Summary
Magnetic resonance angiography (MRA) offers new clinical applications in vascular imaging. This technique is reducing the need for conventional angiography and ultrasound procedures.
Area of Science:
- Medical Imaging
- Radiology
- Cardiovascular Imaging
Background:
- Magnetic resonance imaging (MRI) technology is rapidly advancing.
- Magnetic resonance angiography (MRA) is a key development in vascular imaging.
- Conventional angiography and duplex Doppler ultrasound have been standard diagnostic tools.
Purpose of the Study:
- To describe the clinical applications of magnetic resonance angiography.
- To provide an introduction to new magnetic resonance imaging techniques for readers unfamiliar with the field.
- To highlight the growing clinical utility of MRA.
Main Methods:
- Literature review of vascular and flow MRI from Index Medicus (1988-1991).
- Inclusion of contributions from the 19th Annual Meeting of the American Society of Neuroradiology (1991).
- Inclusion of contributions from the 10th Annual Conference of the Society of Magnetic Resonance in Medicine (1991).
Main Results:
- Magnetic resonance angiography is finding numerous clinical applications.
- MRA is demonstrating efficacy in diagnosing vascular conditions.
- The use of MRA is associated with a reduction in conventional angiography procedures.
Conclusions:
- Magnetic resonance angiography is a valuable and evolving clinical tool.
- MRA offers a promising alternative to established vascular imaging modalities.
- Continued advancements in MRI are expanding the clinical utility of MRA.
