by“Tomorrow’s World'' !!!!********

* Ultrasound, MRI, PET, X-ray computed tomography (CT), MEG :  Each one measures a different physical property of the sample.

Why use different methods of imaging ?

*Distinct procedures reveal distinct features.

*Ultrasound charts the reflection and attenuation of sound.

*X-ray CT assesses the X-ray attenuation coefficient of the body at each issue. factual 3-D images.

*PET charts the circulation of radioactively marked compounds.

*MRI charts the distribution and “environment” of water substances in the body.

*MRI journals the circulation and “environment” of water substances in the body.
