Contrast-enhanced multidetector computed tomography features and histogram analysis can differentiate ameloblastomas from central giant cell granulomas

Figure 1 Location of every lesion was classified into the following zones: 1, limited to the incisors; 2, limited to the canine and premolars; and 3, limited to the molars and posterior mandible. A similar classification was applied to the maxilla. Lesions extending over multiple zones were classified as such, and a suffix of R or L was used to denote right or left-sided location. When the lesion crossed the midline across multiple zones, + was used to denote the same.
