Labs Flashcards
Xray
Electromagnetic radiation is used to visualize bones, tissues and blood vessels
Ultrasound
Sonogram nurses use sound waves to create images of internal parts of the body
MRI
Magnetic resonance imaging; can see through bone and provide images in multiple planes; uses radio waves; more detailed than CT scan
Pt must remain still; no pts with implantable metal devices such as pacemakers
CT Scan
Computed Tomography; fast series of xray pictures; much faster than MRI
Cultures and Sensitivities
Culture is used to figure out which microbe
Sensitivity tests what medicine is effective against it
