Diagnostic imaging modalities

Radiography

uses film images of internal structures (commonly referred to as x-ray)

radiopaque: substances that don’t allow x-rays to pass through

radiolucent: substances that allow the passage of x-rays

Computed tomography

ionizing radiation is used to produce a cross section of a tissue

painless and noninvasive

Magnetic resonance imaging

radio wave pulses and magnetic fields are used to produce a notable soft tissue resolution, which differentiates adjoining structures

Ultrasonography

Otherwise known as ultrasound imaging or sonography

makes use of high frequency sound waves to produce images of deep body structures

Fluroscopy

uses a fluoroscope to visually examine an internal organ

can produce continuous images of internal structures, even with movement

Contrast imaging

Radiopaque materials are used to visualize internal structures on x-ray images

a contrast medium may be used to enhance visualization

Nuclear imaging

Uses radiopharmaceuticals to form an image of an organ or system
