Graph shows three-dimensional UTE pulse sequence used to generate total and pore water images
by sampling two TEs in the same acquisition for in vivo studies. Dashed
vertical lines represent the switching delay from “transmit” mode
to “receive” mode. ADC = analog-to-digital
conversion, Gxyz = magnetic field gradients,
μs = μsec, RF =
radiofrequency pulses, tramp = ramp time,
tRF = radiofrequency pulse duration.
