Brain Tumor Diagnosis with Computer Vision

Doctors traditionally rely on MRI scans for diagnosing conditions like cancer, but these images alone are sometimes insufficient, as seen in glioblastoma cases where tissue extraction is necessary. A computer-aided solution, using deep learning, can enhance diagnostic accuracy and speed. The article demonstrates building a classifier to predict tumor presence from MRI scans, utilizing data from a Kaggle competition. The dataset includes DICOM files, a standard for medical images, which are processed using Python's PyDicom package. Understanding metadata such as image size, color channels, and pixel spacing is crucial for processing these images. The classifier employs a 3D convolutional neural network (CNN) built with the MONAI framework, trained on a 3D representation of brain images constructed from 2D slices. Although the model reached the top of the competition leaderboard, its performance suggests that additional data could improve results. Despite technological advancements, the article emphasizes that deep learning models should complement, not replace, medical professionals due to their lack of interpretability.
