Willems et al. assessed the use of time-resolved whole-head CT angiography (4D-CTA) using a 320 detector row CT scanner in patients with brain arteriovenous malformation (AVM). Positive diagnosis was made possible in each of the 17 cases. Although some angioarchitectural details were missing, the accuracy seemed sufficient for AVM classification. The main benefit from 4D-CTA is the possibility to edit cross-sectional imaging (which undoubtedly enable better intranidal study), and perfusion maps opening the way to the analysis of surrounding tissues microcirculation. It appears obvious that 4D-CTA has a high potential for treatment planning as well as for follow-up
