WebMagnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, … WebThe echo time (TE) is twice the interpulse interval. The SE represents regeneration of spin phase information apparently lost during the decay of the FID. The "rebirth" of the FID as a SE is possible because many of the T2* processes which originally produced the decay of the FID are symmetrically reversible. In fact, most of the FID signal has ...
