Venous mapping is important in end stage renal disease patients requiring vascular access for hemodialysis. We compare image quality (IQ) and measured vessel caliber of FSE based non-contrast MRV (NC-MRV) to contrast-enhanced MRV (CE-MRV) and US in available segments in 10 healthy volunteers. Central and arm vein IQ was diagnostic, but forearm vein IQ was suboptimal, inferior to CE-MRV. No difference in vessel caliber between sequences was demonstrated for most segments between NC-MRV and CE-MRV, but both MRV techniques yielded significantly larger caliber measurements than US, raising concern regarding application of MRV-derived measurements to clinical practice.
