MRI Stroke – Aalborg (DK) Fast Track MRI Stroke Protocol
Aalborg’s fast-track acute stroke MRI protocol is reviewed through diffusion, perfusion, angiographic findings, interpretation pitfalls, and stroke mimics.
Already have an account?
Description
The Aalborg fast-track MRI protocol is reviewed sequence by sequence, including FLAIR, diffusion-weighted imaging and ADC maps, exponential ADC, arterial spin labelling, T2*-weighted imaging, and time-of-flight MR angiography. Practical cases show how to recognise acute infarction and haemorrhage, distinguish seizure-related change and other stroke mimics, and avoid perfusion and flow-related interpretation pitfalls.
Learning Objectives
- Identify the sequences in the Aalborg fast-track stroke MRI protocol and apply a systematic review approach.
- Interpret FLAIR, diffusion-weighted, ADC, exponential ADC, T2*-weighted, and arterial spin-labelling findings in suspected acute stroke.
- Recognise perfusion and time-of-flight angiography pitfalls and distinguish true vessel occlusion from flow-related signal loss.
- Differentiate acute stroke from important mimics, including seizure-related change, herpes simplex encephalitis, transient global amnesia, posterior reversible encephalopathy syndrome, and demyelinating disease.
