- FIG 1.
Boxplots showing HIR versus Calgary/Menon mFDCTA consensus scores (A) and HIR versus ASITN/SIR DSA consensus scores (B).
- FIG 2.
A–D, Patient with M1 occlusion (left) and good collaterals visualized (A) on pre-interventional mFDCTA (arterial phase, Calgary/Menon grade 4). Pre-interventional DSA (left: anterior-posterior view; right: lateral view) in the early arterial phase (B) and in a later venous phase (C) shows good leptomeningeal retrograde filling of the initial antegrade capillary blush deficit (target downstream territory, ASITN/SIR grade 4). D, Tmax perfusion maps on different levels that depict the low ratio of tissue with Tmax > 10 seconds (red) to Tmax > 6 seconds (green) (HIR = 0.2). E–H, Patient with M1 occlusion (left) and bad collaterals depicted (E) on pre-interventional mFDCTA (arterial phase, Calgary/Menon grade 2). Pre-interventional DSA (left: anterior-posterior view; right: lateral view) in the early arterial phase (F) and in a later venous phase (G) shows poor leptomeningeal retrograde filling of the initial antegrade capillary blush deficit (target downstream territory, ASITN/SIR grade 1). H, Tmax perfusion maps show the high ratio of tissue with Tmax > 10 seconds (red) to Tmax > 6 seconds (green) (HIR = 0.7).
- FIG 3.
Boxplots showing rCBF < 45% versus Calgary/Menon mFDCTA consensus scores (A) and rCBF < 45% versus ASITN/SIR DSA consensus scores (B). C, Scatterplot with HIR versus rCBF < 45%.
