Staging of retinoblastoma – the most common
pediatric eye cancer – is currently performed in vivo at 1.5 or 3.0 T and
allows for images with voxel sizes <0.5x0.5x2 mm3. We performed ex
vivo ultrahigh-resolution MRI at 9.4 and 17.6 T of enucleated retinoblastoma
eyes. This method allowed us to generate high-resolution images (voxel size:
59x59x59 to 100x100x100 μm3) of different aspects of retinoblastoma
showing the potential of ultrahigh-resolution MRI for staging retinoblastoma
and gaining insight in anatomical details.
