MRI angiography (magnet resonance imaging angiography) is a non-invasive medical imaging technique that uses a magnetic field and radio waves to produce detailed images of blood vessels. The word 'angiography' is pronounced /ˌændʒɪˈɒɡrəfi/ with stress on the second syllable. 'MRI' is pronounced as individual letters, each pronounced /ɛm/ /ɑr/ /aɪ/. The combination of the two acronyms is spoken as /ˌɛmɑrˈaɪændʒɪˈɒɡrəfi/. The spelling might look difficult, but following the sounds make understanding this term much easier.
MRI angiography, also known as magnetic resonance angiography, is a noninvasive medical imaging technique that uses magnetic resonance imaging (MRI) technology to visualize blood vessels within the body. It provides detailed images of blood flow and blood vessels, allowing healthcare professionals to diagnose and assess the presence of any abnormalities or diseases.
During an MRI angiography, a contrast dye may be injected into the bloodstream to enhance the visibility of blood vessels. The MR scanner then uses a magnetic field and radio waves to create detailed images of the blood vessels in multiple planes and angles. This allows for the evaluation of any blockages, narrowing, or malformations in the blood vessels.
The procedure is commonly used to examine major arteries and veins in various parts of the body, including the brain, neck, chest, abdomen, and legs. It can aid in the diagnosis and monitoring of conditions such as stroke, aneurysms, vascular malformations, atherosclerosis, and thrombosis. MRI angiography is preferred over traditional angiography in many cases due to its noninvasive nature and its ability to provide high-resolution images without the need for radiation exposure.
MRI angiography is generally considered safe, although individuals with certain metallic implants or devices, such as pacemakers or cochlear implants, may not be eligible for the procedure. It is important for healthcare professionals to evaluate a patient's medical history and any potential risks before proceeding with an MRI angiography.
The word "MRI" is an abbreviation for Magnetic Resonance Imaging, which refers to the medical imaging technique that uses strong magnets and radio waves to create detailed images of the body's internal structures. It was originally known as Nuclear Magnetic Resonance (NMR) imaging, but the term "nuclear" was dropped from the name to avoid negative connotations associated with radiation in the public perception.
The term "Angiography" also consists of two components. "Angio" comes from the Greek word "angeion", meaning "vessel", while "graphy" is derived from the Greek word "graphia", meaning "writing" or "recording". Therefore, "Angiography" refers to the process of imaging and visualizing blood vessels in the body.
