Patient
male, 58 year(s)
 
 
  • Figure 1
    Axial diffusion-weighted image

    Multiple watershed infarcts in deep borderzone of left MCA and ACA territory.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR-Diffusion/Perfusion; Procedure: Education; Special Focus: Epidemiology;
     
     
  • Figure 2
    Axial diffusion weighted image

    Small area of acute infarct present in right frontal lobe in same patient.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR-Diffusion/Perfusion; Procedure: Education; Special Focus: Epidemiology;
     
     
  • Figure 3
    TOF MRA axial MIP image

    Bilateral PCAs showing a fetal origin from PComs and P1 segments are absent.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR-Angiography; Procedure: Education; Special Focus: Epidemiology;
     
     
  • Figure 4
    TOF MRA sagittal image, greek letter tau.

    PTA arising from junction between petrous and cavernous ICA running posterolaterally along the trigeminal nerve adjacent to the cavernous sinus making tau sign.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR-Angiography; Procedure: Education; Special Focus: Epidemiology;
     
     
  • Figure 5
    TOF MRA coronal MIP image

    PTA is arising from the right ICA running posterolaterally and then medially to join basilar artery just inferior to the origin of superior cerebellar arteries representing PTA.
