An intermediate weighted image is acquired by a sequence with a proton-density like long repetition time and a prolonged echo time usually 35-60 ms 1,2. It combines the ability to depict the detailed anatomy of a proton density-weighted image with the fluid sensitivity of a T2-weighted sequence, reducing significantly the occurrence of magic-angle artifacts at the same time.
