MRI with zero echo time (ZTE) was implemented for efficient, robust, and silent high-resolution 3D imaging of short-T2 samples. The technique was applied for MRI of extracted human teeth, yielding detailed depictions with very good delineation of the mineralised layers. ZTE results were compared with UTE (ultra-short echo time) MRI, revealing significant differences in SNR and CNR yield. Compared to micro-computed tomography, ZTE MRI indicates to offer superior sensitivity for the detection of early demineralisation and caries lesions.
