With experience, readers prefer full-field digital mammo

CHICAGO - Norwegian radiologists found that full-field digital mammography with soft-copy reading is comparable to screen-film while also affording a higher patient throughput. In a presentation at the RSNA meeting on Monday, Dr. Per Skaane discussed his group’s successful results with FFDM, in comparison to screen-film, in a population-based breast cancer screening program at Ulleval University Hospital in Oslo.

Radiation Oncology/Therapy

Radiation must be well targeted to prevent in-stent restenosis

SAN FRANCISCO - Of the 850,000 angioplasties performed in the U.S. this year, a great number of patients will develop recurrent symptoms due to in-stent restenosis. But the clinical outcome analysis from two START trials should help cement the efficacy of radiation therapy in stemming restenosis, according to a presentation at the American Society for Therapeutic Radiology and Oncology meeting.

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.
