A noninvasive technique that uses the phenomenon of magnetic resonance to obtain information on the structure and composition of the body to be analyzed. This information is processed by a computer and transformed into images of the inside of what has been analyzed. It is mainly used in medicine for abnormal changes in tissues and detect cancer and other diseases. It is also used industrially to analyze the structure of both organic and inorganic materials. MRI machines are machines with many components that are integrated with great precision to obtain information on the distribution of atoms in the human body using the phenomenon of RM. The system's main component is a magnet capable of generating a constant magnetic field of large intensity. The constant magnetic field is responsible for aligning the magnetic moments of atomic nuclei mainly in two directions, parallel (vector pointing in the same direction) and anti-parallel (pointing in opposite directions). The field strength and magnetic moment of the nucleus determines the resonant frequency of the nuclei, and the proportion of nuclei found in each of the two states.
