Abstract(in English) | MRI, or magnetic resonance imaging, is a medical imaging technique widely used in various healthcare settings. It utilizes the magnetic resonance phenomenon of hydrogen nuclei within the body to obtain cross-sectional images of the body. In this research, we explore the classification problem of tumor types in head MR images using neural networks. Achieving high accuracy in such classifications is anticipated to contribute to automated diagnosis in clinical settings. However, a challenge in MR image classification is the limited availability of real-world data for training. To address this issue, our study employs fine-tuning with existing models to create an accurate model from a restricted dataset. Additionally, since the distribution of tumor occurrence varies based on tumor types, we investigate whether utilizing not only tumor shape but also its positional information can enhance the performance of MR image classification. We evaluate this by conducting experiments using publicly available MR images and their degraded versions. The results confirm that as images degrade, the utility of positional information increases. Notably, providing the positional information as an image proves more effective than presenting it as a 2D coordinate vector for enhancing the usefulness of positional information in the context of tumor classification. |
