Objective To explore the characteristics of normal tongue ultrasonic image feature.Methods 56 volunteers of tongue healthy were selected, whose oral contained 36℃ warm water about 30ml and with setting posture.Real-time high- frequency and abdominal probes were parallelly and sequentially scaned their tongue from the percutaneous suprahyoid area.The transverse and longitudinal sectiones of the tongue were obtained and measured.CDFI was used to observe the course and distribution of the tongue’s blood vessel ,and relationships among diameter,peak speed(PS) and resistance index (RI) were ananlyzed. Result The ultrasonic images of the main normal structure of the tongue were clearly displayed. The length of the tongue were (58.91 ± 6.38) mm. The widths and thickness of the root and body were (37.59 ±4.57) mm 、(43.02±5.00）mm and (32.61± 5.30) mm、（39.01±4.49）mm. The right and left lingual artery peak velocity were( 32.71 ±9.61) cm/s and ( 31.89 ± 8.79) cm / s, the RI both were (0.75 ± 0.06),the inner diameter were (1.81±0.14) mm and(1.78 ±0.13) mm.The right and left venous velocity were(10.03 ±3.48) cm / s and ( 10.38 ±4.08)cm / s,the inner diameter were (2.03 ±0.14) mm and (2.02 ± 0.14) mm. Conclusion Oral contains about 30ml warm water( 36℃)in sitting posture， use real-time high- frequency and abdominal probes from the percutaneous suprahyoid area to check the tongue can obtain complete ultrasonic anatomical sectional drawing of the tongue and color flow mapping. The research results mentioned in this paper will provide an important uitrasonic anatomic basis for ultrasound diagnosis of the located lesions of the tongue.
