The goal of this clinical trial is to evaluate the performance characteristics of O-(2-[18F]fluoroethyl)-L-tyrosine (FET) PET in differentiating pseudoprogression from tumour progression in patients with equivocal conventional imaging and determine the sensitivity and specificity of [18F]FET-PET in delineating disease. The main question[s] it aims to answer are:

| FET PET | Experimental | Upon recruitment, a single study visit will be scheduled where subjects undergo a limited 18F-FET PET/CT of the brain in SGH. After the study visit, from time of recruitment, they will continue their regular clinic visits as clinically indicated, where they will be monitored for at least a year for stability or deterioration. If clinically indicated, they may undergo conventional MRI, alternative MRI imaging and/or histopathological correlation in their respective primary institutions. During these follow-up visits, any adverse effects possibly attributed to the 18F-FET PET/CT can also be flagged up. Any alternative MRI imaging performed (as part of clinical practice in the respective primary institutions) within 4 weeks of the 18F-FET PET/CT study will also be included in the comparative analysis. |

| FET PET | Diagnostic Test | There is only one study visit during which study subjects will undergo a 18F-FET PET/CT in SGH. Following that, they will be followed up as per their routine clinical care. Data collection timepoints will be at 30 days, 4 months, 8 months and 1 year. |
