In this study we have investigated neuronal changes in a longitudinal study using anatomical and structural MRI before and after pansinus surgery. Neuronal changes measured by means of DTI before and after surgery were compared to changes in olfactory performance. The analysis was carried out using a tract specific analysis involving probabilistic tractography and subsequent alignment of control points along the cingulum bundles. Patients, which showed an improvement >10 in olfactory performance measure, showed also a significant increase in radial diffusivity in the middle segment of the left cingulum bundle.
