Abstract：
UNASSIGNED: Infrared thermography (IT) is a non-invasive real-time imaging technique with potential application in different areas of neurosurgery. Despite technological advances in the field, intraoperative IT (IIT) has been an underestimated tool with scarce reports on its usefulness during intracranial tumor resection. We aimed to evaluate the usefulness of high-resolution IIT with static and dynamic thermographic maps for transdural lesion localization, and diagnosis, to assess the extent of resection, and the occurrence of perioperative acute ischemia.
UNASSIGNED: In a prospective study, 15 patients affected by intracranial tumors (six gliomas, four meningiomas, and five brain metastases) were examined with a high-resolution thermographic camera after craniotomy, after dural opening, and at the end of tumor resection.
UNASSIGNED: Tumors were transdurally located with 93.3% sensitivity and 100% specificity (p < 0.00001), as well as cortical arteries and veins. Gliomas were consistently hypothermic, while metastases and meningiomas exhibited highly variable thermographic maps on static (p = 0.055) and dynamic (p = 0.015) imaging. Residual tumors revealed non-specific static but characteristic dynamic thermographic maps. Ischemic injuries were significantly hypothermic (p < 0.001).
UNASSIGNED: High-resolution IIT is a non-invasive alternative intraoperative imaging method for lesion localization, diagnosis, assessing the extent of tumor resection, and identifying acute ischemia changes with static and dynamic thermographic maps.

摘要：
■红外热成像（IT）是一种非侵入性的实时成像技术，在神经外科的不同领域具有潜在的应用价值。尽管该领域的技术进步，术中IT（IIT）一直是一个被低估的工具，关于其在颅内肿瘤切除术中的有用性的报道很少。我们旨在通过静态和动态热成像图来评估高分辨率IIT对硬膜病变定位的有用性，和诊断，为了评估切除的程度，围手术期急性缺血的发生。
■在一项前瞻性研究中，15例受颅内肿瘤影响的患者（6例胶质瘤，四个脑膜瘤,和五个脑转移）在开颅手术后用高分辨率热成像相机检查，硬脑膜开放后，在肿瘤切除结束时。
■肿瘤经dural定位，敏感性为93.3％，特异性为100％（p<0.00001），以及皮质动脉和静脉.胶质瘤始终是低体温的，而转移瘤和脑膜瘤在静态（p=0.055）和动态（p=0.015）成像上表现出高度可变的热像图。残余肿瘤显示非特异性静态但特征性动态热像图。缺血性损伤显著低温(p<0.001)。
■高分辨率IIT是一种用于病变定位的无创替代术中成像方法，诊断,评估肿瘤切除的程度，用静态和动态热像图识别急性缺血的变化。
