A method for sensitising 3D UTE sequences to the short-$$$T_2$$$ range of cortical bone using scaled RF hard pulses has been previously demonstrated for creating CT-like contrast in MR imaging. However whole-volume excitation and encoding is not practical in all contexts. Here, an adaptation for slice-selective half-pulses is presented that enables 2D image encoding for MR-simulated-CT images.
