Answers are grounded in this paper and cite their sources.
Nonenhanced true FISP MR imaging alone is highly accurate for evaluating thoracic aortic dissection and aneurysm, potentially reducing the need for contrast and lengthy imaging protocols.
Comprehensive aortic magnetic resonance (MR) examinations currently include multiple nonenhanced and contrast material-enhanced sequences. The authors hypothesized that the nonenhanced true fast imaging with steady-state precession (FISP) portion alone of their comprehensive imaging protocol would be adequate to confidently confirm or exclude dissection or aneurysm of the aorta. In a retrospective review of 29 comprehensive thoracic aortic MR examinations, nonenhanced true FISP MR imaging alone was 100% accurate for determining the presence or absence of dissection or aneurysm.
