摘要
目的 比较超声造影与增强螺旋CT评价急性胰腺炎严重度的准确性,探讨超声造影评价急性胰腺炎严重度的结果与临床指标的关系。方法 对33例72h内已行增强螺旋CT确诊的急性胰腺炎住院患者进行低机械指数实时超声造影(机械指数MI0.19),分别对增强螺旋CT及超声造影结果进行Balthazar’s分级,同时计算严重度指数(USSI,CTSI),比较分析二者与Ransons评分的相关性。结果 33例急性胰腺炎患者的USSI与CTSI及Ranson评分之间有一定的相关性(r=0.970,r=0.705;P<0.01)。结论 超声造影对急性胰腺炎的严重度评价有很好的作用,与临床参数评价有一定相关性,相对螺旋增强CT又具有简便、安全、禁忌症少等优点,可进行进一步研究。
Objective To compare diagnostic accuracy of contrast-enhanced ultrasound and contrast-enhanced spiral computed tomography（CT） in assessing the severity of acute pancreatitis, and to explore the correlation between nhrasound findings and clinical parameters. Methods Thirty-three patients with acute pancreatitis confirmed by contrast-enhanced CT within 72 were detected by contrast-enhanced ultrasound. Bahhazar＇s grading system was used to measure CT and ultrasound severity indices （CTSI and USSI ）. Correlations between CTSI and USSI and between USSI and clinical parameters （the Ranson score） were tested by Spearman＇ s rank correlation coefficient. Results A strong correlation was demonstrated between CTSI and USSI （r=0.970, P〈0.01 ）. Ultrasound findings were correlated with the Ranson score （r =0.705, P〈0.01 ）. Conclusion Contrast-enhanced ultrasound is effective and accurate in the assessment of acute pancreatitis severity. A significant correlation is observed between USSI and clinic parameters （Ranson score）. The procedure is more convenient, safer and has fewer contraindieations than contrast-enhanced CT.
