Aim: Assessment of all brain MRIs in our hospital done during one-year period and finding out the frequency of each diagnosis with the image of diffusion restriction.

Methods: We found 324 examinations, that shown diffusion restriction out of 6.001 brain MRIs. In those we assessed size, localisation and in ischemia the time passed from the onset of a stroke and correlation of changes on FLAIR.

Results: Acute ischemia was diagnosed in 189 patients (58%), haemorrhage (mostly postoperative) in 68 (21%), tumour in 50 (15%) and other etiology in 17 patients (5%). Patients with acute ischemia and tumours were significantly older than patients in remaining groups.

Conclusion: In everyday practise we encounter diffusion restriction in acute ischemia, but there are more diagnoses with these finding, and it is good to know them (list of them is in the discussion of this article). MR should be always described with the knowledge of patients' clinical status and findings on remaining MRI sequences.
