Purpose In thiswork,we investigate if zero TE(zTE)imaging can be used as an alternative for dentistry imaging,for its similar to CT dense tissue contrast as well as excellent soft tissue contrast.Materials and Methods The patients that were diagnosed with horizontally erupted wisdom tooth using dental micro CT further received MRI scan.Zero TE imaging of the jaw was performed on a 3.0T whole body scanner(MR Discovery 750W)equipped with an 8 channel head neck coil.(Fig.1)Quantitative assessment was performed by measuring the relative separation of the root of the teeth to the mandible canal(MC)in both zTE image and CT image(Fig.2).The distance between the mandibular canal was manually measured using vendor supplied MR workstation.Results The sagittal and coronal view of zTE and CT images are shown in(Fig.3)respectively.Measurements of the distance between the upper,lower edge of the wisdom tooth and the MC on the sagittal view,between the root of a healthy tooth and the MC on the coronal view,obtained using both image contrasts are shown.It is seen that almost identical measurements were obtained.Hence the excellent contrast of the mandibular canal in zTE image allows the user to easily identify the separation from the root of the teeth; whereas computer aided contouring was needed in CT image to perform such measurement,due to the weak contrast of MC.conclusion Zero TE imaging has the advantage of being able to visualize the teeth that has a very short T2,and also is minimally affected by susceptibility in the oral cavity.As a result,much better contrast among the teeth,mandible,and mandible canal was obtained The distances measured between the teeth and the mandible canal were seen to be in excellent agreement with those obtained using CT.
