medical imaging
procedures that allow visualization of strutures inside our bodies
a single barrage of x rays passes through the body, producing an image of interior structures on x ray sensitive film--x ray; inexpensive, quick, simple to perform; bones appear white, hollow structures appear black (examining soft tissues-mamography; bone density-bone densitometry)
magnetic resonance imaging (MRI)
body is exposed to a high-energy magnetic field, which causes protons in body fluids and tissues to arrange themselves in relation to the field; pulse of radio waves "reads" ion patterns & a color-coded image is assembled -- 2 or 3 dimensional blueprint of cellular chemistry. safe--cannot be used on paitiens with metal in their bodies, best for differentiating soft tissues
ultrasound scanning
high-frequency sound waves produced by a handheld wand reflect off body tissues and are detected by the same instrument; image is called a sonogram--noninvasive & painless
radionuclide scanning
a radioactive substance is introduced intravenously into the body and carried by the blood to the tissue to be imaged; gamma rays emitted are detected by a gamma camera outside the subject and fed into a computer--study activity of a tissue or organ
visual examination of the inside of body organs or cavities using a lighted instrument with lenses called an endoscope
used to examine the interior of the colon
used to examine the organs within the abdominopelvic cavity
used to examine the interior of a joint, usually the knees
