  • Figure 1
    Unenhanced CT

    Unenhanced CT shows hyperdense vessel sign in right middle cerebral artery.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Embolism / Thrombosis;
     
     
  • Figure 2
    Angiography CT

    Angio-CT shows thrombi in right middle cerebral artery and occlusion of right internal carotid.

     
    Area of Interest: Head and neck; Imaging Technique: CT-Angiography; Procedure: Diagnostic procedure; Special Focus: Ischaemia / Infarction;
     
     
  • Figure 3
    CT perfusion

    A larger ischaemic than infarcted area was shown by CTP using the time to peak images and the mean transit time (MTT) and relating them to the cerebral blood volume (CBV) images.

     
    Area of Interest: Head and neck; Imaging Technique: CT-Quantitative; Procedure: Treatment effects; Special Focus: Ischaemia / Infarction;
     
     
  • Figure 4
    DWI MR and CT perfusion

    MR shows diffusion restriction in infarcted area as the map of cerebral blood volume on the perfusion CT.

     
    Area of Interest: Interventional vascular; Imaging Technique: MR; Procedure: Treatment effects; Special Focus: Ischaemia / Infarction;
     
     
  • Figure 5
    Angiographic imaging

    Angiographic image shows occlusion of middle cerebral artery.

     
    Area of Interest: Vascular; Imaging Technique: Catheter arteriography; Procedure: Thrombolysis; Special Focus: Ischaemia / Infarction;
     
     
  • Figure 6
    Angiographic imaging

    Angiogrpahic controls after the use of thrombus aspiration system (Penumbra).

     
    Area of Interest: Vascular; Imaging Technique: Catheter arteriography; Procedure: Thrombolysis; Special Focus: Ischaemia / Infarction;
     
     
  • Figure 7
    MR

    MR and angio-MR after endovascular thrombolysis.
