Magnetic Resonance Imaging Study Promises Accurate Imaging of Many Abnormalities
Magnetic resonance imaging (MRI) is an advanced imaging technique by physicians can visualize detailed internal structure and limited function of the body. This technology can produce greater contrast between different soft tissues of the body than other imaging technologies like computed tomography, ultrasound and X-ray. Magnetic resonance imaging study is useful in neurological (brain), cardiovascular, musculoskeletal, and oncological imaging. There is a powerful magnetic field to align the nuclear magnetization of hydrogen atoms in water in the body. Photons are the carriers of electromagnetic fields, and electromagnetism. These photons travel in as much as light is composed of photons.
The MRI machine uses a radio frequency transmitter that produces an electromagnetic field. The photons of this field have just the right energy. This imaging technology was developed from knowledge gained in the study of nuclear magnetic resonance. Initially, it was referred as nuclear magnetic resonance imaging (NMRI). Radio frequency fields are used to systematically alter the alignment of this magnetization. The ionizing radiation exposure is found through magnetic resonance imaging. The signal produced by the magnetic field can be manipulated to generate enough information to construct an image of the body.
Magnetic resonance angiography (MRA) can generate pictures of the arteries in order to examine them for stenosis or aneurysms. The MRI scan is an accurate method of disease detection throughout the body. The magnetic resonance imaging study includes many abnormalities of the body such as brain aneurysms, stroke, tumors and inflammation of the spine. Its study also provides valuable information on glands and organs within the abdomen, and valuable information about the structure of the soft tissues, joints, and bones of the body.
