Simultaneous Bilateral T, T, and T Relaxation Mapping of Hip Joint With 3D-MRI Fingerprinting.

Background: Three-dimensional MR fingerprinting (3D-MRF) has been increasingly used to assess cartilage degeneration, particularly in the knee joint, by looking into multiple relaxation parameters. A comparable 3D-MRF approach can be adapted to assess cartilage degeneration for the hip joint, with changes to accommodate specific challenges of hip joint imaging.

Purpose: To demonstrate the feasibility and repeatability of 3D-MRF in the bilateral hip jointly we map proton density (PD), T, T, T, and ∆B in clinically feasible scan times.

Optimized MR pulse sequence for high-resolution brain 3D-T1ρ mapping with weighted spin-lock acquisitions.

Purpose: To implement and evaluate the feasibility of brain spin-lattice relaxation in the rotating frame (T1ρ) mapping using a novel optimized pulse sequence that incorporates weighted spin-lock acquisitions, enabling high-resolution three-dimensional (3D) mapping.

Methods: The optimized variable flip-angle framework, previously proposed for knee T1ρ mapping, was enhanced by integrating weighted spin-lock acquisitions. This strategic combination significantly boosts signal-to-noise ratio (SNR) while reducing data acquisition time, facilitating high-resolution 3D-T1ρ mapping of the brain.

Mental health and justice beyond borders: Global crises, sociopolitical determinants, and contemporary practices in forensic psychiatry.

In an era marked by escalating international crises, environmental shifts, and sociopolitical volatilities, global mental health is facing profound challenges. With its distinctive position at the intersection between clinical and judicial domains, forensic psychiatry can be predisposed to the consequences of adverse external determinants and events. At present, geopolitical conflicts, rising insecurities, climate change, forced and voluntary migration, and regressive sociopolitical ideologies are all compounding role responsibilities, care models, and ethical expectations across forensic-psychiatric practice; in short, complex distal factors are increasingly informing domestic considerations.

Geopolitical determinants of mental health and global health inequities.

Geopolitical determinants of health have been well recognized by the World Health Organization and are increasingly being discussed across governments, institutions, academics, policy makers, and across global health sector. Geopolitical determinants of health are events, structures, processes, and factors that influence individual health including mental health, public and population mental health both directly and indirectly. Consequently, nation's responses to these factors will affect short-term and long-term health outcomes.
