IMAGING

Radiographs (X-rays)

Imaging that helps evaluate bones, chest structures, abdominal patterns, heart silhouette and other anatomy when there is a relevant clinical question.

THE SHORT VERSION

Testing helps answer a clinical question.

Radiographs use controlled X-ray exposure to create images of internal structures. Chest, abdominal and orthopedic views answer different questions, and more than one positioning view may be needed.

01 · OVERVIEW

What is this test?

Radiographs use controlled X-ray exposure to create images of internal structures. Chest, abdominal and orthopedic views answer different questions, and more than one positioning view may be needed.

02 · WHAT IT EVALUATES

What information can it provide?

  • Chest radiographs can help evaluate lung patterns, heart silhouette, airways and fluid-related concerns.
  • Abdominal radiographs can assess organ outlines, intestinal gas, some foreign material, urinary stones and other structural patterns.
  • Orthopedic radiographs help examine fractures, arthritis, joint alignment and other skeletal concerns.
  • Appropriate positioning, several views and professional interpretation influence diagnostic value.
03 · WHY VETERINARIANS ORDER IT

When might your veterinarian recommend it?

  • Investigate cough, breathing changes, limping, trauma, abdominal pain or suspected obstruction.
  • Compare known disease progression or investigate a specific physical-examination finding.
  • Support an individualized baseline discussion when the veterinarian believes the information could change care.
04 · PREPARING FOR TESTING

What can owners do before the visit?

  • Ask whether fasting, sedation or careful handling is recommended.
  • Share prior imaging so the veterinarian can compare changes.
  • Tell the clinic about pain, breathing difficulty, pregnancy or prior anesthesia concerns.

05 · IMPORTANT LIMITATIONS

What can this test not tell you by itself?

  • Radiographs cannot identify every early disease or characterize all soft tissues.
  • One lateral image is not equivalent to a complete diagnostic study.
  • Not a universal screening recommendation: routine baseline radiographs of healthy animals are practice- and patient-dependent, not an automatic fixed-schedule requirement.

Do not change medication, interpret an abnormal number as a diagnosis or delay urgent treatment without direction from your veterinary team.

06 · TALK WITH YOUR VETERINARIAN

Useful questions for your appointment

  • What specific clinical question are these images intended to answer?
  • How many views are necessary, and would ultrasound or another test add information?
  • Is sedation recommended for safety, comfort or more accurate positioning?
