This study aims to enhance interpretability and explainability of multi-modal prediction models integrating imaging and tabular patient data.The adapted xAI methods were used to generate explanation maps for identification of relevant image features and error analysis.The dTMs achieve state-of-the-art prediction performance, with area under the curve (AUC) values close to 0.8.Explanation maps calculated from brain imaging dTMs for functional outcome highlighted critical brain regions such as the frontal lobe.
