目的 探讨16层螺旋CT容积再现、表面遮盖法重建、多平面重建技术及最大密度投影技术在成人茎突测量中的应用及对茎突综合征(SPS)诊断的价值.方法 回顾性分析50例86侧临床诊断为SPS患者的16层螺旋CT及容积再现、表面遮盖法重建、多平面重建、最大密度投影重组资料,并测量茎突的长度及方位角.结果 茎突长度大于3 cm者69侧(80.2％),分节型茎突者45侧(52.3％),茎突向内偏斜角＞25°者36侧(41.9％),向前偏斜角＞25°者5侧(5.8％).结论 茎突过长、茎突发育呈分节型和方位角异常是诊断SPS的重要依据.多层螺旋CT的容积再现、表面遮盖法重建、多平面重建、最大密度投影重组可为诊断SPS提供重要依据.
目的 探討16層螺鏇CT容積再現、錶麵遮蓋法重建、多平麵重建技術及最大密度投影技術在成人莖突測量中的應用及對莖突綜閤徵(SPS)診斷的價值.方法 迴顧性分析50例86側臨床診斷為SPS患者的16層螺鏇CT及容積再現、錶麵遮蓋法重建、多平麵重建、最大密度投影重組資料,併測量莖突的長度及方位角.結果 莖突長度大于3 cm者69側(80.2％),分節型莖突者45側(52.3％),莖突嚮內偏斜角＞25°者36側(41.9％),嚮前偏斜角＞25°者5側(5.8％).結論 莖突過長、莖突髮育呈分節型和方位角異常是診斷SPS的重要依據.多層螺鏇CT的容積再現、錶麵遮蓋法重建、多平麵重建、最大密度投影重組可為診斷SPS提供重要依據.

Objective To evaluate the value of styloid process measurement using 16-detector row spiral CT with volume rendering,shaded surface display,multi-planar reconstruction and maximum intensity projection reconstruction techniques in the diagnosis of adult styloid process syndrome (SPS).Methods 16-detector row spiral CT with volume rendering,shaded surfaee display,multi-planar reconstruction and maximum intensity projection reconstruction techniques were used in 50 patients (86 sides) with clinically suspected SPS,the length and deviated angle of styloid process were measured.Results In these 86 sides of styloid process,69 sides showed the length longer than 3 cm (80.2％),45 sides showed segmented styloid process (52.3％),the oblique angle of styloid process was deviated interually more than 25° in 36 sides (41.9％),and deviated anteriorly angle more than 25° in 5 sides (5.8％).Conclusion Over-length,segmentation and abnormal deviation of the oblique angle of styloid process are important criteria in the diagnosis of SPS,helpful information could be provided by multiple-detector spiral CT with volume rendering,shaded surface display,multi-planar reconstruction and maximum intensity projection reconstruction techniques.
