ECG-gated CTA is the clinical standard for non-invasive
assessment of the thoracic aorta, but exposes patients
to ionizing radiation and nephrotoxic contrast. An ECG-gated
3D breath hold non-enhanced balanced steady state free
precession (bSSFP) MRA technique (NE MRA) has recently
been described that offers a contrast and radiation-free
alternative, particularly applicable to long-term
surveillance of younger patients. We evaluate its
performance in a clinical population, with eCTA as the
reference standard. In our preliminary experience, NE
MRA identifies aortic pathology with satisfactory
diagnostic confidence and image quality, inferior to
eCTA. Measured aortic dimensions in the proximal
thoracic aorta are comparable.
