Special Issue Information

Dear Colleagues,

This Special Issue aims to collect original scientific articles and reviews on the latest developments regarding the use of "Point-of-care" ultrasound imaging. “Point-of-care” ultrasound is defined as “a form of examination using imaging ultrasound (…) to clarify ambiguities arising during a physical/functional examination and to ensure the appropriate quality and effectiveness of therapy”. In recent years, there has been increasing interest in this form of ultrasound imaging diagnostics among various medical professionals. This is particularly visible in physiotherapy, emergency medical services, but also in other medical professions. "Point-of-care" ultrasound can be used not only to confirm a functional diagnosis, but also in other ways: "Point-of-care" diagnostic ultrasound imaging, as an aid in the functional diagnosis of neuromusculoskeletal and others disorders; "Point-of-care"  therapeutic ultrasound imaging (as sonofeedback-supporting therapeutic procedures); "Point-of-care" interventional ultrasound imaging (as a support for percutaneous procedures, vascular procedures, intramuscular procedures, intra-articular procedures, dry needling, acupuncture, percutaneous electrolysis, etc.); and "Point-of-care" scientific ultrasound imaging (as a research tool for the objective assessment of the structure and function of muscles and other tissues as well as the effects of therapy used in scientific research). Scientific evidence in the literature supports the growing interest and benefits of using "Point-of-care" ultrasound imging in various medical professions. Future research should aim to expand the application areas of "Point-of-care" ultrasound imaging and demonstrate its applicability in other diseases, the usefulness of which has not yet been assessed.

Infant meningitis remains a severe burden on global health, particularly for young infants. Traditional ultrasound imaging techniques are limited in spatial resolution to visualize white blood cells (WBCs) in the cerebrospinal fluid (CSF), which is considered a well-established marker for meningitis detection. This work presents a novel platform that uses high-resolution ultrasound to detect the backscatter signals from microscopic CSF WBCs through the anterior fontanelle of neonates and young infants. The whole system was built around a custom probe that allows for a 20 MHz focused transducer to be mechanically controlled to map the area of interest in the CSF. Data processing can be performed internally in the device without the need to extract the images for further analysis. The in vitro feasibility of the proposed solution was evaluated in imaging 7 μm particle suspensions at different concentrations relevant to meningitis diagnosis ranging from 7- to 646-particles (pp)/μL. The experimental tests were conducted from a simple setup using a sample container to a more realistic setup based on an anatomical phantom of the neonatal head. The results show high-quality images, where 7 μm particles can be resolved for the different concentrations. Full article

Ultrasound imaging (US) is being increasingly used to aid in the diagnosis of entrapment neuropathies. This study aims to evaluate the shear modulus and cross-sectional area (CSA) of the median nerve in patients with carpal tunnel syndrome (CTS). A total of 35 patients with CTS participated in the study. CSA and shear modulus testing were performed in shear wave elastography (SWE) mode in five positions of the right and left radiocarpal joints (intermediate position 0°, 45° of extension, maximum extension, 45° of flexion, and maximum flexion). There were significant side-to-side differences in the median nerve shear modulus at each wrist position as compared to the asymptomatic side. There were significant side-to-side differences in the median nerve CSA at each wrist position as compared to the asymptomatic side. Shear modulus increases in patients with CTS at different angular positions of flexion and extension of the radiocarpal joint. In individuals with CTS, the CSA of the median nerve is greater on the symptomatic side compared to the asymptomatic side. The CSA decreases in positions of maximum extension and 45° of flexion and in maximum flexion relative to the resting position. Full article

This study investigated the reliability of measuring the median nerve cross-sectional area (CSA) at the carpal tunnel inlet using a handheld ultrasound device (HUD) compared to a standard ultrasound system, focusing on intra- and inter-operator reproducibility among novice and expert operators. Employing a prospective cross-sectional design, 37 asymptomatic adults were assessed using both devices, with measurements taken by an expert with over five years of experience and a novice with less than six months. The CSA was determined using manual tracing and ellipse methods, with reproducibility evaluated through intraclass correlation coefficients (ICCs) and agreement assessed via Bland–Altman plots. Results showed a high degree of agreement between the devices, with excellent intra-operator reproducibility (ICC > 0.80) for the expert, and moderate reproducibility for the novice (ICCs ranging from 0.539 to 0.841). Inter-operator reliability was generally moderate, indicating acceptable consistency across different experience levels. The study concludes that HUDs are comparable to standard ultrasound systems for assessing median nerve CSA in asymptomatic subjects, with both devices providing reliable measurements. This supports the use of HUDs in diverse clinical environments, particularly where access to traditional ultrasound is limited. Further research with a larger sample and symptomatic patients is recommended to validate these findings. Full article
