| Abstract | This paper describes research exploring the problems associated with interpreting regional blood flow measurements in the brain. We investigate a method for separating normals from those with cerebral diseases, where the disease is caused by, or has resulted in, altered cerebral haemodynamics. Cerebral perfusion maps are divided into 10 vascular territories. The variance scaled mean values from each region are used to determine 10 principle axes of the normal data. We demonstrate that normal variability in these axes is large, but that our technique is capable of detecting measurable perturbations in cerebral haemodynamics. It is also possible to localise disease groups with known vascular change within a portion of the normal space. |
