CT Scan and Hair Loss
Hello Dr – I read with interest your answer about MRI scans and how there is no link from them to hairloss as they use magnets. What then, would be your opinion on CT Scans? Could these cause hairloss and if so over what time period? i.e – a few days after the scan or a few years? Thank you for your time.
The amount of radiation that a CT scan (also known as a CAT scan) will administer is not sufficient to cause hair loss. It takes much, much more radiation to cause radiation sickness and have the side effects to cause hair loss.

I work in the radiology dept in a hospital and wonder if this can cause hair loss, as I’ve noticed my hair has thinned since I started working here. any ideas? Thanks.
Reality would dictate otherwise. Did you hear about in 2010 they did an article on brain CT perfusion in California where they all had a band of hair loss after getting checked for strokes etc. normal CT of head is ok but a brain perfusion CTA test done improperly can cause hair loss and also a risk of glaucoma and cancer later in life although the cancer risk from one overdose I am not sure of
