Recent advances in ocular MRI
make it possible to acquire high resolution three dimensional images of uveal
melanoma in eye tumour patients, allowing a much better assessment of the
maximal tumour prominence compared to conventional clinical ultrasound
measurements. Nine uveal melanoma
patients were examined on a 7 Tesla using a custom-built eye-coil. Eye-motion
artefacts were minimized by the use of a cued-blinking protocol. For all
patients the MR-images showed a slightly lower tumour prominence. For two of
these patients this resulted in a substantial change in treatment planning,
saving an eye that would otherwise have been removed.
