Abstract:
An increasing number of patients with an acute stroke syndrome are being admitted to hospitals with on-site echoplanar MRI scanners. In this pictorial review, we describe our experience of an MRI protocol in the first 150 such patients scanned in our hospital. We illustrate some of the advantages of using echoplanar MRI. Diffusion and susceptibility weighted acquisitions may supplement conventional MR sequences by providing useful additional information about the age and location of the lesion, together with a high sensitivity to the presence of blood breakdown products.
Insights
Echoplanar MRI (Magnetic Resonance Imaging) aids in diagnosing acute stroke by providing crucial details on lesion age and location. This advanced imaging technique offers high sensitivity for detecting blood breakdown products, improving stroke assessment.
Area of Science:
- Radiology
- Neurology
- Medical Imaging
Background:
- Growing number of acute stroke patients admitted to hospitals with on-site echoplanar MRI scanners.
- Need for efficient and informative imaging protocols for acute stroke assessment.
Purpose of the Study:
- To describe the experience and utility of an MRI protocol for acute stroke patients using echoplanar MRI.
- To illustrate the advantages of echoplanar MRI in stroke diagnosis.
Main Methods:
- Review of MRI scans from the first 150 acute stroke patients scanned with an on-site echoplanar MRI scanner.
- Utilized diffusion and susceptibility weighted imaging sequences as part of the MRI protocol.
Main Results:
- Echoplanar MRI provides valuable additional information complementing conventional MR sequences.
- Diffusion and susceptibility weighted imaging demonstrate high sensitivity for detecting blood breakdown products.
- These sequences aid in determining the age and location of ischemic or hemorrhagic lesions.
Conclusions:
- Echoplanar MRI is a valuable tool for the rapid assessment of acute stroke syndromes.
- The described MRI protocol effectively utilizes advanced sequences to enhance diagnostic accuracy.
- This imaging approach offers significant advantages in identifying key features of stroke pathology.
