Why use cardiac CT for children when MRI delivers no radiation?

"As a radiologist, I'm always worried about dose. I'm not going to study children with CT. There is no good argument why cardiac CT has to be done in a child. MRI is such a great technique for congenital heart disease.

"Young people who will have multiple exposures are at maximum risk for developing cancers later in life. I recently read an article in a cardiology journal about using CT for children to measure ventricular volume. There was no comment in the article about radiation dose. I think that is criminal."
