AI improves x-ray reads for rads with varying experience
By Will Morton
AI assistance can improve the detection accuracy of thoracic abnormalities on chest x-rays across radiologists with varying levels of expertise.
December 13, 2023
AI detected a lung mass, a lung nodule, and a small pneumothorax. Without AI assistance, only one thoracic radiologist and one general radiologist detected all abnormalities, whereas with AI assistance, one thoracic radiologist, two general radiologists, and one resident detected all abnormalities. Corresponding coronal and axial CT images show the lung mass (arrows), the lung nodule (white arrowheads), and the small pneumothorax (black arrowheads) that should have been detected on the chest radiograph.

DBT plus mammo detects breast cancers with higher histologic grades
By Amerigo Allegretto
Digital breast tomosynthesis (DBT) plus synthesized mammography screening leads to higher detection of early-stage invasive breast cancers grades 2 or 3.

Imaging depicts a screen-detected invasive breast cancer in the dense breast tissue of a 59-year-old woman. A section in the mediolateral oblique view from a DBT exam of the left breast shows an irregular mass with surrounding architectural distortion (circle). The participant had no history of breast cancer and had been screened previously in the German mammography screening program. Histologic analysis showed invasive carcinoma of no special type, grade 2, with tumor size of 18 mm. Image courtesy of the RSNA.
