Worry over children's CT scans

A UK expert has reassured parents after American research suggested children undergoing CT scans may be receiving more radiation than is necessary

Increasingly, radiologists are trying to use MRI scans on children in preference to CT scans wherever possible.

"We wouldn't recommend giving a CT scan unless it's absolutely necessary."
