Which of the following medical imaging modality other than ultrasound

1.	Which of the following medical imaging modality other than ultrasound does not use any form of radiation?(a) PET Scan(b) SPECTScan(c) CT Scan(d) MRIThe question was asked in quiz.This intriguing question comes from Ultrasound topic in section Diagnostic Investigation via Imaging Techniques of Clinical Science
Answer» The correct ANSWER is (d) MRI The explanation: MRI uses the electromagnetism of the ATOMS present in the BODY to get the images while all the other imaging modalities use some SORT of radioactivity in order to take the images. Ultrasound relies on the sound waves while MRI relies on the electromagnetic waves. Thus, they are both non RADIOACTIVE imaging modalities.
