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.

PET brain scans from the same individual with early signs of Alzheimer’s disease comparing two tau radiotracers: flortaucipir, shown at top, and the investigational tracer MK6240, shown at bottom. Areas of pathological tau accumulation appear in red. The MK6240 scan shows more extensive tau buildup, suggesting that this tracer may detect Alzheimer’s-related brain changes that are less visible with the standard tracer.

Study highlights overconfidence in medical decision-making
By Liz Carey
Researchers expose metacognitive commonalities and differences between experienced radiologists and nonradiologists.
May 26, 2026
Bar graphs show mean success (blue) and confidence (orange) according to diagnostic response (lesion present or absent, shown as “present” and “absent,” respectively) and next-step decision (submit, additional tests, and consult a senior) for each group (radiologists and nonradiologists). Error bars indicate standard errors of the mean. Lesion-absent diagnoses were more prone to error and overconfidence than were lesion-present diagnoses.
