Imaging technologies

electrocardiology

reads the heart’s electrical impulses

radiography

uses x-rays to visualize internal structures

computed tomography(CT) scan

uses computers and x-rays to create 3-d images of internal structures

Magnetic resonance imaging (MRI)

analyzes tissue responses to a strong magnetic field to create images of internal structures

Ultrasound

analyzes the interaction of low-frequency sound waves with tissues to create moving images of internal organs

Nuclear medicine

 uses radioactive materials to create contrast in the body and help form images of the structure and function of organs

prognosis

the predicted course of a disease and its outcome, May state chances for complete recovery, predict permanent loss of function, or give probability of survival 

Acute disease

sudden onset and short duration

Terminal disease

disease that will end in death

Chronic disease

 slower, less severe onset and long duration
