AI Article Synopsis
- The study aimed to compare vessel measurements, signal-to-noise ratios (SNR), and voxel sizes in patients with coarctation of the aorta using different MRI techniques.
- In a sample of 39 patients, the researchers found no significant differences in vessel size or SNR, but identified a significant difference in voxel size.
- The conclusion suggests that cine MRI and gadolinium-free MRA can effectively monitor vessel size in CoA patients and are less invasive than contrast-enhanced MRA.
Article 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.
