FES-PET effective for staging breast cancer in phase II trial
By Will Morton
F-18 fluroestradiol (FES)-PET/CT appears as effective as standard imaging for staging women with estrogen receptor-positive locally advanced breast cancer or evaluating suspected recurrence.
July 26, 2024
The patient was a woman in her 50s with suspected recurrence of invasive lobular breast cancer. A, maximum intensity projection image from FDG-PET/CT demonstrating avid foci in the chest (red arrow). Transaxial CT (B) and transaxial fused FDG-PET/CT image (C) showing that the chest avidity corresponds to FDG-avid lung nodules (red arrows) suspicious for malignancy. The lung nodule was subsequently biopsied but found to represent benign granulomatous inflammation and thus a false positive on FDG-PET/CT. D, maximum intensity projection image from FES-PET/CT demonstrating multifocal uptake suspicious for malignancy. E, transaxial CT and fused FES-PET/CT demonstrating no FES-avidity in the biopsy proven benign granulomatous lung nodules (red arrows), thus true negative on FES-PET/CT. FES-avidity in nodes (white arrow) is suspicious for malignancy. F, transaxial CT and fused FES-PET/CT demonstrates gastric avidity (blue arrow) suspicious for malignancy. G, transaxial CT and fused FES PET/CT demonstrates FES-avid osseous foci (yellow arrow) suspicious for malignancy. This osseous focus was subsequently biopsied and proved to be an osseous metastasis and thus true positive on FES-PET/CT.

PET/MRI rules out tau protein in late-life depression
By Will Morton
A PET/MRI study has provided insights into the neurobiology of late-life depression, finding tau protein is not involved in the condition.
July 25, 2024
Coronal and axial slice of the average cortical F-18 MK-6240 SUVR [standard uptake value ratio] image for each study population. SUVR images were corrected for partial volume effects and masked with the gray matter mask used for volume of interest delineation. Overall tau accumulation is comparable between the late-life depression (LLD, middle column) and non-depressed cognitively unimpaired comparison (HC, left column) groups, while abnormal tau accumulation, which is most pronounced in the mesial temporal lobe, can be seen in the mild cognitive impairment due to Alzheimer's disease group (right column).

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.
