombolysis or endovascular
recanalization techniques is to rescue the penumbral tissue. Therefore, knowing the factors …

Purpose To validate the use of perfusion computed tomography (CT) with whole-brain
coverage to measure the ischemic penumbra and core and to compare its performance to …
