wk 10 Diagnostic Imaging: Radiology and Ultrasound for the Veterinary Assistant

A set of flashcards covering key concepts from diagnostic imaging in veterinary assisting, focusing on radiology and ultrasound procedures.

What is the role of a veterinary assistant in radiology?

To assist the radiology technician using proper technique and restraint to acquire images for the veterinarian.

What does kVp stand for in radiology?

Kilovoltage, which regulates the energy of the x-ray beam.

How does increasing kVp affect the film?

It increases the penetration of tissue and darkens the film.

What is the purpose of milliamperage (mA) in x-ray machines?

It controls the quantity of electrons in the x-ray tube and affects the amount of x-ray produced.

What is the difference between manual and digital radiographs?

Manual uses x-ray film with processing, while digital uses computerized systems and does not require film cassettes or a dark room.

What is the exposure time in radiography?

It regulates the quantity of x-ray reaching the film and affects the density of the image.

What safety gear is important when handling chemicals in radiography?

Protective gear, including eye wash stations, gloves, and goggles.

What is the function of a caliper in radiography?

To measure the thickness of the body part being x-rayed for proper setting adjustments.

How does patient positioning affect x-ray imaging?

Proper restraint and positioning minimize stress on the patient and ensure accurate images.

What materials must be used to clean the radiography cassette?

Soap/water, canned air, dilute ethyl alcohol, or a commercial cleaner.

What does ultrasonic imaging allow veterinarians to visualize?

Organ shape, structure, blood flow, and movement within the digestive tract.

What position should a patient be in for abdominal ultrasound?

Ventral recumbency in a padded positioning trough.

What should be done to the patient's fur before conducting an ultrasound?

The area should be shaved, and ultrasound gel or alcohol should be applied.

What information is recorded in an x-ray log?

The patient's details, machine settings, and names of the technicians or assistants present.

What is one advantage of digital radiography compared to traditional methods?

Radiographs can be easily viewed from all computers in the practice.

What is the purpose of the light used during the x-ray process?

To collimate or regulate the size of the image.

What procedures must be followed in film processing?

Developing, washing, fixing, and drying the film in a dark room.

What is a key safety consideration when changing film processing chemicals?

To wear protective gear as a drop of fixer concentrate can harm the eyes.

What is an example of a preparation needed for cardiac ultrasound views?

Shaving the chest area and applying ultrasound gel.

How are ultrasound images typically archived?

They may be saved on a computer for future reference.
