| 摘 要：［目的］ 探讨瞬时弹性成像系统在胃肠道间质瘤术前诊断中的价值。［方法］ 2014年2月至2016年8月盆腔肿物患者60例作为研究对象，均行常规超声与瞬时弹性成像系统检查，判定诊断效果与检查特征。［结果］ 60例患者经过病理诊断为胃肠道间质瘤35例，诊断为非胃肠道间质瘤25例。胃肠道间质瘤35例中超声表现为低回声32例，伴后方声影27例，内部血流丰富23例，轮廓模糊24例；非胃肠道间质瘤25例中超声表现为低回声8例，伴后方声影6例，内部血流丰富9例，轮廓模糊5例，两组超声特征对比差异有统计学意义(P<0.05)。胃肠道间质瘤患者的瞬时弹性成像参数AT、TTP值明显低于非胃肠道间质瘤患者(P<0.05)，而T1/2、AUC与EI值明显高于非胃肠道间质瘤患者(P<0.05)。常规超声诊断胃肠道间质瘤的敏感性与特异性分别为80.0%和92.0%，而瞬时弹性成像系统的敏感性与特异性分别为97.1%和100.0%，瞬时弹性成像系统的敏感性高于常规超声(P<0.05)。［结论］ 瞬时弹性成像系统在胃肠道间质瘤术前诊断中的应用是一种安全、无损伤的检查，可动态观察，而且对胃肠道间质瘤的生长特征、内部结构定判断具有重要价值。 |

| Abstract：［Objective］ To investigate the value of transient elastography in preoperative diagnosis of gastrointestinal stromal tumors(GIST). ［Methods］ Sixty cases of pelvic mass in our hospital were selected from February 2014 to August 2016，.All were given the conventional ultrasound and the transient elastography diagnosis and to determine the diagnostic effect and characteristics. ［Results］ Totally，sixty cases with pathologically diagnosedwere retrospectively investigated，，including 35 with GIST，25 ofnon- GIST. In the GIST patients，there were 32 cases of ultrasound showed hypoechoic，27 with acoustic shadows，23 with internal rich blood flow，24 with non gastrointestinal fuzzy contour；25 withgastrointestinal stromal tumor；and in the non- GIST patients，8of ultrasound showed hypoechoic，6with acoustic shadows，9 with rich internal blood flow，5 with exudative shadow，The ultrasound characteristics of two groupswere significantly difference(P<0.05). The values of AT and TTP in the patients with GIST were significantly lower than those of non-GIST(P<0.05)，while the T1/2，AUC and EI values were significantly lower than those of non-GIST(P<0.05). The sensitivity and specificity of conventional ultrasound in the diagnosis of GIST were 80.0% and 92%，and the sensitivity and specificity of transient elastography for the diagnosis of GIST were 97.1% and 100%，both were higher in transient elastographygroupthan that of conventional ultrasound group(P<0.05). ［Conclusions］ Transient elastography system in preoperative diagnosis of GIST is a safe，noninvasive imaging，it can dynamic observation and has important value for the internal structure of GIST growth characteristics. |
