PET/CT visualizes extremely rare brain inflammation
By Will Morton
An F-18 FDG-PET/CT scan proved crucial in identifying an ultrarare case of brain inflammation in a patient due to the flu.

Brain MRI and F-18 FDG brain and whole-body PET/CT images. (A) No obvious abnormalities were found in axial and sagittal slices from T2-weighted MR images. (B) Whole cerebellar cortex had diffuse F-18 FDG hypermetabolism in PET/CT brain images, with SUVmax of 25.91. (C and D) Whole-body F-18 FDG-PET/CT showing distended bladder. TLG = total lesion glycolysis; MTV = metabolic tumor volume. Image and caption courtesy of the Journal of Nuclear Medicine.
Thoracic aortic calcification data could help predict CAC risk
By Kate Madden Yee
Adding thoracic aortic calcification data to coronary artery calcification (CAC) models shows promise as a risk prediction biomarker for CAC in asymptomatic patients undergoing chest CT.
March 27, 2025
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.
Nociceptive responses to contrast CT aren't necessarily pathology
By Kate Madden Yee
Nociceptive responses to contrast CT imaging such as intense warmth, urinary urgency, a metallic taste, dry mouth, and mild discomfort or pain aren't necessarily indicators of adverse contrast reactions.

AAPM: CMS measure for reporting CT radiation dose riddled with 'ambiguities'
By Kate Madden Yee
Radiation dose and image quality performance measures for CT imaging accepted by the U.S. Centers for Medicare and Medicaid Services (CMS) in 2023 are "ambiguous" and need to be reconsidered, according to the AAPM.

PSMA PET/CT identifies 'atypical' metastases in prostate cancer patients
By Will Morton
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).
