Brain Health
Brain health over time
A single scan records a moment. Longitudinal imaging asks whether observations at different moments can be compared on the same terms.
An individual baseline
An earlier scan can provide a point of reference. The interval between scans, how they were acquired and the question being asked all shape what a comparison might mean.
Interpreting a difference
If a measurement changes, how much variation would be expected from repeating the scan or the analysis? This question must be addressed before an apparent trend can be interpreted.
The wider picture
A future study could examine how imaging measures relate to other observations over time. This is a scientific direction for Hengora. Personal scan interpretation and clinical care are outside our current activities.
