Abstract: Objective  To explore the clinical value of ultrasonography in the early diagnosis of idiopathic precocious puberty in girls.Methods  Fifty seven girls suspected with idiopathic central precocious puberty admitted to our hospital from March 2018 to October 2019 were selected as the observation group, and 57 healthy girls at the same age range were selected as the control group. Both groups were given breast and pelvic high frequency ultrasonography and relevant hormone level examination.Results (1) Breast high frequency ultrasonography showed: the length and thickness of the observation group in the peripheral gland echo area and the central hypoecho area of the breast were higher than those of the control group, and the difference was statistically significant (P＜0.05). (2) Pelvic high frequency ultrasonography showed: the observation group was higher in ovarian volume, anterior and posterior diameter of the ovary, transverse diameter of the ovary, long diameter of the ovary, and follicle diameter than the control group, and the difference was statistically significant (P＜0.05). (3) Examination of relevant hormone levels showed: the levels of estradiol, follicle stimulating hormone, and luteinizing hormone in the observation group were higher than those in the control group, and the difference was statistically significant (P＜0.05). Conclusion  Color Doppler ultrasonography has high clinical application value in the diagnosis of girls with idiopathic central precocious puberty, with clear diagnostic criteria and relatively mature and stable technology.
