Radiologist
Physician who specializes in diagnosing and treating diseases and disorders with the X-ray and other forms of radiant energy
Radiology
Creates an image of hard tissue internal structures by the exposure of sensitized film to x-radiation
Magnetic resonance imaging
Uses a combination of radio waves and a strong magnetic field to produce images
Computed tomography
Uses x radiation with computer assistance to produce multiple cross-sectional views of the body
Radiography
Uses x radiation passing through the patient to expose a film or create a digital image that shows the body in profile
Radiolucent
Allows X-rays to pass through and appears black or dark gray on the resulting film
Radiopaque
Substance does not allow X-rays to pass through and appears white or light gray on resulting film
Pericardiocentesis
Puncture of the pericardial sac for the purpose of removing fluid.
Cardiocentesis
Puncture of a chamber of the heart for diagnosis therapy
Arthrocentesis
Surgical puncture of a joint space to remove synovial fluid for analysis to determine the cause of pain or swelling in a joint.

Ven
Vein
Intravenous contrast medium
Injected into a vein to make the flow of blood through blood vessels and organs visible
Tom/o

Tomography
The use of X-rays or ultrasound to produce a cross-section of the body
Intraoral radiography
The film is placed within the mouth and exposed by a camera positioned next to the exterior of the cheek
Panoramic radiograph/panorex
Shows all the structures in both dental arches in a single film
Radio graphic projection
Describes the path that the X-ray beam follows through the patients body from the entrance to exit
Low HB
Indicates lower than normal hemoglobin concentration due to anemia, recent hemorrhage or fluid retention
High HB levels
Higher than normal he,ogle in concentration in the plasma due to polycythemia or dehydration
