Diagnostic Imaging for Veterinary Technicians

These flashcards cover essential vocabulary and concepts related to ultrasound imaging as presented in the lecture on diagnostic imaging for veterinary technicians.

Anechoic

Areas that do not generate an echo and appear black on the final image, usually representing fluid-filled structures.

Hyperechoic

Areas of high-intensity echo that appear very bright on ultrasound imaging.

Hypoechoic

Areas with little returning echo that appear darker gray.

Isoechoic

Areas returning echoes that are the same as the surrounding tissues.

Transducer

Device that generates sound waves and receives returning echoes in ultrasound imaging.

Gain control

Adjusts the strength of the returning echo in ultrasound imaging.

A-Mode

Amplitude mode; displays returning echoes as peaks, indicating their intensity.

B-Mode

Brightness mode; displays returning echoes as bright dots on the monitor corresponding to the intensity.

M-Mode

Motion mode; creates a B-mode image in motion often used in echocardiography.

Doppler ultrasound

Technique used to evaluate blood flow by measuring the velocity and direction of blood and other fluids.

Artifacts

Any result from ultrasound imaging that does not reflect the actual characteristics of the tissue or organ.

Frequency

The number of wave cycles that occur each second in ultrasound, measured in Hertz (Hz), kilohertz (KHz), or megahertz (MHz).

Wavelength

The distance between each band of sound waves in ultrasound imaging.

Acoustic Principles

The study of how electrical energy is converted to sound waves and how these waves interact with different tissues.

Patient preparation

The necessary steps to optimize ultrasound imaging results, including clipping hair and applying acoustic gel.

Clinical applications

Specific uses of ultrasound in veterinary medicine, including pregnancy diagnosis and injury detection.

Transducer types

Different configurations of transducers that affect the type of ultrasound image produced, such as linear or curvilinear.
