Nuclear Magnetic Resonance Imaging Promises to Produce Quality Images of the Body Organs
Magnetic resonance imaging, or nuclear magnetic resonance imaging (NMRI) is a special branch of radiology that refers to a medical imaging technique to visualize the internal structure and limited functions of the body organs. This technology promises to cater much greater contrast between different soft tissues of the body than computed tomography (CT) dose and x-ray. It is very useful in neurological, musculoskeletal, cardiovascular and oncological imaging. With the help of powerful magnetic field, the MRI technique can align the nuclear magnetization of hydrogen atoms in water in the body.
In MRI, radio frequency (RF) fields are used to systematically alter the alignment of this magnetization. The process results in the generation of a rotating magnetic field that can be detected by a scanner. The nuclear magnetic resonance imaging procedure applies non-invasive technique and relies on the magnetic properties of atoms, rather than radiation that is used in many other imaging procedures. The produced signals can be manipulated by additional magnetic fields to build up enough information to construct image of the body parts.
The NMRI experts use their communication, patient care and collaborative skills. They are responsible to ascertain the safety of each individual in the magnetic resonance environment before entering the magnetic field. These technologists are patient advocates who display the strong problem solving and technical skills. Nuclear magnetic resonance imaging technology is used to conduct tests on various body parts that include abdominal test, chest, cranial, heart, lumbosacral spine, etc. This test is completely safe procedure and does not show any form of physical side effects. However, there may be some temporary ones like sudden flushing and tingling sensation during test.
