From: Computed tomographic features of adenoid cystic carcinoma in the palate
Computed tomographic images of cases with or without GPF enlargement. The diameters of the left and right GPFs were measured in bone window (upper layer: horizontal level; lower layer: coronal reconstruction). (a) No.35 patient was considered without GPF enlargement (GPF diameter on the tumor side was 0.2 mm larger than that on the normal side). (b) No.13 patient was considered with GPF enlargement (GPF diameter on the tumor side was more than 0.3 mm larger than that on the normal side). (c) NO. 71 patient was considered as GPF enlargement (complete destruction of GPF on the tumor side). GPF = greater palatine foramen
