While breast cancer imaging guidelines recommend annual screening for five years after treatment for ductal carcinoma in situ (DCIS), a new study of over 12,000 women found that only 52 percent had consistent surveillance screening with researchers noting disproportionately lower follow-up imaging rates for Black and Hispanic women.

Emerging research suggests that magnetic resonance imaging (MRI) may help downgrade nearly 10 percent of suspected BI-RADS 3 lesions from ultrasound imaging

In a study looking at acute muscle injuries in professional athletes, the use of magnetic resonance imaging (MRI) within a week prior to their return to play demonstrated significant re-injury risk with intermuscular edema, callus gap and transversal and/or mixed connective tissue gap.

Emerging research suggests that a ketogenic diet reduces the uptake of 18F-fluorodeoxyglucose (18F-FDG) in brain positron emission tomography (PET) scans with a more pronounced effect in the precuneus.

In a video interview discussing one of her recent lectures at the Radiological Society for North America (RSNA) conference, Nina Kottler, M.D., M.S., noted how the combination of artificial intelligence (AI) and radiologist experience can help mitigate bias limitations with the development of AI algorithms as well as educational biases inherent to a radiologist’s training and experience.

The artificial intelligence (AI) software Saige-Density™ reportedly provides automated assessment of breast density during mammography exams.

Reportedly the first targeted molecular imaging agent to provide intraoperative illumination of lung cancer, Cytalux (pafolacianine) helped identify clinically significant events in more than 50 percent of patients undergoing surgery for confirmed or suspected pulmonary nodules, according to Phase 3 trial data presented earlier this year at the American Association for Thoracic Surgery Annual Meeting.

In addition to summary sensitivity and specificity of 92 percent and 91 percent respectively for characterization of indeterminate adnexal lesions, the meta-analysis on pelvic magnetic resonance imaging (MRI) revealed higher summary malignancy rates for O-RADS MRI 4 and 5 lesions than predicted.

Employing an artificial intelligence (AI) tool to quantify airway-to-artery (AAR) diameter ratios on chest computed tomography (CT), researchers found the percentage of airways with an AAR greater than 1 was associated with increased pulmonary exacerbations in ever-smokers.

In a study of nearly 18,000 men who had prostate cancer screening, researchers found the use of pre-biopsy magnetic resonance imaging (MRI) for those with elevated prostate-specific antigen (PSA) levels and reserving MRI-targeted biopsy for those with PI-RADS scores of 3 to 5 reduced the risk of detecting clinically insignificant cancers by half.

In a recent video interview from the Radiological Society of North America (RSNA) conference, Tessa Cook, MD, PhD discussed new research on automated de-identification in radiology reports and the potential of artificial intelligence (AI) and natural language processing (NLP) to help address time-consuming challenges in the radiology workflow.

In a new study based on five- to six-year follow-up data from over 650,000 children and young adults who had at least one computed tomography (CT) exam prior to the age of 22, researchers found a “strong dose-response relationship” between increased CT radiation exposure and brain cancer.
