Description
Over the last 20 years, diagnostic cross-sectional imaging of arterial diseases has become less and less invasive, with the advent of MR angiography (MRA) and CT angiography (CTA). However, with the increasing proportion of elderly patients, some precautions are needed to avoid the two main complications of these techniques: development of nephrogenic systemic fibrosis with the former, and aggravation of a preexisting renal insufficiency with the latter. Moreover, CT angiography is inevitably associated with a high radiation dose that is problematic when younger patients need to be examined and monitored for various artery diseases (for example, patients with Marfan disease, Takayasu arteritis…). All the manufacturers have attempted during the 3 last years to find solutions in order to decrease potential hazards due to contrast medium administration with either CT or MR, and to reduce radiation dose with CT. Several scientific studies ensued or are under consideration for clinical validation.
