high resolution (8). In a study done by Bracher et al on UTE imaging for identification of carious lesions, the results revealed that there was not a proper delineation of the different layers of the teeth as well image degradation of dental fillings when compared to a conventional x-ray image. Few teeth depicted artifacts and superposition due

Dental MRI using wireless intraoral coils

concurrent imaging of many teeth with a voxel size of the order of (350 800 μm)3 15,18,35,36. In this work, we propose to use wireless, inductively-coupled intraoral volume coils for dental MRI

below 100µs, so they are suitable for teeth imaging (T 2 * of teeth is between 12µs 1ms for dentin [5] and High‐resolution ZTE imaging of human teeth. NMR

Magnetic resonance imaging of intraoral hard and soft tissues

In vivo imaging of two patients (29-year-old female and 35-year-old male) and ex vivo imaging of a dissected human mandible (provided by the Institute of Anatomy and Cell Biology of Albert-Ludwigs-University, Freiburg, Germany) was approved by the Ethics Committee of the Albert-Ludwigs-University of Freiburg (Application no. 338/13).

High-Resolution ZTE Imaging of Human Teeth

and efficiency of zero echo time (ZTE) MRI was used for high-resolution in-vitro imaging of human teeth and compared with UTE as well as micro computed tomography (µCT). Methods and Materials In ZTE imaging (Fig. 1), zero echo time is achieved by switching on the readout gradient before RF excitation with a high-bandwidth hard
