title: Age-dependent decrease in the computed tomographic numbers of parotid and submandibular salivary glands.
abstract: The computed tomographic (CT) numbers of 182 normal parotid glands were measured in patients ranging in age from 1 to 81 years, and of 172 normal submandibular glands with an age range of 1-85 years. The mean CT number (+/- s.d.) of the parotid and the submandibular glands was -10 +/- 24 Hounsfield units (HU) and 41 +/- is HU respectively. Sex and intra-individual differences in the CT numbers were small, but significant linear decreases were found with age in both glands. The mean annual decrease was 0.5 HU.
