ZTE is a novel MRI sequence which can be used for the imaging of the bone. In this pilot study we present our initial experience with this sequence. The pseudoCT images generated after post-processing of raw ZTE data were similar to the real CT images in bone windows and were able to give the relevant clinical information about the lesion size, margins, erosions and bony expansion. As this technique is free of ionising radiation, it has a huge potential for bone imaging. Thus the MRI becomes one stop shop for the imaging of patients with bone lesions.
