Diagram of the 2D UTE sequence for lung T2* measurement. The sequence combines FID radial acquisition, half-sinc RF pulse excitation, ramp sampling and VERSE techniques to achieve an ultrashort echo time below 100us. δ (150us): ramp-down time of slice selective gradient; τ1 (30us): duration of ADC in advance of the readout gradient; τ2 (150us): ramp-up time of the readout gradient.
