文摘
- •
CT perfusion (CTp) is a promising technique to assess anti-angiogenic therapies.
- •
Patient motion and CTp artefacts prevent reliable quantitative measurements.
- •
Tumour heterogeneity makes quantifying reliability of results very challenging.
- •
The local-based index we propose discriminates between heterogeneity and noise.
- •
The index helps comparing perfusion maps and improving reliability of CTp studies.
