Deep learning methods, specifically 3D convolutional neural networks (CNNs), have been used to classify these anomalies. However, CNNs have limitations in capturing long-range dependencies across the low and high level features, potentially reducing performance. To address this, we propose an end-to-end pipeline using a novel deep learning network called ConTra-Net. ConTra-Net combines the strengths of CNNs and self-attention mechanisms of transformers to classify paranasal anomalies in the maxillary sinuses. Our approach outperforms 3D CNNs and 3D Vision Transformer (ViT), with relative improvements in F1 score of 11.68% and 53.5%, respectively. Our pipeline with ConTra-Net could serve as an alternative to reduce misdiagnosis rates in classifying paranasal anomalies.en1605-74222024SPIEanomaly classificationCNNHybrid Networkmaxillary sinusParanasal anomalyTransformerMLE@TUHHComputer Science, Information and General Works::004: Computer SciencesTechnology::610: Medicine, HealthTechnology::620: EngineeringConference Paper10.1117/12.3005515Conference Paper
