To determine quantitative quality control procedures to evaluate technical variability in multi-center measurements of the diffusion coefficient of water as a prerequisite to use of the biomarker apparent diffusion coefficient (ADC) in multi-center clinical trials.A uniform data acquisition protocol was developed and shared with 18 participating test sites along with a temperature-controlled diffusion phantom delivered to each site. Usable diffusion weighted imaging data of ice water at five b-values were collected on 35 clinical MRI systems from three vendors at two field strengths (1.5 and 3 Tesla [T]) and analyzed at a central processing site.Standard deviation of bore-center ADCs measured across 35 scanners was 10%) vendor-specific and system-specific spatial nonuniformity ADC bias was detected for the off-center measurement that was consistent with gradient nonlinearity.Standardization of DWI protocol has improved reproducibility of ADC measurements and allowed identifying spatial ADC nonuniformity as a source of error in multi-site clinical studies.read more

TL;DR: The purpose of this work was to assess the reproducibility of diffusion imaging, and in particular the apparent diffusion coefficient, intra‐voxel incoherent motion parameters and diffusion tensor imaging parameters, across multiple centres using clinically available protocols with limited harmonization between sequences.

TL;DR: In this article, the authors assessed the repeatability of radiomics features on small prostate tumors using test-retest multiparametric Magnetic Resonance Imaging (mpMRI) and found that the feature's value must remain stable between two scans, if the conditions remain stable.
