Infrared scan of the head in the diagnosis of intracranial pathology

Abstract

The most important task of primary diagnosis in craniocerebral injuries and diseases of the head is to exclude compression of the brain by intracranial hematoma. Modern methods of diagnostics allow to solve this problem with high accuracy, however, the high cost of devices, their stationarity, the need to use high-precision methods of instrumental diagnostics as soon as possible and close to the scene are the main problem at the moment. Here are examined the possibilities, convenience and efficiency of using a portable device for infrared head scanning «Infrared Model 2000 Sensor» in the provision of medical care at advanced stages, in the absence of the necessary technical resources for the verification of intracranial hematoma. The diagnostic value of the method was tested in the clinical departments of the Military medical academy S.M. Kirov. There were 62 patients with various injuries and diseases of the head examined, who was treated at the clinic of neurosurgery and field military surgery from July to August 2017. Echoencephaloscopy was made for all patients in addition to the infrared scanning head. The results were controlled by computed tomography of the head. The age of patients is ranged from 19 to 70 years. In 94% of cases, the infrared head scan was performed during the first day after the manifestation of the disease or injury, with 47% of cases the study was conducted for the first 3 hours, and 7% of cases in the first 3 days after the head injury. The sensitivity of diagnosis of intracranial pathology according to infrared scanning was 72,7%, specificity – 72,5%. False positive results were obtained in 27,3% of cases. The main causes of false positive results were: the presence of subcutaneous hematomas in the study areas, the presence of blood clotting in the scanning area, bleeding from the wounds of the scalp.
