Early detection of atherosclerotic plaques that are prone for rupture can improve preventive strategies in clinical practise. MRI has the promise to identify plaque morphological characteristics that are the hallmark of the vulnerable plaque. Here, we show that high and low spatial resolution measurements change the accuracy and reproducibility of different parameters of the atherosclerotic plaque in a population with carotid atherosclerosis.
