Here Are The Questions You Should Ask Before Every CT Scan

What other questions do parents need to pose to doctors to ensure that their child is receiving a safe and necessary CT Scan?

Dr. Greene’s Answer:

CT’s are wonderful, lifesaving technology, but as with antibiotics, it is wise to ask if there is a safe way to diagnose the situation without a CT. If a CT is recommended, it is wise to ask that a child-appropriate level of radiation be used, to cut the radiation risk in half.

  • Is a CT scan the best examination for my child?
  • How will the CT scan be adjusted based on my child’s size?
  • Will a radiologist be involved in my child’s CT scan?

Some radiologists practice ALARA (As Low As Reasonably Achievable) – a commitment to using the lowest dose of radiation that will do the job well).
