Magnetic resonance angiography (MRA) has evolved over the past years from an experimental imaging modality to a technique that is now widely applied in clinical practice. This article reviews the fundamentals of the different magnetic resonance angiographic techniques and how they can be applied for abdominal and peripheral arterial imaging. Currently, contrast-enhanced magnetic resonance angiography (CE-MRA), whereby a luminogram is obtained during initial arterial passage of contrast material… Expand
Management of peripheral arterial disease: role of computed tomography angiography and magnetic resonance angiography.
TLDR
The technical requirements to perform adequate CTA and MRA examination, the relative indications of both modalities for the diagnosis and management of peripheral arterial occlusive disease (PAOD), abdominal and peripheral aneurysm diseases and the main imaging features observed in patients will be detailed. Expand
MRA: Current Applications in Body Vascular Imaging
TLDR
Current uses of CTA are many, including perioperative imaging and planning of endovascular aneurysm repairs (EVAR) and imaging of the abdominal aorta and visceral vessels and MRA is gaining popularity as applications increase image quality and decrease acquisition time. Expand
Peripheral MR angiography.
TLDR
Various techniques of peripheral MR angiography are discussed, including step-by-step, hybrid, continuous table movement, and non-contrast-enhanced MRAngiography. Expand
Initial experience with imaging of the lower extremity arteries in an open 1.0 Tesla MRI system using the triggered angiography non-contrast-enhanced sequence (TRANCE) compared to digital subtraction angiography (DSA)
TLDR
Non-contrast-enhanced imaging of the lower limb arteries using a TRANCE-sequence in a 1.0 T open MRI system is feasible with the protocol presented; however, TRANCE tends to underestimate larger vessels and overestimate smaller vessels compared to DSA. Expand
Recent advances in magnetic resonance imaging for peripheral artery disease
TLDR
Novel MRI techniques such as arterial spin labeling, blood-oxygen-level dependent imaging (BOLD), and first-pass perfusion gadolinium enhancement are advancing the field by providing skeletal muscle perfusion/oxygenation data while maintaining excellent spatial and temporal resolution. Expand
Quiescent-Interval Single-Shot Magnetic Resonance Angiography
TLDR
The various NEMRA protocols are discussed, followed by a comprehensive review of the literature on QISS MRA to date, with a particular emphasis on Qiss MRA feasibility studies and studies comparing the diagnostic accuracy and image quality of Q ISS MRA versus other diagnostic imaging techniques in PAD. Expand
Advances in diagnostic imaging for peripheral arterial disease
TLDR
The advantages, disadvantages and recent advances in the commonly used clinical applications of duplex ultrasonography, magnetic resonance angiography, computed tomographic angiographers, digital subtraction angiographies and intravascular ultrasound for arterial imaging in the lower extremities are reviewed. Expand
Theory, Technique, and Practice of Magnetic Resonance Angiography
TLDR
A window is provided into how magnetic resonance images are generated, which techniques may be employed, and the potential advantages and limitations of various techniques and to discuss the future role MRA may have for the vascular physician. Expand
Diagnostic performance of gadobenate dimeglumine enhanced MR angiography of the iliofemoral and calf arteries: a large-scale multicenter trial.
TLDR
Improved diagnostic performance and reproducibility are achievable with gadobenate dimeglumine-enhanced MR angiography in patients with peripheral arterial occlusive disease. Expand
High-resolution MRI in giant cell arteritis: imaging of the wall of the superficial temporal artery.
TLDR
Initial results with this noninvasive MRI of the temporal artery agreed well with histologic results and with the clinical criteria of the American College of Rheumatology. Expand
