Patient 1. IVIM perfusion fraction color maps (colorbar unitless), showing a lack of brain perfusion, but preserved perfusion of the scalp, which belongs to the perfusion territory of the external carotid artery. The lower row shows the normal IVIM perfusion fraction in a 25-year-old healthy control
