Since its introduction in 1993,1 contrast-enhanced magnetic resonance angiography (ce-MRA) has been considered the technique of choice for angiographic examination of most regions of the body. This is because of several technical and clinical advantages in comparison with non-contrast-enhanced MRA (nce-MRA) imaging. In this article, we focus on patients with suspected peripheral arterial…

Systemic atherosclerosis involves all major arterial vessels, including the carotid and intracranial arteries, coronary circulation, thoracic and abdominal aorta, internal iliac arteries, renal arteries and peripheral vasculature. This generalised disease contributes to cardiac ischaemic disease, stroke, limb loss and a range of other illnesses, and is the major cause of morbidity and mortality…

There are many things in life everybody wants more of, and this is particularly true for magnetic resonance imaging (MRI). The major challenge in the daily life of an MRI professional is gaining maximal image signal and contrast in a reasonable amount of time. The application of gadolinium (Gd)-based MR contrast material has offered contrast features in MRI that have been used and appreciated for…

Atherosclerosis is a generalised disease and contributes to cardiac death, stroke, limb loss and a range of other illnesses. Disease in the major arteries, including the infra-renal abdominal aorta, internal iliac arteries, renal arteries and peripheral vasculature, remains a major cause of morbidity and mortality. For example, the prevalence of disease in the infra-renal abdominal aorta ranges…

Contrast-enhanced magnetic resonance angiography (ce-MRA) has become an established and routinely used imaging modality and has largely replaced invasive diagnostic digital subtraction angiography (DSA). There have been ongoing technical developments in magnetic gradient hardware, coil design and pulse sequence design for ce-MRA, resulting in an increased spatial and temporal resolution. The…

Peripheral arterial occlusive disease (PAOD) is a major health risk. The prevalence of PAOD varies with the population observed and the screening method used. In epidemiological studies, measurement of the ankle/brachial index (ABI) is recommended for screening (ABI <0.9 indicates PAOD). Surveys in Germany based on the ABI showed a PAOD prevalence of 2.3% among women aged 45–49 years and of 2…

Since the introduction in the early 1980s of magnetic resonance imaging (MRI) in clinical practice, contrast agents (CAs) have been part of MR studies enhancing the capabilities of this diagnostic technique. CAs enhance the contrast between different types of tissues. Tissue contrast depends largely on proton concentration and longitudinal (T1) and transversal (T2) relaxation times inherent to…

In recent years, magnetic resonance angiography (MRA) of the peripheral vascular tree has evolved into a widely available and valuable technique in the diagnostic and pre-interventional work-up of patients with peripheral arterial disease. Numerous studies have demonstrated the diagnostic accuracy of MRA for the assessment of abdominal and peripheral arteries, and in many hospitals the technique…

During the last few decades, the endovascular repair of aortic aneurysms (EVAR) has revolutionised the treatment of thoracic and abdominal aortic aneurysms. Since 1991, when Parodi et al.1 reported the first series of successful endovascular abdominal aneurysm repair in humans, enormous developments have been accomplished in techniques, materials and equipment. More delicate techniques and…
