目的：在红外热成像技术筛检发热的基础上研究其对咽喉部炎症的探测作用。方法选用非制冷焦平面红外热象仪，温度分辨率0.05℃，采集速度30帧/s。采用双盲法，即检测人员和受检者均互不知晓红外和体检情况。随机采集集训新兵118例，根据口咽部的体检体征（即扁桃体肿大及咽喉充血情况），由临床医生将受试者分为急性扁桃体炎（n=33）、急性咽喉炎（n=60）和正常对照（n=25）3组。根据红外热图像的表达进行定位评价，提取咽喉部相对应体表区域的最高温、最低温和平均温的温度值，进行定量比较分析。结果正常组红外表达为大片状绿色凉区或蓝色冷区；而扁桃体炎与咽喉炎组在咽喉部相对应的体表区域可见明显异常的红外热图表达，两组表达的红外热像图分布相近，均表现为口咽部对应区域斑片状、条索状等多形状的弥漫性或灶性的粉色热区或红色高热区。急性扁桃体炎组、急性咽喉炎组下颌下区、咽喉区最高温、最低温及平均温均高于正常对照组（均P<0.05），但是急性扁桃体炎组与急性咽喉炎组间比较差异没有统计学意义。结论急性扁桃体炎与急性咽喉炎可在体表相对应的区域呈现明显异常的红外热图表达；与正常比较，红外热成像检测对咽喉部急性炎症高度敏感。

Objective To determine the usefulness of infrared thermal imaging(IRTI)technique in detecting laryngopharyngitis based on its capacity in screening fever. Methods Uncooled focal plane?infrared thermal imager with 0.05℃temperature resolution and 30 frames/s acquisition speed was used in the study. The double blind design of the study was set to ensure that both the investigator and study subjects did not know the condition of infrared and physical examination. A total of 118 recruits were randomly included as the subjects in the study. According to the inspected signs at the oropharynx (tonsillar enlargment and throat congestion),all subjects were divided into 3 groups,namely,the acute tonsillitis group (n=33), acute laryngopharyngitis group(n=60)and normal control group(n=25)by clinicians. The region of interest was evaluated based on the infrared thermal presentation. The highest,lowest and average body surface temperatures over the oropharyneal region were analyzed for quantitative comparison. Results The infrared presentation in the normal group was large green?cool or blue?cold region. However,there were significantly abnormal presentation of infrared thermal images on the body surface corresponding to the oropharyneal region in the tonsillitis group and the laryngopharyngitis group. The infrared thermal distributions in these two groups were similar ,showing patchy ,strip?like diffuse/focal pink?hot or red?heat zones corresponding to oropharyneal region. The highest ,lowest and average body temperatures of lower mandibular region and pharyngeal region in the acute tonsillitis group and the acute laryngopharyngitis group were all higher than those in the normal control group(all P<0.05). However,there were no statistically significant differences between the acute tonsillitis group and the acute laryngopharyngitis group (P>0.05). Conclusion Acute tonsillitis and laryngopharyngitis can show significantly abnormal infrared thermal presentation on the body surface over the corresponding affected region. Compared with normal status,infrared thermal imaging is highly sensitive for detection of acute laryngopharyngitis .
