Motivation: For clinical application uncertainty of DTI and tractography biomarkers is critical to avoid that management decisions are made based on changes that are due to measurement error.
Goal(s): Provide a comprehensive reference guide of estimated uncertainties for DTI and tractography renal biomarkers and use the data to screen these biomarkers based measurement precision.
Approach: Five healthy-volunteers were scanned 4 times on 3T MRI scanner using a diffusion free-breathing protocol. DTI and tractography parameters were calculated using DIPY.
Results: Tractography markers are less precise than DTI, sphericity is the most reliable of all DTI metrics, and histogram metrics kurtosis and skewness are inherently imprecise.
Impact: This study presents comprehensive reference values for error ranges in renal DTI that will help to identify real (patho)physiological changes in future clinical results
