Third trimester fetal 4D flow MRI with motion correction.
Magn Reson Med
January 2025
Department of Radiology & Nuclear Medicine, Amsterdam University Medical Center, University of Amsterdam, Amsterdam, The Netherlands.
Purpose: To correct maternal breathing and fetal bulk motion during fetal 4D flow MRI.
Methods: A Doppler-ultrasound fetal cardiac-gated free-running 4D flow acquisition was corrected post hoc for maternal respiratory and fetal bulk motion in separate automated steps, with optional manual intervention to assess and limit fetal motion artifacts. Compressed-sensing reconstruction with a data outlier rejection algorithm was adapted from previous work.
Prediction of post-contrast acute kidney injury by bedside ultrasonography.
BMC Emerg Med
January 2025
Department of Emergency Medicine, Recep Tayyip Erdoğan University Training and Research Hospital, Rize, 53020, Turkey.
Background: The incidence of contrast-induced acute kidney injury (CI-AKI) in the general population ranges from 0.6 to 2.3%, whereas for specific high-risk patients, the incidence can reach more than 30-40%.

Department of Emergency Medicine, Assistance publique des hôpitaux de Marseille (APHM), Marseille University, Timone University Hospital, Marseille, France.
Background: The early mortality of trauma patients, mainly from hemorrhagic shock, raises interest in detecting the presence of non-exteriorized bleeding. Intra-hospital EFAST (Extended Focused Assessment with Sonography for Trauma) has demonstrated its utility in the assessment and management of severe trauma patients (STP). However, there is a lack of data regarding the diagnostic performance of prehospital EFAST (pEFAST).

Chest
January 2025
Department of Medicine, University of British Columbia. Electronic address:
Topic Importance: Accurate assessment of a patient's volume status is crucial in many conditions, informing decisions on fluid prescribing, vasoactive agents, and decongestive therapies. Determining a patient's volume status is challenging, due to limitations in examination and investigations and the complexities of fluid homeostasis in disease states. Point-of-care ultrasound (POCUS) is useful in assessing hemodynamic parameters related to volume status, fluid responsiveness, and fluid tolerance.

The COVID-19 pandemic has highlighted the critical need for pathogen detection methods that offer both low detection limits and rapid results. Despite advancements in simplifying and enhancing nucleic acid amplification techniques, immunochemical methods remain the preferred methods for mass testing. These methods eliminate the need for specialized laboratories and highly skilled personnel, making home testing feasible.
