Background: Metal structures are a source of artifacts that significantly complicate the interpretation of magnetic resonance imaging (MRI). The use of prostate MRI as a preliminary test in men with a suspicion on prostate cancer leads to an increased use of the test. The aim of this study was to solve a clinically significant problem: to ensure the reduction of artifacts from metal hip implants during prostate MRI.

- Researchers are studying the multi-scale interstellar medium (ISM) of our Galaxy to understand the relationships between gas, dust, and star formation in Giant Molecular Clouds (GMCs).
- The Milky Way's complex structure is influenced by massive stars and dust lanes, making it essential to observe these features at (sub-)millimeter wavelengths for in-depth analysis.
- A proposed 50m single-dish sub-mm telescope called AtLAST aims to provide comprehensive observations of the Galactic Plane and surrounding areas to enhance our understanding of stellar formation, planetary system evolution, and the overall ecology of our Galaxy.
Background/objectives: While multiple studies have investigated antibiotic consumption rates, there are few studies on the consumption of systemic antifungals and antiprotozoals. This study aims to fill this gap by providing a comprehensive analysis of nationwide consumption trends in Kazakhstan over a seven-year period (2017-2023).
Methods: Defined daily doses per 1000 inhabitants per day were calculated for systemic antifungals (J02 code of the Anatomical Therapeutic Chemical Classification System (ATC)) and antiprotozoals (P01 code of the ATC).
Background: Anthropomorphic phantoms play an important role in routine clinical practice. They can be used to calibrate magnetic resonance imaging (MRI) scanners, control the diagnostic equipment quality, and reduce the acquisition time. The latter is especially critical for diagnosing fetal anomalies, which requires optimal image quality within the shortest possible time.

Background: Stereotactic radiosurgery (SRS) for cerebral cavernous malformations has been used for more than 30 years. However, indications for this method and outcomes are still discussable.
Objective: To analyze available literature data on SRS for cerebral cavernous malformations with assessment of indications for treatment, radiation parameters, radiological and clinical complications and outcomes.
