MAG-Net: Multi-task attention guided network for brain tumor segmentation and classification
This work addresses the complex and time-consuming task of brain tumor analysis for radiologists, but it is incremental as it builds on existing deep learning methods for medical imaging.
The paper tackles brain tumor segmentation and classification from MRI images using a multi-task attention guided network (MAG-Net), achieving promising results compared to state-of-the-art models with fewer training parameters.
Brain tumor is the most common and deadliest disease that can be found in all age groups. Generally, MRI modality is adopted for identifying and diagnosing tumors by the radiologists. The correct identification of tumor regions and its type can aid to diagnose tumors with the followup treatment plans. However, for any radiologist analysing such scans is a complex and time-consuming task. Motivated by the deep learning based computer-aided-diagnosis systems, this paper proposes multi-task attention guided encoder-decoder network (MAG-Net) to classify and segment the brain tumor regions using MRI images. The MAG-Net is trained and evaluated on the Figshare dataset that includes coronal, axial, and sagittal views with 3 types of tumors meningioma, glioma, and pituitary tumor. With exhaustive experimental trials the model achieved promising results as compared to existing state-of-the-art models, while having least number of training parameters among other state-of-the-art models.
