We investigate the diagnostic applicability and
performance of three-dimensional stereotactic surface
projections (3D-SSP), a commonly used tool for molecular
brain PET imaging, as applied to arterial spin labeling
in clinical MR examinations. Expert reader assessment
found that the 3D-SSP method was generally preferred
over the traditional method of ASL display. We conclude
that 3D-SSP statistical mapping is feasible in a
clinical population and enables quantitative data
extraction and reliable localization of perfusion
abnormalities by means of stereotactic coordinates in a
condensed display. This technique may provide added
value in the clinical assessment of a variety of
neurological pathologies.
