High frequency ultrasound inspection of T7-8 paravertebral space and adjacent structures / 中国医学影像技术

ABSTRACT

Objective To observe value of high frequency ultrasound for inspection of T7-8 paravertebral space and adjacent structures.Methods Color Doppler ultrasonic diagnostic apparatus with linear array transducer (frequency 3-12 MHz) were used.Taking shoulder blade,ribs,thoracic spine and transverse process as anatomical marks,T7-8 paravertebral spaces of 30 normal adult (a total of 60 side) were examined.Ultrasonographic features of T7-8 paravertebral space and the adjacent structures were observed.Results T7-8 thoracic paravertebral showed as similar triangular shape with ultrasonography,interior solid homogeneously hypoechoic was noticed.Adjacent muscles of T7-8 paravertebral space included the trapezius,latissimus dorsi,spinalis,semispinalis,multifidus,rotatores and intercostal muscles.Color Doppler or power Doppler flow imaging could demonstrate posterior intercostal artery in the paravertebral space.Conclusion High frequency ultrasound can clearly show T7-8 paravertebral space and adjacent structures,thus providing ultrasonic references for clinical diagnosis and treatment of lesions of thoracic space and adjacent structures.
