Which PSMA PET/CT interpretation criteria most effectively diagnose prostate cancer? a retrospective cohort study.
BMC Med Imaging
January 2025
Department of Urology, The First Hospital of Shanxi Medical University, Taiyuan, 030000, China.
Background: PSMA PET/CT emerges as a pivotal technology in the diagnostic landscape of prostate cancer (PCa). It offers a suite of imaging interpretation criteria, notably the maximum standardized uptake value (SUVmax), the molecular imaging prostate-specific membrane antigen score (miPSMA score), and the PSMA reporting and data system (PSMA-RADS). Identifying the most valuable criteria for diagnosing PCa and standardizing imaging interpretation across various tracers is an unresolved question.

Accurate rupture risk assessment is essential for optimizing treatment decisions in patients with cerebral aneurysms. While computational fluid dynamics (CFD) has provided critical insights into aneurysmal hemodynamics, most analyses focus on blood flow patterns, neglecting the biomechanical properties of the aneurysm wall. To address this limitation, we applied Fluid-Structure Interaction (FSI) analysis, an integrative approach that simulates the dynamic interplay between hemodynamics and wall mechanics, offering a more comprehensive risk assessment.

Epilepsy, a neurological disorder characterized by recurrent unprovoked seizures, significantly impacts patient quality of life. Current classification methods focus primarily on clinical observations and electroencephalography (EEG) analysis, often overlooking the underlying dynamics driving seizures. This study uses surface EEG data to identify seizure transitions using a dynamical systems-based framework-the taxonomy of seizure dynamotypes-previously examined only in invasive data.

The selective Au deposition at the Au-substrate interface is known to give ultrathin Au nanowires and the synthesis usually employs strong thiol-based ligands. It is shown that, by increasing the rate of Au deposition, weak cetyltrimethylammonium bromide (CTAB) can be made to behave like a strong ligand, so that it induces Active Surface Growth and gives Au nanowires. The ligand strength also depends on the packing interactions in the ligand layer, in the order of CTAB, CTAB, and CTAB.

Department of Cardiothoracic Surgery, Erasmus University Medical Center, Rotterdam, The Netherlands.
Purpose: In this feasibility study, we aimed to create a dedicated pulmonary augmented reality (AR) workflow to enable a semi-automated intraoperative overlay of the pulmonary anatomy during video-assisted thoracoscopic surgery (VATS) or robot-assisted thoracoscopic surgery (RATS).
Methods: Initially, the stereoscopic cameras were calibrated to obtain the intrinsic camera parameters. Intraoperatively, stereoscopic images were recorded and a 3D point cloud was generated from these images.
