Medical Imaging :

Which is the most common form of medical imaging, using high-energy radiation to penetrate skin and tissues but not bone?

• X-ray

• Ultrasound

• Magnetic Resonance Imaging (MRI)

• Positron Emission Tomography (PET)

This is an X-ray of a knee joint.

Why does bone appear white on X-rays?

• X-rays cause a chemical reaction in bone that makes it glow white

• X-rays are absorbed by bone

• X-rays are reflected off bone

• X-rays excite the atoms in bone so that they glow white

Which of these imaging techniques use X-rays?

A) Radiography

B) Fluoroscopy

C) Radiotherapy

D) Ultrasound

E) Computed Tomography (CT)

F) Magnetic Resonance Imaging (MRI)

G) Positron Emission Tomography (PET)

• C, E and F

• D, F and G

• A, B, C, and E

• All seven techniques use X-rays

Which imaging technique uses sound waves to bounce off tissues and reflect back to a transducer?

• Biophotonics

• Positron Emission Tomography (PET)

• Computed Tomography (CT)

• Ultrasound

What is ( MRI ) ?

• is a penetrating form of high-energy electromagnetic radiation.

• also called sonography or diagnostic medical sonography, is an imaging method that uses sound waves to produce images of structures within your body.

• medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body.

• medical imaging technique used in radiology to obtain detailed internal images of the body noninvasively for diagnostic purposes.
