Using medical microwave radiometry for brain temperature measurements

Oleg Shevelev et al.

Summary: Brain temperature (BT) is a crucial physiological parameter that can be monitored non-invasively using passive microwave radiometry (MWR) and has important implications for brain diagnostics and physical performance.

An ultrasound negative for subclinical synovitis in arthralgia patients: is it helpful in identifying those not developing arthritis? A longitudinal study in four arthralgia cohorts

Cleo Rogier et al.

Summary: Musculoskeletal ultrasound has a high negative predictive value for inflammatory arthritis in arthralgia patients, primarily due to the already low risk of developing inflammatory arthritis. The additional value of a negative ultrasound result is limited.

Treatment and Companion Diagnostics of Lower Back Pain Using Self-Controlled Energo-Neuroadaptive Regulator (SCENAR) and Passive Microwave Radiometry (MWR)

Alexander Viktorovich Tarakanov et al.

Summary: This study evaluated the effectiveness of various treatment methods for acute and subacute nonspecific lower back pain using passive microwave radiometry. The addition of self-controlled energy-neuroadaptive regulation therapy significantly enhanced the analgesic effect, reducing pain levels by more than double.

Assessment of inflammation in patients with rheumatoid arthritis using thermography and machine learning: a fast and automated technique

Isabel Morales-Ivorra et al.

Summary: In this study, a machine learning-based computational method was used to automatically assess joint inflammation in rheumatoid arthritis (RA) through thermal imaging of the hands. The method, called Thermographic Joint Inflammation Score (ThermoJIS), was trained using data from patients with different types of arthritis and osteoarthritis, and evaluated based on patients with RA. The results showed that ThermoJIS correlated moderately with ultrasound scores and was able to detect joint inflammation even in patients in clinical remission. This opens up an opportunity to develop new tools for routine detection of joint inflammation.

A Core Body Temperature Retrieval Method for Microwave Radiometry When Tissue Permittivity is Unknown

Katrina Tisdale et al.

Summary: This paper presents a novel method for retrieving core temperature using microwave radiometry when the complex permittivity and heat transfer parameters of the tissue layers of the human subject are unknown. The method accounts for population variation in the relevant electromagnetic and thermal parameters, resulting in a retrieval error within the clinically acceptable limit. The results of this study contribute to the advancement of medical microwave radiometry as a clinically viable and accurate noninvasive measurement for all patients.

Development of a Coherent Model for Radiometric Core Body Temperature Sensing

Katrina Tisdale et al.

Summary: This study examines the utility of a physics-based model for determining human core body or brain temperature using microwave radiometry. The results show that the model must incorporate population variation statistics and cover a wide frequency band to accurately retrieve physical temperature. Variation in thermal and electromagnetic parameters affects the emitted brightness temperature profile, and these variations can be analyzed using a Monte Carlo simulation. This study contributes to the development of an on-body radiometer for core temperature measurement across the human population.

Doppler ultrasound predicts successful discontinuation of biological DMARDs in rheumatoid arthritis patients in clinical remission

Lene Terslev et al.

Summary: In RA patients in sustained remission, ultrasound can predict successful discontinuation of bDMARDs based on negative IgM-RF and lower Doppler sum scores. However, the number of previous bDMARDs is a stronger predictor of successful tapering than ultrasound. Clinical parameters do not have predictive value for successful tapering or discontinuation.

Rheumatoid Arthritis Relapse and Remission - Advancing Our Predictive Capability Using Modern Imaging

Lene Terslev et al.

Summary: Subclinical synovitis is linked to structural damage progression and flare risk, indicating clinical composite scores may not fully suppress inflammation; Sustained clinical remission impacts long-term joint damage progression, physical function, and quality of life; Treating subclinical inflammation leads to more frequent strict clinical remission and better physical function, with potential for more adverse events.

Microwave Radiometry (MWR) temperature measurement is related to symptom severity in patients with Low Back Pain (LBP)

A. V. Tarakanov et al.

Summary: The study utilized Microwave Radiometry (MWR) to assess internal tissue temperature in patients with Low Back Pain (LBP), finding a significant increase in deep tissue temperature with pain severity. MWR shows promise for objective measurement of pain severity in patients with LBP.
