Identifying perfusion deficits on CT perfusion images using temporal similarity perfusion (TSP) mapping

ConclusionsTSP maps are easier to interpret for inexperienced readers. Perfusion deficits detected by TSP are smaller which may suggest less dependence on transit delays although more investigation is required.Key Points• Temporal similarity perfusion mapping assesses CTP data based on similarities in signal time-curves.• TSP maps are comparable in perfusion deficit detection to deconvolution maps.• TSP maps are easier to interpret for inexperienced readers.
