  • Title: Contrast-enhanced MRI in spinal arteriovenous malformations and fistulae before and after embolisation therapy.
    Author: Hasuo K, Mizushima A, Mihara F, Matsumoto S, Yoshida K, Yoshiura T, Masuda K.
    Journal: Neuroradiology; 1996 Oct; 38(7):609-14. PubMed ID: 8912313.
    Abstract:
    MRI was performed in six cases of spinal arteriovenous malformation (AVM) and arteriovenous fistula (AVF) before and after embolisation. Intramedullary and perimedullary AVMs showed marked vascular enhancement after embolisation. This was thought to reflect feeding vessel occlusion and correlated well with a favourable clinical outcome. In dural AVFs, contrast-enhanced studies were essential for the diagnosis, unenhanced images being nonspecific. After embolisation, enhancement of the spinal cord was reduced, although one case with a poor outcome showed persistent enhancement.
