Bone Scan
How does it work?
- Uses a tiny amount of radioactive materials called "tracers". They are administered to patients and allowed to circulate and be absorbed by the bones.
- Produces two-dimensional images of the body
-
- Once absorbed, the patient lies on a table while a machine passes a gamma camera over the body to record the pattern of tracer absorption by the bones.
What does it show?
- Used to examine the skeleton to detect abnormalities
- Extremely sensitive to abnormalities and variations in bone metabolism, can scan the entire skeleton
- Radiologists look for abnormal bone metabolism on the scan, areas show up darker or lighter where tracers have or have not accumulated.
What is it used for?
Bone scans are a noninvasive medical test used to produce images of the bones that help diagnose and track several types of bone disease.
X-Ray
How does it look?
The Images shown by an X-ray are 2-dimensional pictures and examine the bones, lungs, teeth, breast, blood vessels heart, and digestive tract.
How does it work?
The way the an X-Ray work is by a machine that sends individual X-Ray particles called photons through the body the photons pass though the body and the resulting images are recorded on a special film or a computer . Contrast materials used may produce an allergic reaction.
