QASL is our vendor-agnostic post-processing solution that is compatible with any variant of ASL. It provides the following advanced features
QI’s ASL solution
Automated QC
Automated QC spots many of the common acquisition issues that are unique to ASL, accelerating trials workflows and improving the quality of statistical analyses.
Data normalisation
Data normalisation reduces inter-subject variability due to natural and technical factors.
QI’s normalisation strategies increases the detectability of disease-induced perfusion effects compared to Z-transforms.
Image deblurring
3D acquisitions increase the SNR of ASL but introduce substantial blurring in the Z-axis, increasing the PSF of acquisition.
QI’s deblurring technology corrects this artefact, leading to more accurate regional measures.
Synthetic healthy controls
QI’s normative population modelling can predict healthy baseline CBF based on age, sex and anatomy. This can be used to improve the matching of control groups in a study.
Surface analysis
Surface analysis is a powerful tool for group analysis of BOLD fMRI data. QI has developed the world’s first dedicated pipeline for surface-based ASL.
Regional biomarker measurement
QASL seamlessly integrates structural MRI to automatically report summary perfusion statistics within segmented ROIs.
