Figure2: Salivary production in each mouse versus probability of a mouse being classified as a control mouse. Line represents a linear regression. Pearson’s correlation coefficient r is given.

Conclusion: Attention-based classifiers with standard MRI have the potential for classification and early identification of individuals at risk of developing toxicity.

Keywords: Early detection, H&N toxicity, Vision Transformer
