50例DR茎突摄影体位的探讨

Study of Radiographic Position of Styloid Process in 50 Cases with Digital Radiography

目的探讨茎突的最佳摄影体位,减小重照率。方法抽查50例DR茎突双侧摄影,传统的茎突侧位摄影法21例;茎突颈椎斜位摄影法29例。结果传统的茎突侧位摄影法成功率为59.5%,其中双侧为38.10%,单侧为42.8%;站立颈椎斜位摄影法成功率为79.3%,其中双侧为62.0%;单侧为34.4%。结论站立颈椎斜位摄影法优于传统的茎突侧位摄影法,一次成功率高且简便易掌握,便于临床诊断茎突过长及测量其长度。DR摄影技术的曝光宽容度大、图像分辨率高,可有效减小的照射量,降低对患者的辐射危害。

Objective To explore the best radiographic position of styloid process to reduce the re-irradiation rate. Methods 50 cases of bilateral styloid process photography were spot checked, concerning 21 conventional lateral styloid process photography and 29 oblique cervical vertebra position. Results The success rate of conventional lateral styloid process photography was 59.5%, among which 38.10% cases were bilateral, 42.8% were unilateral. The success rate of oblique standing position photography of cervical vertebra was 79.3%, a- mong which 62.0% were bilateral, and 34.4% were unilateral. Conclusions Oblique standing position of cervical vertebra, which has high one-time success rate, is better than conventional lateral styloid process photography. It is easy to learn and diagnose elongated styloid pro cess, and to measure its length simultaneously. Digital radiography has characters such as great exposure latitude and high resolution, which can significantly reduce exposure estimation and decrease patients＇ radiation risk.
