The objective of this study was to compare 3 imaging techniques-plain radiography, soft-tissue radiography, and ultrasonography-in detecting nonradiopaque foreign bodies in soft tissue.
In this randomized, blinded, and descriptive in vitro study, 40 chicken thighs with 2 types of nonradiopaque foreign bodies (wood and rubber) and 40 chicken thighs as part of a control group were evaluated to detect soft-tissue foreign bodies with plain radiography, soft-tissue radiography, and high-frequency ultrasonography.
The overall sensitivity, specificity, as well as positive predictive and negative predictive values of plain radiography for both nonradiopaque foreign bodies were 5%, 90%, 33%, and 48%, respectively; those of soft-tissue radiography for both nonradiopaque foreign bodies were 5%, 90%, 33%, and 48%, respectively; and those of ultrasonography for both nonradiopaque foreign bodies were 90%, 80%, 81%, and 89%, respectively.
In this experimental model, the results show that high-frequency ultrasonography is superior to plain and soft-tissue radiographies and that the latter 2 techniques are similarly poor at detecting nonradiopaque foreign bodies.
本研究的目的是比较三种成像技术——普通X线摄影、软组织X线摄影和超声检查——在检测软组织中不透射线异物方面的效果。
在这项随机、双盲的描述性体外研究中，对40条带有两种不透射线异物（木头和橡胶）的鸡大腿以及作为对照组的40条鸡大腿进行评估，以通过普通X线摄影、软组织X线摄影和高频超声检查来检测软组织异物。
普通X线摄影对两种不透射线异物的总体敏感度、特异度、阳性预测值和阴性预测值分别为5%、90%、33%和48%；软组织X线摄影对两种不透射线异物的上述指标分别为5%、90%、33%和48%；超声检查对两种不透射线异物的上述指标分别为90%、80%、81%和89%。
在该实验模型中，结果表明高频超声检查优于普通X线摄影和软组织X线摄影，而后两种技术在检测不透射线异物方面同样效果不佳。
