BIRADS classification is one of the standard of reporting breast MRI. It reveals the information about the likelihood of cancer and management recommendation for the patients. In this study, we aimed to develop and evaluate a 3D convolution neural network (CNN) for breast MRI BIRADS classification. This 3D CNN network was evaluated and it achieved overall 90% classification accuracy. In particular, the network also has high sensitivity (100%) of highly suspicious of malignancy findings. The results suggested that a deep learning-based computerized tool might be useful in BIRADS-MRI classification.
