Abstract
Objective
To determine the difference in vessel measurements, signal-to-noise ratio (SNR), and
voxel size between contrast-enhanced and noncontrast magnetic resonance techniques
in patients with coarctation of the aorta (CoA).
Materials and methods
In 39 patients, vessel size, SNR, and voxel size were compared in cine magnetic resonance
imaging (MRI), gadolinium-free magnetic resonance angiography (Gd-free MRA), and contrast-enhanced
MRA (ce-MRA).
Results
There was no significant difference in measurement and SNR, but there was a significant
difference in voxel size (P<.001).
Conclusions
Our results show that, in CoA patients, monitoring of vessel size using cine MRI and
Gd-free MRA is equivalent to ce-MRA while being less invasive.
