Evaluation of Parotid Glands With Real-time Ultrasound Elastography in Children
Objectives-The aim of this study was to determine the strain index for
parotid glands in children by using ultrasound elastography.
Methods-In this prospective study, apparently healthy children were
referred from the ear-nose-throat clinic to the radiology clinic for
elastographic examinations. Conventional sonographic and elastographic
examinations of the parotid glands were performed. A linear 5-12-MHz
transducer was used to obtain the images.
Results-A total of 54 children were enrolled in this prospective study.
The normal mean strain index value +/- SD for the parotid glands was
1.24 +/- 0.67 (range, 0.29-1.39) regardless of sex. The mean age of
girls was 7.42 +/- 2.94 years (range, 3-14 years), and the age of boys
was 8.50 +/- 3.46 years (range, 4-16 years). The strain index values for
the parotid glands in boys was 1.25 +/- 0.76, and in girls it was 1.22
+/- 0.55. There was no statistically significant difference in the
strain index values between girls and boys (P=.986). There was no
correlation between the strain index and age (r = 0.026) or body mass
index (r = 0.066).
Conclusions-This study determined the mean strain index values for
apparently healthy children. Such information can serve as a baseline
from which pathologic parotid diseases can be diagnosed with ultrasound
elastography in combination with other sonographic criteria
