Objective: The purpose of this study was to assess the utility of assessment of tumor size and enhancement with diffusion-weighted and conventional MRI in the evaluation of response to transarterial chemoembolization therapy for metastatic ocular melanoma.
Conclusion: In patients with ocular melanoma and liver metastasis treated with transarterial chemoembolization, functional MRI showed significant changes in the lesions. These changes included a decrease in tumor enhancement and an increase in the apparent diffusion coefficient of the tumor, suggesting increasing tumor necrosis and cell death.
