There is an increasing interest in magnetic susceptibility or T2* MR imaging to replace or complement DCE-MRI for vascular assessment of therapeutic interventions in early treatment response monitoring, as this circumvents the need for a contrast agent. In this study we focused on the reproducibility of T2* MR imaging in patients with liver metastases of colorectal cancer. Histogram analysis were performed and reproducibility was assessed for the mean T2*, the 16th and 84th percentile values. On average T2* showed good mean and histogram reproducibility. A trend towards a negative correlation with mean ADC values was observed.
