This study aims to assess the diagnostic validity of a new minute-MRI sequence for neuroradiological evaluation in comparison to conventional MRI.
The study aims to assess the imaging quality with regards to artefacts and lesion conspicuity as well as its diagnostic potential in rendering a probable diagnosis. The primary study aim is to define the AUC for diagnostic performance of minute MRI compared to conventional MRI.
Included patients are those with suspiscion of cerebral pathology.
Study participancts are investigated at 3T.
