$$$T_1$$$ mapping in MRI can be employed in a variety of techniques for diagnosis and treatment follow-up, but generally suffers from long acquisition times. Little effort has been put in low magnetic field regimes, where sensitivity is further impeded. Nevertheless, low field provides higher $$$T_1$$$ dispersion and favours adaptable scanner designs, suitable for dedicated applications such as MRI of body extremities. Here, we assess our newly developed interleaved, Look-Locker based $$$T_1$$$ mapping sequence in calibrated samples, and we present a first in vivo $$$T_1$$$ map of a volunteer’s hand at 0.1 T.
