An Open, Reproducible Gamma-Variate Pipeline for CT-Perfusion Time–Attenuation Curve Analysis, with Standardized (ASIST-Japan) Map Visualization

2026-06-29

Abstract excerpt

CT perfusion (CTP) is central to acute-stroke and oncologic imaging, yet quantitative outputs vary substantially across vendor software, undermining reproducibility. We present an open, transparent core (ctp-core) that fits first-pass time–attenuation curves with a gamma-variate model, derives perfusion indices (peak enhancement, time-to-peak [TTP], bolus-arrival time [BAT], area under the curve [AUC]) analyticall...
