Abstract The early and accurate diagnosis of brain tumors is critical for effective treatment planning, with Magnetic Resonance Imaging (MRI) serving as a key tool in the non-invasive examination such conditions. Despite advancements Computer-Aided Diagnosis (CADx) systems powered by deep learning, challenge accurately classifying from MRI scans persists due to high variability tumor appearances subtlety early-stage manifestations. This work introduces novel adaptation EfficientNetv2 architecture, enhanced Global Attention Mechanism (GAM) Efficient Channel (ECA), aimed at overcoming these hurdles. enhancement not only amplifies model’s ability focus on salient features within complex images but also significantly improves classification accuracy tumors. Our approach distinguishes itself meticulously integrating attention mechanisms that systematically enhance feature extraction, thereby achieving superior performance detecting broad spectrum Demonstrated through extensive experiments large public dataset, our model achieves an exceptional high-test 99.76%, setting new benchmark MRI-based classification. Moreover, incorporation Grad-CAM visualization techniques sheds light decision-making process, offering transparent interpretable insights are invaluable clinical assessment. By addressing limitations inherent previous models, this study advances field medical imaging analysis highlights pivotal role enhancing interpretability learning models diagnosis. research sets stage advanced CADx systems, patient care outcomes.

In the diagnosis and treatment of brain tumors, automatic classification segmentation medical images play a pivotal role. Early detection facilitates timely intervention, significantly improving patient survival rates. This study introduces novel method for automated aiming to enhance both diagnostic accuracy efficiency. Magnetic Resonance (MR) imaging remains gold standard in clinical tumor diagnostics; however, it is time-intensive labor-intensive process. Consequently, integration detection, localization, methods not only desirable but essential. this research, we present framework that enables post-classification feature extraction, allowing first-time multiple types. To improve characterization, applied data augmentation techniques MR developed hierarchical multiscale deformable attention module (MS-DAM). model effectively captures irregular complex patterns, enhancing performance. Following classification, comprehensive process was conducted across large dataset, reinforcing model's role as decision support system. Utilizing Kaggle dataset containing 14 different types with highly similar morphologic structures, validated proposed efficacy. Compared existing multi-scale channel modules, MS-DAM achieved superior accuracy, exceeding 96.5%. presents promising approach tumors imaging, offering significant advancements clinics paving way more efficient, accurate, scalable methodologies.

Learning multi-scale feature representations is essential for medical image segmentation. Most existing frameworks are based on U-shape architecture in which the high-resolution representation recovered progressively by connecting different levels of decoder with low-resolution from encoder. However, intrinsic defects complementary fusion inhibit aggregating efficient global and discriminative features along object boundaries. While Transformer can help model features, their computation complexity limits application real-time scenarios. To address these issues, we propose a Cross-scale Fusion Network (CFNet), combining cross-scale attention module pyramidal to fuse multi-stage/global context information. Specifically, first utilize large kernel convolution design basic building block capable extracting local Then, Bidirectional Atrous Spatial Pyramid Pooling (BiASPP), employs atrous bidirectional paths capture various shapes sizes brain tumors. Furthermore, introduce cross-stage mechanism reduce redundant information when merging two stages semantics. Extensive evaluation was performed five segmentation datasets: 3D volumetric dataset, namely Brats benchmarks.

The proposed research focuses on how an early and reliable brain tumor diagnosis by MRI can help the patient through timely intervention, which is of utmost importance. Currently, radiologists conduct a manual interpretation images, lengthy process usually accompanied failure to detect small complex tumors in large dataset. To improve detection, this work applies deep learning models with CNN based neural network for more accurate diagnosis. Sufficient preprocessing techniques are utilized reduce noise enhance contrast within region where spots located but without important details being ignored. Future efforts involve modifying structure investigating possibility transfer better performance different datasets. This aims quality automated medical imaging systems would have overturned effect outcomes while assisting development faster, reliable, precise diagnostic tools.
