“…It turned out to be applicable to assessing the internal temperature of the brain. Measurement accuracy by MWR is ±0.23 °C, which is similar to the results obtained when measuring temperature with sensors implanted to a depth of 3–4 cm in the brain parenchyma [ 28 ].…”

The study of circadian rhythms in the human body using temperature measurements is the most informative way to assess the viability of the body’s rhythm-organizing systems. Pathological processes can affect circadian rhythm dynamics in damaged organs. Severe brain damage that caused the development of disorders of consciousness (DOC) (strokes, traumatic brain injury) disrupts the activity of central oscillators, by directly damaging or destroying the periphery links, and the level of preservation of circadian rhythms and the dynamics of their recovery can be informative diagnostic criteria for patient’s condition assessment. This study examined 23 patients with DOC by using a non-invasive method for obtaining body and cerebral cortex temperature to compare with healthy controls. Measurements were made with a 4 h interval for 52 h beginning at 08:00 on day 1 and ending at 08:00 on day 3. The profile of patients with DOC showed complete disruption compared to healthy controls with rhythmic patterns. The results indicate that the mechanisms for maintaining brain circadian rhythms are different from general homeostasis regulation of the body. Use of microwave radio thermometry for the identification of rehabilitation potential in patients with DOC is a promising area of investigation.

Modern humanity wades daily through various radiations, resulting in frequent exposure and causing potentially important biological effects. Among them, the brain is the organ most sensitive to electromagnetic radiation (EMR) exposure. Despite numerous correlated studies, critical unknowns surround the different parameters used, including operational frequency, power density (i.e., energy dose), and irradiation time that could permit reproducibility and comparability between analyses. Furthermore, the interactions of EMR with biological systems and its precise mechanisms remain poorly characterized. In this review, recent approaches examining the effects of microwave radiations on the brain, specifically learning and memory capabilities, as well as the mechanisms of brain dysfunction with exposure as reported in the literature, are analyzed and interpreted to provide prospective views for future research directed at this important and novel medical technology for developing preventive and therapeutic strategies on brain degeneration caused by microwave radiation. Additionally, the interactions of microwaves with biological systems and possible mechanisms are presented in this review. Treatment with natural products and safe techniques to reduce harm to organs have become essential components of daily life, and some promising techniques to treat cancers and their radioprotective effects are summarized as well. This review can serve as a platform for researchers to understand the mechanism and interactions of microwave radiation with biological systems, the present scenario, and prospects for future studies on the effect of microwaves on the brain.

“…First, the temperature fields of symmetrical zones are determined, which makes it possible to reveal the temperature asymmetry and determine the side of the anomaly. It is desirable to highlight the maximum and minimum temperatures and their difference, which increase or decrease depending on the pathology, as in the brain [53] or venous diseases [54]. With the simultaneous measurement of MWR and IR temperatures in case of a disease, the correlations between them decrease.…”

Passive Microwave Radiometry as a Component of Imaging Diagnostics in Juvenile Idiopathic Arthritis

Juvenile idiopathic arthritis (JIA) is a disease with unknown causes in all forms of arthritis in children under 16 years of age. It is diagnosed when other joint pathologies are excluded. Difficulties in early and differential diagnoses lead to rapid disability and an unfavorable life prognosis. Therefore, a timely diagnosis is necessary to prevent irreversible damage to joints and preserve their function. Due to the widespread use of new technologies, modern multimodal imaging has gained recognition, including radiography, ultrasound, and MRI. The combination of methods plays a key role in confirming the diagnosis, monitoring the disease activity, the prognosis during the disease course, and the outcome in children with JIA. Each method has its advantages and disadvantages. The introduction of passive microwave radiometry (MWR), in combination with other imaging methods, makes it possible to expand the possibilities of screening the disease in the preclinical and early clinical phases.
