Unexpected findings from a study of Norwegian women who have and have not received routine biennial screening mammography suggest some breast cancers may spontaneously regress.
Dr. Per-Henrik Zahl, a senior statistician at the Norwegian Institute of Public Health in Oslo, and colleagues compared cumulative breast cancer incidence in agematched cohorts of women before and after the initiation of biennial mammography.
The initiation of screening mammography has been associated with increased breast cancer incidence among women of screening age, the researchers said. If all the newly detected cancers progressed and became clinically evident as women age, a fall in incidence among older women should follow, but such was not the case in this study. Results were reported in the Nov. 24 issue of the Archives of Internal Medicine (2008;168[21]:2311-2316).
MRI-Based AI Radiomics Model Offers 'Robust' Prediction of Perineural Invasion in Prostate Cancer
July 26th 2024A model that combines MRI-based deep learning radiomics and clinical factors demonstrated an 84.8 percent ROC AUC and a 92.6 percent precision-recall AUC for predicting perineural invasion in prostate cancer cases.
Breast MRI Study Examines Common Factors with False Negatives and False Positives
July 24th 2024The absence of ipsilateral breast hypervascularity is three times more likely to be associated with false-negative findings on breast MRI and non-mass enhancement lesions have a 4.5-fold likelihood of being linked to false-positive results, according to new research.
Can Polyenergetic Reconstruction Help Resolve Streak Artifacts in Photon Counting CT?
July 22nd 2024New research looking at photon-counting computed tomography (PCCT) demonstrated significantly reduced variation and tracheal air density attenuation with polyenergetic reconstruction in contrast to monoenergetic reconstruction on chest CT.
