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.
New MRI Research Explores Links Between Waist-to-Hip Ratio and Memory in Aging
March 13th 2025Researchers found that a higher waist-to-hip ratio in midlife was associated with higher mean diffusivity in 26 percent of total white matter tracts in the cingulum as well as the superior and inferior longitudinal fasciculus.
Can Ultrasound-Based Radiomics Enhance Differentiation of HER2 Breast Cancer?
March 11th 2025Multicenter research revealed that a combined model of clinical factors and ultrasound-based radiomics exhibited greater than a 23 percent higher per patient-level accuracy rate for identifying HER2 breast cancer than a clinical model.
