Diffuse large B-cell lymphoma (DLBCL) is a common and aggressive subtype of non-Hodgkin lymphoma. This study aimed to evaluate the effectiveness of deep learning for automatically segmenting DLBCL lesions in positron emission tomography (PET) images, which is crucial for treatment planning and monitoring. A 2D U-Net convolutional neural network was trained on a dataset of FDG-PET scans from 150 DLBCL patients. The model's performance was evaluated using two key metrics: the Dice similarity coefficient (DSC) and the Jaccard index. The results showed a mean DSC of 0.71 and a mean Jaccard index of 0.62, indicating accurate identification of lymphoma lesions. These findings suggest that deep learning-based automated segmentation holds great potential for accurately detecting and delineating DLBCL lesions, thereby improving the precision and effectiveness of treatment planning and monitoring for affected individuals.
