ROC evaluation of statistical wavelet-based analysis of brain activation in [15O]-H2O PET scans
This paper presents and evaluates a wavelet-based statistical analysis of PET images for
the detection of brain activation areas. Brain regions showing significant activations were
obtained by performing Student's t tests in the wavelet domain, reconstructing the final
image from only those wavelet coefficients that passed the statistical test at a given
significance level, and discarding artifacts introduced during the reconstruction process.
Using Receiver Operating Characteristic (ROC) curves, we have compared this statistical …
