Tau PET identifies grey matter atrophy in retired athletes
By Will Morton
Flortaucipir PET imaging is able to identify neuropathological brain changes in retired contact sport athletes at risk of neurodegeneration.
July 24, 2024
Example of the flortaucipir tau-PET signal and distribution of low grey matter volume in a single former athlete. Spatial maps of the flortaucipir tau-PET standardized update value (SUVR) (top) and the reduced grey matter volumes showed in blue and defined as voxels with a w-score of >1.5 below the mean (bottom) in a single former athlete.

Mammo AI falls short to ultrasound in screening dense breasts
By Amerigo Allegretto
Mammography plus ultrasound yields better results than AI-enhanced mammography alone when it comes to screening of women with dense breasts.
July 23, 2024
Imaging in a 56-year-old woman with heterogeneously dense breasts (BIRADS C). (A) Left craniocaudal (left) and mediolateral oblique (right) digital mammograms show no abnormality. (B) Left craniocaudal (LCC, top) and left mediolateral oblique (LMLO, bottom) mammograms with retrospectively applied AI (Lunit Insight MMG, version 1.1.7.1; Lunit) show the lesion was given abnormality scores of 97% and 71%, respectively. The color bar indicates pixel-level abnormality scores corresponding to heatmap contour lines. Breast ultrasound performed the same day was considered negative (not shown). (C) Left craniocaudal (left) and mediolateral oblique (right) digital mammograms acquired nine months later show an irregular mass (arrows) in the left breast, which correlates with the heatmap areas scored as 97% and 71% by AI in the earlier screening mammogram (B). The radiopaque round marker denotes the site of the palpable abnormality indicated by the patient. (D) Transverse ultrasound imaging shows an irregular mass (arrow) in the left breast. The patient was treated with breast-conserving surgery, and the mass was proven to be invasive lobular carcinoma. Image courtesy of the RSNA.
