This dataset contains anonymized axial magnetic resonance imaging (MRI) data of abdominal region of eighteen in vivo participants having an abdominal hernia, in both axial and sagittal planes. The acquisitions were made both before and after their hernia surgery, performing three exercises: breathing, coughing and Valsalva.

This dataset includes anatomical MRI slices and corresponding segmented masks, providing insights into muscle activity and anatomical structures under different exercise conditions.
