Subject Magnetic Resonance Imaging; MRI; Nuclei Magnetic Field; Nuclear Stability; Magnetic Field Strength; Nuclear Properties; Magnetization; Maximal Signal; Time Intervals; Spin Echo
Description Nuclei in a magnetic field: A . Nuclei contain protons and neutrons that spin at high speed. 1. Proton (+) 2. Neutron (-) 3. Spin generates a magnetic field 'magnetic moment' 4 . Paired nuclei a. Equal protons (+) and neutrons (-) b . Cancel each other - no MM 5. Unpaired nuclei a. Unequal protons relative to neutrons b . Magnetic moment produced c. Hydrogen - one proton (strong field) d. Acts as a bar magnet. 1. Aligns in a magnetic field 2. Points with the magnetic field (parallel) or against the magnetic field (anti-parallel)
