No shield from x-rays: How science is rethinking lead aprons
CHICAGO - Patients have come to expect a technician to drape their torsos with a heavy lead apron when they get an x-ray, but new thinking among radiologists and medical physicists is upending the decades-old practice of shielding patients from radiation.

National and state neighborhood-level disadvantage rankings of the study patients. (A) National disadvantage rankings are shown. Left: area deprivation scores mapped onto the state of Wisconsin, where the study sample resides, with national ranking deciles shown. Blue indicates less disadvantaged neighborhoods, whereas red indicates more disadvantaged neighborhoods. Right: histogram quantifying the number of patients in each Area Deprivation Index (ADI) decile. (B) Same as A, but state ranking deciles are shown. The distributions of both the national and state-level ADI rankings of the patients were skewed toward less disadvantaged neighborhoods. Maps were obtained from reference 36.

For each panel, top row shows fused PET/CT images, middle row shows PET-only images, and bottom row shows unenhanced CT images. Target lesions are highlighted by white arrows on fused/CT images and black arrows on PET images.
