Figure 6From: Beyond blood brain barrier breakdown – in vivodetection of occult neuroinflammatory foci by magnetic nanoparticles in high field MRIVSOP contrast in different MR sequences. Prominent contrast-enhancing periventricular lesions are depicted 24 h after VSOP injection on coregistered coronal T2*-, T2-, T1- and proton-density-weighted images (ellipse). T2*-weighted MRI was most sensitive in detecting magnetic nanoparticles. On T1-weighted images, very high VSOP concentrations became visible as hypointense spots at 7 Tesla.Back to article page
