MR TOMOGRAPHY Meaning and
Definition
-
MR Tomography, also known as Magnetic Resonance Tomography or Magnetic Resonance Imaging (MRI), is a medical imaging technique that generates detailed images of the body's internal structures using magnetic fields and radio waves. It offers a non-invasive, safe, and highly accurate method to visualize various anatomical and physiological aspects of the human body.
MR Tomography involves placing the patient within a strong magnetic field generated by a large cylindrical magnet. When exposed to this magnetic field, the hydrogen atoms within the body align themselves in a specific direction. Radiofrequency pulses are then applied, causing the hydrogen atoms to emit signals. These signals are captured by specialized detectors and processed by a computer to construct detailed cross-sectional images of the body.
The resulting MR images provide high spatial resolution, allowing for precise visualization of soft tissues, organs, and structures. It offers a versatile diagnostic tool across various medical fields, including neurology, cardiology, orthopedics, and oncology.
MR Tomography eliminates the use of harmful radiation, making it a safe imaging modality for pregnant women and pediatric patients. Furthermore, it enables the imaging of multiple planes and an array of imaging sequences, facilitating the assessment of blood flow, tissue composition, and certain physiological functions.
In summary, MR Tomography is a non-invasive diagnostic imaging technique that utilizes magnetic fields and radio waves to produce high-resolution images of the body's internal structures. It provides valuable information to aid in the diagnosis, treatment planning, and monitoring of various medical conditions.

Etymology of MR TOMOGRAPHY
The word "MR Tomography" is derived from "magnetic resonance tomography".
"Magnetic resonance" refers to the physical phenomenon known as nuclear magnetic resonance (NMR), which was discovered in the 1940s. NMR involves the interaction of atomic nuclei with strong magnetic fields and radio frequency pulses to generate a signal that can be used to create detailed images of the internal structure of objects.
In the medical field, the term "tomography" refers to a technique used to visualize cross-sectional images of the human body. This technique is achieved by taking multiple X-ray images of a patient from different angles and then using a computer to reconstruct a three-dimensional image.
When applied to medical imaging, "magnetic resonance tomography" (MRT) or "magnetic resonance imaging" (MRI) is the use of NMR technology to generate detailed images of the human body without the use of X-rays.
