| Abstract: | A new method forT1ρcontrast in solid-state imaging is presented. The method is based upon the addition of aT1ρspin-lock pulse to the standard MARF pulse sequence and is able to provide relaxation contrast in dependence either on the lock time or on the intensity of the lock field, without having effects related to the line-narrowing procedure. The results on some large-linewidth solids show thatT1ρvalues measured by the usual spin-lock pulse sequence agree with those measured on space-resolved lines. |
