Images of a 39-year-old who underwent screening mammography. Right craniocaudal (left) and mediolateral oblique (middle) views from preoperative mammography show suspicious grouped fine pleomorphic calcifications (arrows). After biopsy showed ductal carcinoma of situ (DCIS), patient underwent breast-conserving surgery, yielding final diagnosis of ductal carcinoma in situ (intermediate grade, hormone receptor positive). (Right) Screenshot of an output of a commercial AI tool applied to preoperative mammography. AI detected right breast lesion with score of 95% on both views (concentric colored circles). Present study’s reviewing radiologist deemed AI marking to correspond with site of DCIS.

Axial contrast-enhanced CT scan in a 28-year-old premenopausal woman shows an incidentally detected solid-appearing left ovarian lesion (solid arrow) anterior to the uterus (U), associated with trace ascites in the right adnexa and cul de sac (dashed arrows). At pathologic analysis, this was shown to be ovarian dysgerminoma. Two readers misdiagnosed this lesion, one as a leiomyoma and one as an ovarian fibroma.

MRI model predicts treatment response in breast cancer patients
By Amerigo Allegretto
Radiomics scoring derived from contrast-enhanced MRI can predict treatment response in women being treated for triple-negative breast cancer.
September 3, 2024
Axial dynamic contrast-enhanced MRI scans show results from two women before they underwent neoadjuvant chemoimmunotherapy for triple-negative breast cancer. (A) T1-enhanced MRI scan, (B) rate constant for contrast agent plasma-to-interstitial transfer (Ktrans) map, and (C) maximum contrast agent uptake rate (Slopemax) map in a 56-year-old woman depict a tumor that manifested as a spherical 4-cm mass enhancement (arrow in A) in the right breast with axillary node involvement (arrowhead in A). The radiomics score was high, at 3.3. Histopathologic examination after chemotherapy revealed no invasive residual cancer in the breast or the lymph nodes (pathologic complete response). (D) T1-enhanced MRI scan, (E) Ktrans map, and (F) Slopemax map in a 49-year-old woman show a tumor that manifested as a spiculated 3-cm mass enhancement (arrow in D) in the left breast with thickening of the skin (arrowhead in D). The parametric maps show much greater spatial heterogeneity than in the case shown in B and C, with areas of high intensity. The radiomics score was low, at −1.6. Histopathologic examination after chemotherapy revealed a 10-mm invasive residual cancer in the breast (not pathologic complete response). Image courtesy of the RSNA.

PET reveals brain pathology that may drive depression
By Will Morton
Early brain accumulation of amyloid plaque on PET scans is associated with emerging depressive symptoms in cognitively unimpaired older adults.
August 29, 2024
Pittsburgh Compound B (PiB) PET distribution volume ratio (DVR) images were projected onto fsaverage surfaces from FreeSurfer and surface smoothed, with PiB (amyloid) slope maps created using ordinary least squares regression (time as only factor) and mixed effects models for 154 participants run at each vertex (P < .01; model: longitudinal Geriatric Depression Scale score estimated by amyloid slope × time + [sex + education + age] × time). This map visualizes the results of the linear mixed-effects models (t score of the main variable, amyloid slope × time) such that regions with a greater t score (red) represent areas in which greater depressive symptoms are associated with greater amyloid accumulation (amyloid slope). Anatomical landmarks are provided: L refers to the left hemisphere, R refers to the right hemisphere, and additional labels indicate the anterior and posterior ends of the brain.
