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

我们曾用分光光度法通过评估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评估的深度和厚度的皮下出血的瘀伤，准确地使用CT，OCT和超声检查。CT对帽状腱膜下血肿的检出是有用的，但不能检出皮下出血。OCT在观察皮肤层方面具有上级优势，能够检测到昆虫叮咬。超音波检查在皮下出血的诊断上是最具上级的，此外，我们还增加了一项特殊波长射线对陈旧性挫伤的显影研究。当我们用紫色的光线照射一个旧的瘀伤，并通过黄色的滤光片观察它时，我们甚至可以拍摄到受伤后几个月的瘀伤。这些研究的结果有助于我们及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.
