Medical image fusion: a proposed methodology for treatment evaluation

Medical image fusion allows to combine multiple images from single or multiple imaging modalities to improve the imaging quality. It supports physicians in performing more accurate clinical decisions and analysis based on medical images. Hybrid imaging with FDG PET/CT is became a standard in the day-to-day clinical practice for management of cancer because it combines the subtle biologic changes detected by FDG PET with the anatomic information offered by CT scans.In this context, we consider hybrid imaging with FDG PET/CT to propose a methodology aiming to use the fusion CT and PET images to evaluate drug administration in patients undergoing treatment.
