Radiation for CT scans

In the United States, currently about 10% of the population have a CT in one year.

Radiationj cancer induction is a real worry.

Radiation doses from CT scans are 100 to 500 times those from conventional radiography.

The better the image usually the greater the radiation dose.

I think that we should have national CT guidelines for dosage and that HIQA should inspect facilities nationwide to check doses.

Patients medical records should include the CT dosage used in investigations and follow-up
