The recent reports confirm the idea that the selection of cerebral stroke p
atients for thrombolysis should be performed by MRI. These studies suggeste
d that DWI PWI MRA may be able to identify patients who are most likely to
benefit from thrombolytics, and that the PWI > DWI pattern in particular is
associated with an improved outcome from thrombolytic therapy. However, ma
ny questions remain unanswered and a lot of work is necessary before MRI gu
ided thrombolysis in acute cerebral stroke becomes a part of the standard c
are. (C) 2001 Elsevier Science Ireland Ltd. All rights reserved.
