Radiographic Contrast Studies in Veterinary Medicine

These vocabulary flashcards cover key concepts and terminology related to radiographic contrast studies in veterinary medicine, providing definitions and explanations to aid in exam preparation.

Radiograph

An image produced by X-rays used to diagnose conditions in animals.

Contrast Studies

Additional imaging studies using contrast agents to enhance visibility in radiographs.

Upper GI Study

A radiographic examination of the stomach and small intestine using contrast agents.

Lower GI Study

A radiographic examination focused on the rectum, colon, and large intestine.

Positive Contrast Study

A type of radiographic study that uses a contrast agent to make structures appear radiopaque.

Negative Contrast Study

A radiographic study that uses air or gas to make structures appear radiolucent.

Mixed Contrast Study

A study that combines both positive and negative contrast agents.

Insoluble Inert Medium

Barium, used in upper and lower GI studies due to its opacity.

Soluble Nonionic Medium

Iohexol, commonly used in CT studies, safe for use in myelograms.

Soluble Ionic Medium

Ionic contrast agents used primarily for renal studies and myelograms.

Radiolucent Gases

Gases such as air or carbon dioxide used in negative contrast studies.

Barium Impregnated Polyethylene Spheres (BIPS)

Insoluble agents used to evaluate motility time in GI studies.

Fluoroscopy

A real-time imaging technique that allows visualization of movement through organs.

Myelogram

A radiographic study used to visualize the spinal cord and nerve roots.

Aspiration

Inhalation of a foreign substance into the lungs, posing health risks.

Peritoneitis

Inflammation of the peritoneum, often due to leakage from perforations.

GI Study

A general term for studies focused on the gastrointestinal tract.

Survey Radiograph

Initial radiographs taken before administering contrast agents.

Sedation Precautions

Care taken to avoid sedation in GI studies due to its effects on motility.

NPO

Nil Per Os; the patient must not eat or drink before procedures.

Enema

A procedure used to cleanse the bowel prior to radiographic studies.

Contrast Agent

Substance used to enhance imaging studies for better visibility.

pH of Contrast Agents

Importance of selecting the appropriate contrast agent based on chemical makeup.

Mortality Risks

Potential serious complications like pulmonary embolism from improper contrast use.

Timing of Contrast Administration

The intervals at which images are taken post-contrast to evaluate movement.

Patient Positioning

The specific way a patient is positioned during radiographic studies for optimal results.

Imaging Technique

Methods used to obtain clear images during radiographic studies.

Barium Solution

Liquid form of barium administered for upper GI studies.

Contrast Study Procedure

Step-by-step protocol for conducting a successful contrast radiographic study.

Image Interpretation

The ability to analyze radiographs and identify abnormalities.

Patient Selection

Choosing appropriate patients for radiographic studies based on clinical signs.

Obstruction Identification

Using contrast studies to determine if there are blockages in the GI tract.

Congenital Disorders

Conditions present at birth that may affect gastrointestinal motility.
