Ethicists sound off about lung cancer CT screening
Last year, the lung CT screening debate got jolted by claims from the International Early Lung Cancer Action Program that 80% of people with lung cancer that is treated early can live another decade, at least.

But radiologists must use the technology wisely, according to a comment in the January issue of the American Journal of Roentgenology, because radiation exposure of even as little as 2.5 to 9 mGy has been associated with an increase in cancer.
Dr. Howard Forman of Yale University and Dr. Christoph I. Lee of Stanford University wrote that radiation-induced lung cancer is most problematic for patients in their mid-50s, and smokers may be particularly vulnerable. Repeated CT procedures would significantly increase cancer risk and possibly result in thousands of radiation-induced lung cancers.
Radiologists have an obligation to inform patients of the risks, including workup of potentially benign lesions, they wrote.
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.
