MR imaging of teeth using a silent single point imaging technique
Source abstract
Abstract
Magnetic resonance imaging (MRI) of teeth is an emerging application area which is still in development. Previous investigations did not fully focus on potential in vivo applications. Using 1H and 31P MRI, we obtained ex vivo microimages of teeth with a silent single point imaging (SPI) technique. 1H Images with an in-plane resolution of 310×310 μm2 were obtained. Utilizing sine-shaped gradient ramps significantly reduced the sound pressure level of the experiment to that of background noise. 1H magnetic resonance spectroscopy (MRS) was used to characterize the major components in the observed resonance. The spin–spin (T2) relaxation times of water in enamel and dentin differed by at least one order of magnitude. Three-dimensional surface reconstruction of the data allowed for complete visualization of the tooth’s surface while volume reconstruction displayed the internal geometry.
