Clinical
Applications:
Diffusion
weighted sequences are sensitive to early stroke
and when combined with EPI FLAIR imaging, acute
stroke can be distinguishable from chronic stroke.
Differential diagnosis of acute stroke, due to
thrombus, within four hours of onset of symptoms
is critical information when planning thrombolytic
interventions. Diffusion Weighted Images when
combined with Dynamic EPI images can provide useful
information for predicting future stroke, a critical
factor in patient management.

"The
Diffusion techniques supplied with EchoPlus make
it the most powerful tool I have ever had at my
disposal as a neuro imager…"
"Diffusion
is critically useful in characterizing focal brain
masses. As an example, it has the ability to differentiate
tumor from abscess, tumor from infarction, and
arachnoid cysts from epidermoid cysts…"
"
Overall, EchoPlus has an enormous impact on the
day-to-day practice on neuro imaging at our hospital."

"The
biggest benefit of EchoPlus is being able to better
evaluate and diagnose strokes. We are now seeing
Diffusions and Perfusions that show when a patient
is at risk for cell death, which means we may
be able to save some brain tissue."
