Explanations on the Topic „Relaxation and Precession of a Spin in MRI“
The spin can be influenced by magnetic fields or RF pulses. In a static homogeneous magnetic field, it precesses around the direction of the magnetic field at the Larmor frequency. Through a relaxation process, it aligns with the direction of the external field after a certain time, which is determined by the so-called longitudinal relaxation time T1.
In a microwave field (RF pulses), the spin direction can be altered in short periods of time. For tissue studies (determining T1 and T2), deflections of 90° or 180° from the stationary field direction have proven to be advantageous.
