Hurry up pl what do mri and ultrasound have in common as diagnostic imaging techniques? check all that apply.
low risk for tissue damage
uses radio waves
noninvasive
tomographic imaging
no radiation

1. low risk for tissue damage

2. Non invasive

3. No Radiation

Explanation:

MRI: Magnetic Resonance Imaging. In this diagnostic technique, powerful magnetic field and radio waves are used to make detailed pictures of body parts and tissues.

Ultrasound: In this technique sound waves of frequency more than 20000 Hz are used for imaging.

Both of these technique are non invasive, pose a very little threat to tissue damage and use no radiation. But differs in:

1. Use of radio waves: Only MRI technique uses radiation waves while Ultrasound uses sound waves.

2. Tomographic Imaging: Tomography imaging involves imaging by sectioning. But only MRI uses tomography imaging process.
