Recent studies have shown the accuracy of a VIBE sequence in visualizing the mandibular canal compared to X-ray based methods. In order to increase resolution without unnecessarily lengthen acquisition time a small field of view is needed. This can be achieved by using regional saturation bands in VIBE or local look technique in TSE sequences to avoid aliasing artifacts. Since TSE offers higher SNR and in combination with local look technique is more comfortable to set up, we compared both methods by calculating the surface difference of the mandibular canal.
