Ionizing or not?

Use this for “Which of X-ray, CT, PET, SPECT, MRI, ultrasound and OCT expose the patient to ionizing radiation?”

Sort

Does each method expose the patient to ionizing radiation?
Tap a card, then tap its group.

Assumptions

•
Ionizing radiation (X-rays and gamma rays) carries enough energy to knock electrons off atoms, so its dose is kept low.
•
Magnetic fields, radio waves, sound and near-infrared light do not ionize.
•
PET and SPECT show function (where a tracer goes); the others mostly show anatomy.
