Manual three-dimensional segmentation of a basal cell adenoma in a 65-year-old female. (a) segmentation on the axial slice. (b) three-dimensional volumetric reconstruction. (c) Case 1: pleomorphic adenoma of the left parotid gland in a 66-year-old female (white arrow). The mass shows mild contrast enhancement at the arterial phase, with CT value of 27–44 HU. (d) Case 2: Warthin tumor of the right parotid gland in a 68-year-old male (white arrow). The mass shows marked contrast enhancement at the arterial phase, with CT value of 90–110 HU. (e) Case 3: basal cell adenoma of the right parotid gland in a 65-year-old female (white arrow). The mass shows marked contrast enhancement at the arterial phase, with CT value of 90–140 HU.
