儿童手腕骨折是急诊科常见的损伤。大约50%的X光片显示没有骨折。本研究的目的是开发一种使用红外热成像（IRTI）数据和多层感知器（MLP）神经网络作为筛选工具的模型，以帮助临床医生决定哪些患者需要X射线成像来诊断骨折。纳入40例腕关节损伤的受试者（19例骨折，21例无骨折，X线证实），平均年龄10.50岁。以对侧手腕为参考，进行双侧手腕的IRTI。对腕关节损伤感兴趣区域（ROI）进行分割，并以10 × 10像素的单元格表示。选择50个最大的平均值，减去对侧ROI的平均温度，并用标准差、峰度和四分位距表示，以进行MLP处理。创建培训和测试文件，分别由随机分配的2/3和1/3的参与者组成。为了避免参与者包含在两个文件中的偏差，实验重复100次，并对MLP输出进行平均。模型的敏感性和特异性分别为84.2%和71.4%。进一步的工作涉及更大的样本量，成人和其他骨折。
Paediatric wrist fractures are commonly seen injuries at emergency departments. Around 50% of the X-rays taken to identify these injuries indicate no fracture. The aim of this study was to develop a model using infrared thermal imaging (IRTI) data and multilayer perceptron (MLP) neural networks as a screening tool to assist clinicians in deciding which patients require X-ray imaging to diagnose a fracture. Forty participants with wrist injury (19 with a fracture, 21 without, X-ray confirmed), mean age 10.50 years, were included. IRTI of both wrists was performed with the contralateral as reference. The injured wrist region of interest (ROI) was segmented and represented by the means of cells of 10 × 10 pixels. The fifty largest means were selected, the mean temperature of the contralateral ROI was subtracted, and they were expressed by their standard deviation, kurtosis, and interquartile range for MLP processing. Training and test files were created, consisting of randomly split 2/3 and 1/3 of the participants, respectively. To avoid bias of participant inclusion in the two files, the experiments were repeated 100 times, and the MLP outputs were averaged. The model’s sensitivity and specificity were 84.2% and 71.4%, respectively. Further work involves a larger sample size, adults, and other bone fractures.
