nclear scans
used in diagnostic imaging (x-ray)
MRI
Magnetic Resonance Imaging
CT scan (CAT SCAN)
computed tomography
Ultrasound
the location, measurement, and delineation of deep body structures are measured by high-energy sound waves (ultrasonic waves) and makes echoes. A computer calculates the distance to the sound-reflecting or absorbing surface and gives a two-dimensional image on a screen
doppler
a diagnostic instrument that emits an ultrasonic beam into the body; the ultrasound reflected from moving structures changes in frequency. audible sounds rare heard
X-Ray
High energy radiation - used to diagnose diseases by making pictures of the inside of the body
hypodermic needles
never recap a used needle
always dispose of needles and anything sharp (scalpels) in the puncture-resistant sharps disposal container

2 containers
- a sealed leak-proof container with the specimen
