The aim of this study was to identify the contribution of various factors that may have an impact on accuracy of measurements of apparent diffusion coefficients (ADC) in breast MRI. We have considered the effect of long-term scanner stability, positional dependence within the coil, scan-scan repeatability and the effect of single and multiple observers on final measurements of whole tumour and lowest ADC values within tumours. We conclude that scan-scan repeatability and scanner stability have minimal effect on measured ADC values and the biggest influence on measured ADC values is inter-observer repeatability.
