RF B₁ transmit field non-uniformity, caused primarily by skin depth and dielectric resonance effects, is a large source of error in quantitative MR measurements made at 3.0T. We investigated the possibility that B₁ errors could be reduced using dual transmission by measuring cervical cord MTR and B₁ with and without dual transmission.
