Digital tomosynthesis beats standard DR in finding chest lesions

Early clinical results with a digital radiography (DR)-based tomosynthesis system indicate that it outperforms conventional digital x-ray in detecting pulmonary nodules. Duke University researchers found that tomosynthesis had triple the sensitivity of standard DR for detecting nodules large enough to require further diagnostic workup.

PACS data-mining tool analyzes CR retake rates

Researchers from Spain have developed software that analyzes PACS data to automatically perform quality control analysis of retake rates of computed radiography studies. They believe their QC tool could make it easier for imaging facilities to reduce retakes and improve the overall quality of service.

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.
