If the padding is too little, the image will be affected by motion artifact, and if there is too much padding, the patient will complain of pain after about 20 min, resulting in suspension of the scanning. , not to move) is of paramount importance and ensure to talk to the patient during the scanning session for patients who are of nervous predisposition. If fat suppression is to be applied, pads that can compensate for magnetic field inhomogeneity should be used and try to position the coil in the center of the magnetic field as much as possible.
