AB  - 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.
