We present a case in which attenuation imaging (ATI), a recently developed ultrasonographic application, facilitated the diagnosis of preplacental and postplacental haematoma. Placental abruption is a serious condition that affects the prognosis of infants and is difficult to diagnose. Ultrasonography is the primary imaging modality that complements the clinical findings in the diagnosis; however, its sensitivity is low, and improved diagnostic accuracy is desired. Here, we found that placental haematomas on the placental fetal surface observed at 19 weeks of gestation were indistinct from placental parenchyma in B-mode ultrasonographic imaging. In ATI, the placental parenchyma was colour-mapped, but the haematoma portion was not, which helped identify the haematoma. ATI, which also colour-maps uniform tissues, did not colour-map vessels within the placenta. ATI has a breakthrough potential for improving the diagnosis of placental abruption.

Microplastics (MPs), defined as plastic particles smaller than 5 mm, have garnered considerable attention owing to their potential biological impact on human health. These particles exhibit a range of physicochemical properties, including size, shape, and surface oxidation. Nile Red is a prominent tool for detecting microplastics, enabling staining for dynamic analyses within biological systems.

There is currently no cure or disease-modifying treatment for post-traumatic osteoarthritis (PTOA). This study aims to assess the efficacy of dimethyl fumarate (DMF), a US-FDA approved drug for multiple sclerosis, as a treatment for PTOA. PTOA was induced in male Lewis rats by medial meniscal transection (MMT) surgery, and DMF was intra-articularly administered once, one week following surgery.

Background And Objectives: Lung cancer screening is critical for early detection and management, particularly through the use of computed tomography (CT). This study aims to compare the Lung Imaging Reporting and Data System (Lung-RADS) Version 2022 with the British Thoracic Society (BTS) guidelines in classifying solid pulmonary nodules detected at lung cancer screening CT examinations.
Materials And Methods: This retrospective study included 224 patients who underwent lung cancer screening CT between 2016 and 2022 and had a reported solid pulmonary nodule.
Research on Dry Coupling Technology in the Ultrasonic Non-Destructive Testing of Concrete.

In the health monitoring and safety assessments of concrete structures, ultrasonic non-destructive testing (NDT) technology has become an indispensable tool due to its non-destructive nature, efficiency, and precision. However, when used in inspecting irregular concrete surfaces, traditional planar ultrasonic transducers often encounter energy loss and signal attenuation induced by poor interface coupling, which significantly reduces the accuracy and reliability of the test results. To address this problem, this article proposes a point-contact dry coupling ultrasonic transducer solution, which enables efficient acquisition of ultrasonic signals within concrete without the need for couplants.

Background/objectives: This study aimed to investigate whether post-operative changes in the computed tomography (CT)-attenuation of subcutaneous (SAT) and visceral (VAT) adipose tissues were significantly associated with recurrence-free survival (RFS), peritoneal RFS, and overall survival (OS) in patients with stage II-III gastric cancer.
Methods: This retrospective study analyzed 243 patients with stage II-III gastric cancer who underwent curative surgery. CT-attenuation values of SAT (SAT HU) and VAT (VAT HU) were measured from non-contrast-enhanced abdominopelvic CT images taken pre-operatively and 6 months post-operatively.
