Do I need contrast medium?
Contrast agents are used to improve the representation of structures. The MRI images are black and white, and since there are not infinite shades of grey, it is sometimes difficult to distinguish between different tissues. For the diagnosis of stroke, the diffusion MRI is particularly important.
Diffusion MRI shows areas in which diffusion (mass transport) is restricted and the cells are thus irreversibly damaged. No contrast agents are required for this examination. The radiologist decides in each individual case whether contrast medium is given or not. is dangerous.
When do you do a follow-up?
A follow-up based on imaging is rather unusual. Regular follow-up care after a stroke begins with inpatient or outpatient rehabilitation, depending on the severity of the stroke. The aim is to restore functions such as speech and motor functions through physiotherapy, speech therapy and occupational therapy. The patient trains to master the (professional) everyday life again independently.
Does an MRI help to better assess the risk of stroke?
MRI is not performed prophylactically to determine the risk of stroke. It is only used in cases of justified clinical suspicion. It is more effective to minimize the known risk factors. These include: can.
- Restriction of smoking
- Adjusting the blood pressure
- Treatment of cardiac arrhythmias
- Change of diet
- Reduction of overweight
- Light athletic activity
- Stress avoidance
