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.

In targeted alpha-particle therapy, actinium-225 (Ac-225) has emerged as a radionuclide of potential, driving extensive efforts to develop innovative radiopharmaceuticals. High-resolution imaging of alpha particles is required for precisely detecting alpha-emitting radionuclides in cellular environments and small organs. Here, we report real-time trajectory imaging of alpha particles emitted by Ac-225 and its daughter radionuclides, utilizing an alpha particle trajectory imaging system.

Department of Nuclear Medicine, Zhejiang Cancer Hospital, Hangzhou, 310022, Zhejiang, China.
This study aimed to establish and validate prognostic nomogram models for patients who underwent I therapy for thyroid cancer with distant metastases. The cohort was divided into training (70%) and validation (30%) sets for nomogram development. Univariate and multivariate Cox regression analyses were used to identify independent predictors for overall survival (OS) and progression-free survival (PFS).

Photoelectrochemical (PEC) immunosensors are highly promising tools for monitoring biochemical molecules. Constructing high-performance heterojunctions is a general method to improve the sensitivity of PEC immunosensors. The internal electric field (IEF) formed at the heterojunction interface plays a crucial role in coordinating the separation of photogenerated carriers.

However, only a few dried foods have a specified weight change rate. Accurate specific weight change rates are critical in determining the compliance of a dried food item with Japanese maximum limits (JMLs) for radioactivity.
