MR Angiography for Aortic Diseases.

Area of Science:

• Cardiovascular Imaging
• Radiology
• Vascular Medicine

Background:

• Aortic pathologic conditions encompass a range of disorders, including aortic aneurysm, acute aortic syndrome, traumatic aortic injury, and atherosclerosis.
• Nonspecific clinical presentations necessitate reliable noninvasive imaging for effective patient management.

Purpose of the Study:

• To review the role of noninvasive imaging modalities in the screening, diagnosis, management, and surveillance of aortic pathologic conditions.
• To highlight the current landscape and future directions for advanced magnetic resonance (MR) imaging applications in aortic disease.

Main Methods:

• Review of commonly used noninvasive imaging modalities: ultrasound, computed tomography (CT), and MR imaging.
• Discussion of factors influencing the choice of imaging modality, including clinical presentation, suspected diagnosis, and institutional practices.
• Exploration of advanced MR techniques, such as four-dimensional flow (4D flow) MR imaging.

Main Results:

• Ultrasound, CT, and MR imaging are essential for managing aortic conditions.
• The selection of imaging modality is guided by clinical acuity, diagnostic suspicion, and available resources.
• Advanced MR applications require further investigation to establish their clinical utility and define usage guidelines.

Conclusions:

• Noninvasive imaging plays a critical role in the comprehensive management of diverse aortic pathologic conditions.
• Current imaging choices are multifactorial, balancing clinical needs with practical considerations.
• Further research into advanced MR techniques, like 4D flow, is essential to optimize patient care for aortic diseases.
