Peripheral contrast-enhanced MR angiography is widely used for anatomical imaging of the arterial system of the lower limb. There are several pitfalls in the planning, acquisition, and interpretation of these studies that can result in the loss of important diagnostic information, as well as artefacts that can be misinterpreted as disease entities. This review illustrates the range of these potential sources of error and how to avoid them.
