Deep Neural Networks to the Detection of Lumbar Hernias: Methodology and Preliminary Results
摘要
The growing demand for lumbar spine MRI exams, coupled with a shortage of radiologists, highlights the need for automated diagnostic tools for spinal conditions. Despite advancements in AI across radiology, no CE or FDA-approved solutions currently target lumbar spine pathologies. This paper introduces a deep learning pipeline designed to automatically detect intervertebral disc herniation, aiming to support faster and more accurate clinical decisions. A dataset of 165 lumbar spine MRI exams, totalling 5,200 sagittal slices from four manufacturers, was annotated by radiologists. The experiment includes a multi-stage approach. MA-Net with EfficientNet-B2 achieved the best segmentation results, reaching a Dice Score of 0.898. For herniation classification, the ViT model outperformed others, achieving an F1-Score of 0.905 and accuracy of 0.826. Simplifying the segmentation task to three classes enhanced robustness, and anatomical labelling enabled precise disc-level classification. The pipeline demonstrates the feasibility of automated herniation detection in lumbar MRI, supporting improved diagnostic consistency and reduced radiologist burden.
