Radiography
|
X-rays pass through the body
Dense structures appear white Hollow structures appear black |

|
Magnetic Resonance Imaging
|
High-energy magnetic field causes PROTONS in body fluids and tissues to arrange themselves in relation to the field
Pulse of radio waves read these patterns No radiation |
|
|
Computer Tomography
|
X-ray beam traces an arc at multiple angles around a section of a body then a computer assembles transverse section of the area.

|
Ultrasound Scanning
|
wand emits ultrasound waves that are reflected off body structures and then detected by the same instrument
Fetal monitoring, visualization of organs and blood flow |
|
|
Positron Emission Tomography
|
Substance that emits positrons injected into the body, the collisions of positrons with electrons in tissue produce gamma rays which are detected by gamma cameras
physiology of organs |
|
|
Radionuclide Scanning
|
radioactive substance injected then carried to an organ
gamma rays emmited are detected by gamma camera Used to study activity of tissue and organs |
|
|
Endoscopy
|
