Cross-vendor harmonization of T₂ -relaxation-under-spin-tagging (TRUST) MRI for the assessment of cerebral venous oxygenation.

Cerebral venous oxygenation (Yv ) is an important physiological parameter and has potential clinical application in many brain diseases. T2 -relaxation-under-spin-tagging (TRUST) is a commonly used MRI method to measure Yv . Harmonization of this technique across MRI vendors is important for dissemination and multicenter studies of brain oxygenation and metabolism as a disease biomarker.
