Excerpt
Zhuo et al have compared the 3D and 4D contrast-enhanced magnetic resonance angiography (CE-MRA) from carefully screened seven prior works [
1]. Their summary and conclusions are in favor of 3D CE-MRA and show higher sensitivity from 3D than from 4D datasets that should raise reader concern as well as their interest. The articles that Zhuo et al have analyzed also did not find any significant advantage of high field compared to 1.5 T other than a slightly better time resolution. The MR vendors and clinicians may need to confirm or confront such analysis. Zhuo et al have correctly listed probable causes of such a pattern. In this editorial, plausible explanations with a focus on transmetallation of contrast media (CM) and the susceptibility challenges from high fields in imaging technique development are pointed out. …
