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.

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.

J Cancer Res Clin Oncol
January 2025
Department of Medical Oncology, Cancer Center, West China Hospital, Sichuan University, 37 Guoxue Alley, Chengdu, Sichuan, 610041, China.
Purpose: To evaluate the added value of additional Ga-FAPI PET/CT following CT for primary staging, detection of postoperative recurrence, and management of gastric cancer patients.
Methods: We retrospectively included patients with gastric cancers who underwent contrast-enhanced computed tomography (ceCT), followed by Ga-FAPI PET/CT within 30 days. Ga-FAPI PET/CT was performed for initial staging or detection of postoperative recurrence.
F-Prostate-Specific Membrane Antigen PET/CT imaging for potentially resectable pancreatic cancer (PANSCAN-2): a phase I/II study.
Cancer Imaging
January 2025
Department of Surgery, Amsterdam UMC Location Vrije Universiteit Amsterdam, De Boelelaan 1117, Amsterdam, the Netherlands.
Background: Current diagnostic imaging modalities have limited ability to differentiate between malignant and benign pancreaticobiliary disease, and lack accuracy in detecting lymph node metastases. F-Prostate-Specific Membrane Antigen (PSMA) PET/CT is an imaging modality used for staging of prostate cancer, but has incidentally also identified PSMA-avid pancreatic lesions, histologically characterized as pancreatic ductal adenocarcinoma (PDAC). This phase I/II study aimed to assess the feasibility of F-PSMA PET/CT to detect PDAC.

Open Heart
January 2025
Department of Cardiology, University Hospital Basel, Basel, Switzerland.
Background: The majority of functional ischemia tests in patients with suspected chronic coronary syndromes (CCS) yield normal results. Implementing gatekeepers for patient preselection, such as pretest probability (PTP) and/or coronary artery calcium score (CACS), could reduce the number of normal scan results, radiation exposure and costs. However, the efficacy and safety of these approaches remain unclear.
