Key result
MRI enables comprehensive, reproducible evaluation of the thoracic aorta via high-resolution imaging and flow analysis.
Why the study?
Recent advances in MR imaging techniques are positioning MR as a leading modality for comprehensive evaluation of thoracic aortic disease, challenging the traditional reliance on CT.
Recent advances in MR imaging provide a comprehensive and reproducible modality for evaluating thoracic aortic pathology through high-resolution morphological imaging and vascular flow analysis.
May aid detailed thoracic aortic assessment where available; leaves open optimal modality selection versus CT in routine practice.
A number of congenital defects and acquired disease processes affect the thoracic aorta, and traditionally, computed tomography (CT) has been the mainstay of imaging, especially in evaluation of the acute aorta. However, recent advances in magnetic resonance (MR) imaging such as electrocardiographically (ECG) triggered breath-hold sequences and ultrafast 3-dimensional MR angiography (MRA) are bringing MR imaging to the forefront of imaging of the thoracic aorta. By providing high-resolution morphological imaging and sophisticated vascular flow analysis for functional data, this modality can provide a comprehensive, reproducible evaluation of the thoracic aorta. In this review, we discuss the role of MR imaging in the evaluation of thoracic aorta pathology along with pertinent examples of aortic abnormalities.

Lichtenberger et al. (2018) conducted a review in Thoracic aortic disease. Magnetic resonance (MR) imaging vs. Computed tomography (CT) was evaluated. Magnetic resonance imaging provides high-resolution morphological imaging and sophisticated vascular flow analysis for a comprehensive, reproducible evaluation of the thoracic aorta.
