Diffusion- and perfusion-weighted MRI in therapeutic neurointerventional procedures

Cronqvist, Mats LU ; Ramgren, Birgitta LU ; Geijer, Bo LU ; Wirestam, Ronnie LU orcid ; Brandt, Lennart LU and Holtås, Stig LU (2001) In Neuroradiology 43(8). p.662-671
Abstract
We describe three patients in whom we used MRI, including diffusion- and perfusion-weighted imaging (DWI, PWI) in conjunction with endovascular therapy. Two had intracranial aneurysms and one an arteriovenous malformation (AVM). The aneurysms were treated by coil embolisation or detachable balloons for proximal artery occlusion; the AVM was obliterated by intranidal glue injection. All patients had transient or permanent neurological deficits after treatment. The MRI techniques and interventional procedures are described and the DWI and PWI patterns found are correlated with the clinical features. We discuss how the information gained from MRI may increase our understanding of procedure-related complications and its potential impact on our... (More)
