概括

这项研究建立了怀孕早期胎囊体积 (ASV) 的参考间隔. 虚拟器官计算机辅助分析 (VOCAL) 方法比手动追踪对ASV测量更准确和可重复.

科学领域:

产科和妇科产科和妇科
医疗成像医学成像
胎儿医学胎儿医学

背景情况:

准确评估羊囊体积 (ASV) 对于监测早期怀孕至关重要.
在妊娠早期对ASV的确定的参考间隔是有限的.
对比超声波测量技术对于临床应用至关重要.

研究的目的:

为了确定怀孕7-12周之间的ASV的参考间隔.
为了比较手动超声波追踪的准确性,可重现性和临床实用性,与虚拟器官计算机辅助分析 (VOCAL) 进行ASV测量.

主要方法:

68个单独怀孕的前性观察研究.
使用手动跟踪和VOCAL超声波测量ASV.
统计分析包括回归,MAE,RMSE,ICC和布兰德-阿尔特曼分析.

主要成果:

ASV与妊娠年龄和皇冠长度 (CRL) 有着强烈的相关性.
声声显示出卓越的准确性 (MAE:0.35 cc;RMSE:0.6 cc) 和可重现性 (ICC>0.90).
手动追踪显示出显著的变化 (MAE: 16.94 cc; RMSE: 26.19 cc; ICC<0.50).

结论:

这项研究提供了早期怀孕的参考间隔.
VOCAL是一种可靠和精确的ASV评估方法.
手动方法虽然不太一致,但在资源有限的环境中对ASV评估是可行的.

Assessment of the Abdomen II: Percussion

Assessment of the Abdomen II: Percussion

Percussion is a fundamental technique used to assess the liver, spleen, and abdominal organs by tapping the abdomen and interpreting the resulting sounds. This method helps identify fluid, distention, and masses through variations in sound, such as the high-pitched tympany of air-filled areas and the dullness of solid masses. Understanding how to percuss these organs provides valuable information for healthcare professionals in diagnosing conditions early.
