Veterinary Nursing: Diagnostic Imaging

Vocabulary flashcards focused on veterinary nursing and diagnostic imaging techniques.

Computerised Tomography (CT)

A technique that uses x-rays to produce highly detailed cross-sectional images of the patient's tissues.

Radionuclide

An atom that disintegrates and emits gamma radiation.

Radiopharmaceuticals

Medical products used in examination techniques that contain radioactive materials.

Half life

The time taken for the radioactivity of a substance to decay to half its original value.

Magnetic Resonance Imaging (MRI)

An imaging technique that uses magnetism and radio waves instead of ionizing radiation to produce images of tissues.

Anaesthesia in MRI

Animals must be anaesthetised to keep them still during the scan because it can take up to an hour.

RF coil

A device used in MRI to detect radio signals emitted by tissues in the magnetic field.

Scintigraphy Uses
