【摘要】 目的 :探讨彩色多普勒超声对慢性胃炎的诊断价值。方法 :对经胃镜、胃 B超诊断为慢性胃炎患者5 1例 ,正常对照组 15例的胃粘膜血管行彩色多普勒超声检测。结果 :5 1例慢性胃炎患者在胃小弯侧粘膜检测到动脉频谱 30例 ,占 5 8.8% ,对照组 15例中仅检出 1例 ,占 6 .7%。其收缩期峰值速度 (2 4.9± 11.8) cm/ s,舒张末期速度 (8.3± 3.6 ) cm/ s,搏动指数 0 .99± 0 .2 1,阻力指数 0 .6 6± 0 .0 9。结论 :胃粘膜血管的彩色多普勒超声检测与胃B超检查相结合 ,提高了慢性胃炎的诊断准确性。更多还原

【Abstract】 Objective:To evlauate the diagnostic role of color Doppler flow imaging (CDFI)for chronic gastritis.Methods:Data of the gastric mucosal vessels in 51 cases with chronic gastritis and 15 normal persons were measured by CDFI.Results:Blood flow signals were detected in one of 15 normal persons(6 7%)and in 30 of 51 cases with chronic gastritis(58 8%)in the mucosa of gastric lesser curvature.The systolic peak velocity(Vs)was(24 9±11 8)cm/s,end diastolic velocity(Vd)(8 3±3 6)cm/s pulsatility index(PI)0 99±0 21 and resistance index(RI),0 66±0 09.Conclusions:The diagnostic accuracy of chronic gastritis could be improved by integration of B mode ultrasonography with CDFI of the gastric mucosal vessels.更多还原
