The objective of this pilot study was to test the feasibility of automating the detection of abdominal free fluid in focused assessment with sonography for trauma (FAST) examinations. Perihepatic views from 10 FAST examinations with positive results and 10 FAST examinations with negative results were used. The sensitivity and specificity compared to manual classification by trained physicians was evaluated. The sensitivity and specificity (95% confidence interval) were 100% (69.2%-100%) and 90.0% (55.5%-99.8%), respectively. These findings suggest that computerized detection of free fluid on abdominal ultrasound images may be sensitive and specific enough to aid clinicians in their interpretation of a FAST examination.
这项初步研究的目的是测试在创伤重点超声评估(FAST)检查中自动检测腹腔游离液体的可行性。使用了10例结果为阳性的FAST检查和10例结果为阴性的FAST检查的肝周视图。评估了与训练有素的医生进行手动分类相比的敏感性和特异性。敏感性和特异性(95%置信区间)分别为100%(69.2%-100%)和90.0%(55.5%-99.8%)。这些发现表明,腹部超声图像上游离液体的计算机检测可能足够敏感和特异,有助于临床医生对FAST检查进行解读。
