Second Take: Notify patients of radiation risk from CT scans
Should patients scheduled for CT scans be notified of the risk of radiation-induced cancer? In this Second Take article, Dr. Ian Amber and Dr. Po-Hao Chen take the position that obtaining patient consent before performing a CT scan is a necessary task for any responsible imaging provider.

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.
