Figures
- Fig 1.
3D proton-density-weighted vessel wall source image (A), black-blood luminal angiography (B), TOF-MRA (C), and CTA (D) all depict moderate stenosis of the left M1 MCA (arrow). The 3D vessel wall image (A) shows eccentric plaque (arrow) on the MCA wall. The inset is a magnified vessel wall image. These images are used as source images to generate luminal angiography with a minimum intensity projection.
- Fig 2.
CTA (A) and black-blood luminal angiography (B) depict severe stenosis of the left M1 MCA (arrow) and arteries distal to the stenosis. C, TOF-MRA overestimates this severe stenosis as an occlusion (arrow) and fails to show the distal arteries. D, The 3D vessel wall image shows severe stenosis of the MCA and eccentric plaque (arrow) on the vessel wall.
- Fig 3.
DSA (A) and CTA (B) depict severe stenosis of the left M1 MCA (arrow). C, TOF-MRA overestimates this severe stenosis as an occlusion (arrow). Both the 3D vessel wall image (D) and black-blood luminal angiography (E) depict this severe stenosis correctly.
