Figure 24. Right oblique sagittal T1 weighted spin echo image. The crown of the lower right first molar is missing and there is an area ofreduced signal at its apex (arrowed), probably owing to replacement of fatty marrow in the bone by inflammatory exudate. Similar areas of abnormality were seen in the left side of the mandible. The abnormality on MRI was considerably more extensive than on orthopantomogram and intraoral radiographs, and indicated the areas that required treatment.
