Communal values (i.e., valuing care for and connection with others) are important to individual well-being and societal functioning yet show marked gender differences, with girls valuing communion more than boys do.

Background And Objectives: Vestibular schwannomas demonstrate different responses after stereotactic radiosurgery (SRS), commonly including a transient loss of internal enhancement on postcontrast T1-weighted MRI thought to be due to an early reduction in tumor vascularity. We used dynamic contrast-enhanced based golden-angle radial sparse parallel (GRASP) MRI to characterize the vascular permeability changes underlying this phenomenon, with correlations to long-term tumor regression.

Methods: Consecutive patients with vestibular schwannoma who underwent SRS between 2017 and 2019, had a transient loss of enhancement after SRS, and had long-term longitudinal GRASP studies (6, 18, and 30 months) were included in this retrospective cohort analysis (n = 19).

Achondroplasia is the most common skeletal dysplasia. With the development of new growth-promoting drug treatment for children and adolescents with achondroplasia, multidisciplinary care has become increasingly more important. In addition to orthopedic care, a specialized team comprised of pediatrics/endocrinology, radiology, neurosurgery, otorhinolaryngology, anesthesiology, physiotherapy, psychology and other disciplines is necessary to develop and implement a holistic concept to improve the quality of life for individuals affected by achondroplasia.

Article Synopsis
  • A new approach for real-time volumetric dynamic MRI of the wrist joint is introduced, aimed at improving the evaluation of wrist instability by tracking carpal bone motion during active movement.
  • The study utilized a specialized wrist coil and 3D-printed support platform to capture high-quality 2D images, which were then assembled into dynamic 3D volumes for analysis.
  • Results showed that the method provided high signal-to-noise ratio and accurate visualization of carpal bones, paving the way for advanced segmentation and quantitative assessment of wrist kinematics.
