PSMA-PET/CT identifies 'atypical' metastases in prostate cancer patients
PET/CT scans with an experimental PSMA imaging agent can identify supraclavicular nodal metastasis in newly diagnosed prostate cancer patients.
March 21, 2025
F-18 PSMA-1007 PET/CT of a 70 year old with newly diagnosed prostate cancer: PSA 770 ng/ml; Gleason 5 + 5; International Society of Urological Pathology grade 5. The maximum intensity projection images, CT, and fused images show PSMA ligand-avid prostate primary with pelvic, retroperitoneal, and mediastinal nodal spread. Additionally, he had left supraclavicular nodal metastasis (arrows).

PET/CT visualizes extremely rare brain inflammation
Representative examples of visual TAC categories, assessed on chest CT in asymptomatic individuals undergoing general health screening (blue indicates segmented TAC at level of aortic arch). Axial (A) and sagittal volume-rendered (B) images in 42-year-old patient. AI-based quantification yielded TAC volume of 101 mm3 and TAC Agatston score of 105. Examination was assessed as showing visually mild TAC. Axial (C) and sagittal volume-rendered (D) images in 57-year-old patient. AI-based quantification yielded TAC volume of 834 mm3 and TAC Agatston score of 993. Examination was assessed as showing visually moderate TAC. Axial (E) and sagittal volume-rendered (F) images in 65-year-old patient. AI-based quantification yielded TAC volume of 4872 mm3 and TAC Agatston score of 5848. Examination was assessed as showing visually severe TAC. Images and caption courtesy of the AJR.
