Study Notes
MRI Basics
- MRI stands for Magnetic Resonance Imaging
- MRI is based on the physical phenomenon of Nuclear Magnetic Resonance (NMR)
MRI Principle and Procedure
- The principle behind MRI is Resonance
- MRI is a non-invasive technique in the field of radiology
- The MRI procedure is a non-invasive procedure that uses magnetic fields and radio waves
- MRI uses magnetic fields and radio waves to create images of organs and tissues
MRI Characteristics
- MRI uses radio waves to create images
- MRI does not use ionizing radiation
- MRI produces cross-sectional images
- Claustrophobic design is a characteristic of MRI that may cause anxiety in some patients
MRI Physics
- The powerful magnetic field in MRI is used to align hydrogen nuclei
- The unit of measurement for MRI flux density in SI units is Tesla (T)
- The unit of measurement for MRI flux density in CGS units is Gauss (G)
MRI Machine and Computer Program
- The machine used in MRI is called an MRI scanner
- The computer program in MRI is used to create high-quality images
Advantages and Purpose
- The advantage of MRI over CT scans is that it uses non-ionizing radiation
