Abstract:
Noninvasive diagnostic procedures as spiral-CT (CT-angiography and perfusion-CT) as well as MRI-techniques (diffusion-imaging, perfusion-imaging and MR-angiography) have enriched the diagnostic modalities in acute stroke. Angiography by MRI or CT has replaced digital subtraction angiography in most acute stroke cases. Despite of the advantages of MRI, CT still remains the procedure of choice in acute stroke. 1. Acute hematoma is easily detected by CT. 2. Occlusion of the main arterial stems are identified by CT-angiography. CT fulfills all the requirements for therapeutic decisions in acute stroke.
