Trial to diagnose physical abuse by visualizing the subcutaneous hemorrhage of a bruise

我们用分光光度法通过评价瘀伤的颜色来估计瘀伤的年龄，发现皮下出血的深度和厚度对瘀伤的颜色变化有很大的影响。我们确定我们是否可以准确地评估擦伤皮下出血的深度和厚度使用CT， OCT和超声。CT可检出galeal下血肿，但不能检出皮下出血。OCT在皮肤层的观察上有优势，能够发现昆虫叮咬。超声检查是诊断皮下出血的最优方法。此外，还增加了用特殊波长射线对旧瘀伤的可视化研究。当我们用紫色光线照射旧的瘀伤，并用黄色滤光片观察它时，我们甚至可以拍摄到受伤几个月后的瘀伤。这些研究的结果有助于我们尽早保护受虐待的儿童。

We have used spectrophotometry to estimate the age of a bruise by evaluating the color of a bruise, and found that the depth and thickness of the subcutaneous hemorrhage have a great influence on color changes of a bruise. We determined whether we could evaluate the depth and thickness of the subcutaneous hemorrhage of a bruise precisely using CT, OCT and ultrasonography. CT was useful to detect subgaleal hematoma, but was not able to detect subcutaneous hemorrhage. OCT was superior in observation of the cutaneous layer, and was able to detect an insect bite. Ultrasonography was the most superior in a diagnosis of the subcutaneous hemorrhage.Furthermore, a study of the visualization of an old bruise by special wavelength rays was added. When we illuminated an old bruise with purple rays and observed it by a yellow filter, we could photograph even the bruise that several months passed since they were injured. The result of these studies helps that we protect abused children early.
