Nutation echoes are generated by radiofrequency (RF) pulses with an inhomogeneous amplitude, B 1 β«Ψβ¬ B 1 (r), in inhomogeneous magnetic fields, B 0 β«Ψβ¬ B 0 (r). The two gradients of strengths G 1 and G 0 , respectively, must be aligned in parallel for a maximum echo signal. After two RF pulses, two
## Abstract The magnetic field correlation (MFC) at an applied field level of 3 Tesla was estimated by means of MRI in several brain regions for 21 healthy human adults and 1 subject with aceruloplasminemia. For healthy subjects, highly elevated MFC values compared with surrounding tissues were fou
