Noninvasive modalities, including duplex ultrasonography, renal scintigraphy, CT angiography and magnetic resonance angiography (MRA), may usefully contribute to diagnosis and treatment planning in ...

Peripheral arterial disease (PAD) is a common manifestation of systemic atherosclerosis. Although clinical history in conjunction with ankle–brachial index and evaluation of segmental ...

A new heart scan is faster and has lower radiation exposure than MRI and invasive angiography, according to a study published in Circulation: Cardiovascular Imaging. Researchers compared three ...

Doctors may use an MRI scan to detect a brain aneurysm in specific cases. MRI scans and other imaging techniques can help detect a brain aneurysm and reveal its shape and precise location. A brain ...

In patients with stable angina, two strategies are often used to guide revascularization: one involves myocardial-perfusion cardiovascular magnetic resonance imaging (MRI), and the other involves ...

A new type of imaging technique using an MRI device can detect most diseased coronary arteries, potentially sparing many heart patients a more invasive, expensive and uncomfortable test, researchers ...

Magnetic resonance imaging is increasingly used to avoid the radiation used in computed tomographic scanning. Gadolinium contrast medium allows vascular imaging without the nephrotoxic effects ...

The "gold standard" for detection of CAD remains invasive angiography with vessel-selective contrast injection of the coronary arteries. Both spatial (0.2 mm) and temporal (5 ms) resolution of the ...

Special Operations Forces personnel, researchers found that a higher prevalence of intracranial aneurysms was independently associated with greater repeated blast exposure. Results of the study were ...
