Motivation: Proton therapy is a relatively new option for treatment of uveal melanomas. For adequate treatment, accurate measurement of tumour dimensions and tumour-marker distance is essential. The dedicated MRI protocol for uveal melanoma patients developed in our institution could be helpful.
Goal(s): In this study, we compared MRI-based measurements with conventional ophthalmic measurements.
Approach: Retrospectively, MRI based measurements of tumour dimensions and marker-tumour distances in 23 patients were compared with conventional ophthalmic measurements and evaluated.
Results: MRI allowed for the three-dimensional assessment of the tumour. In specific patients, it provided a more reliable measurement of tumour dimensions and marker-tumour distances.
Impact: Dedicated ocular MRI proved to be a reliable tool for measurements required in the planning of proton therapy in patients with uveal melanoma.
