“…[ 5 ] Thermographic cameras provide a sensitivity of less than 1 mK. [ 3 ] The use of IT in neurosurgery has been investigated to differentiate between healthy and abnormal brain tissue. Image evaluation shows differences for both types of tissue, as neoplasms and normal tissue have different characteristics that produce and transfer heat.…”

“…[ 5 10 ] Intraoperative IT is becoming a promising new real-time diagnostic method: noninvasive, radiation-free, without exposure to drugs and without any known side effect. It can also improve the accuracy of tumor resections, as well as the assessment of cerebral blood flow in vascular neurosurgery, to prevent the irreversible damage due to ischemia during surgery,[ 3 6 ] among other potential indications.…”

Background:Infrared thermography (IT) is a noninvasive, real-time diagnostic method that requires no contact with the patient and has a broad spectrum of potential applications in neurosurgery. It has been previously demonstrated the high sensitivity and specificity that IT has to detect brain blood flow changes.Case Description:The case is based on a 64-year-old diabetic and hypertensive male, to whom an anterior communicating artery (ACoA) incidental aneurysm was discovered. We performed the basal infrared thermography mapping (ITM) and immediately after the transitory clip placement in both A1 segments of the anterior cerebral artery (A1-ACA), we performed a second ITM of the exposed brain cortex. After the definitive clip placement in the neck of the ACoA aneurysm, we removed the transitory clips of both A1-ACA and performed a third ITM of the cortical surface, without finding any cortical cooling or significative temperature differences (Ϫt) compared to the basal ITM. The postoperatory computed tomography (CT) and angio-CT did not show any ischemic damage and confirmed the accurate aneurysm clipping.Conclusions:The ITM seems to be a real-time, safe, and useful brain mapping method to identify different temperature zones and temperature dispersion gradients in the human brain cortex. More studies are needed to evaluate the potential applications of IT mapping of the human brain and its use in neurosurgery and vascular neurosurgery.

“…Kateb et al (2009) used Intraoperative Thermal Imaging (ITI) in a patient with a metastatic intracortical melanoma and showed that ITI is a novel neuroimaging technique that can potentially locate the margins of primary and metastatic brain tumors. Hollmach et al (2013), Hoffmann et al (2014) and Kastek et al (2014) investigated the applicability and accuracy of the intraoperative thermography in the neurosurgical procedures.…”

“…[3] ITM in neurosurgery has been used with good results to monitor cerebral blood flow after the resection of an arteriovenous malformation, to observe patency of bypass and to prevent irreversible damage due to ischemia during surgery, in temporary occlusion of brain arteries, among other scenarios. [1,5,7,9,10,14,16] Intraoperative IT is becoming a promising new real-time diagnostic method because it is non-invasive, radiation free, avoids exposing the patient to drugs or contrast media and it has no known side effects.…”

Background: Safety and efficacy are irrebuttable goals in neurosurgery. Methods: We performed a subcortical cavernoma resection in an eloquent area, where we recorded and compared the maximal and minimal brain temperature measured by an infrared thermographic camera and thermometer with the neuronavigation (NN) target location and real anatomical lesion location. Results: The hottest cortical point correlated to the subcortical cavernoma location. The NN located the target at 10 mm away from the hottest point. Conclusion: More studies are needed to better understand the thermic radiation of the brain in health and in disease, but we believe that evaluating brain temperature, it could be possible to improve accuracy in neurosurgery and generate more knowledge about brain metabolism in vivo.
