Digital Radiography (X-ray)

Digital X-rays give our veterinarians a fast, high-resolution view inside your pet's chest, abdomen, and skeletal system — often in minutes, without the wait of traditional film.

Digital radiography (X-ray) is one of the most widely used and information-rich diagnostic tools in veterinary medicine. At Dog & Cat Hospital Calabasas, our digital X-ray system produces high-resolution images instantly that our veterinarians can zoom, adjust contrast on, and share with board-certified specialists for telemedicine consultation — all without the chemical processing and delays of traditional film. Radiographs are used to evaluate the skeleton, chest (heart size, lung fields, fluid), and abdomen (organ size and shape, masses, bladder stones, and foreign material) in both dogs and cats. They are frequently the first imaging step when a pet arrives with pain, difficulty breathing, or suspected ingestion of something it shouldn't have.

Why It's Recommended

X-rays are recommended across a wide range of clinical situations because they provide structural information that a physical exam alone cannot:

  • Limping, bone pain, or joint swelling — evaluating for fractures, luxations, arthritis, or bone tumors
  • Difficulty breathing, exercise intolerance, or heart murmur — assessing heart size, lung patterns, and pleural (chest) fluid
  • Suspected foreign body ingestion — finding objects in the esophagus, stomach, or intestines (note: most plastics and fabrics are not visible on X-ray; ultrasound complements when needed)
  • Abdominal swelling, vomiting, or constipation — evaluating organ sizes, gas patterns, and obvious masses
  • Pre-surgical planning and post-operative implant checks (orthopedic plates, screws)
  • Pre-anesthetic chest X-rays in older pets or those with respiratory signs

What It Detects

Radiographs excel at visualizing structures with high density contrast:

  • Bone: fractures, arthritis, bone infection (osteomyelitis), bone tumors, and joint disease
  • Heart and lungs: enlarged heart chambers, lung consolidation or masses, fluid in or around the lungs, and tracheal changes
  • Abdomen: kidney and spleen size and shape, bladder stones (most are visible), intestinal gas patterns suggesting obstruction, and large masses
  • Foreign material: metal, gravel, and bone fragments; soft foreign bodies are not visible but may produce secondary gas patterns
  • Dental: digital dental X-rays (a specialized variant) reveal root fractures, bone loss, retained roots, and abscesses not visible above the gumline

How It Works

Digital radiography uses the same physics as traditional X-ray — a beam of ionizing radiation passes through the body and is captured on a detector — but the image appears on a computer screen within seconds:

  • Your pet is gently positioned on a padded table in the view required (on their side, on their back, or upright)
  • A brief, low-dose X-ray pulse is emitted and captured by the digital detector beneath the table
  • The image appears immediately on a monitor for our veterinarian to evaluate and manipulate digitally
  • Multiple views (typically two to three per region) are taken to provide full three-dimensional information
  • Images can be instantly sent to a radiologist or specialist for a formal read when complex interpretation is needed

The entire imaging session for a standard two-view chest or abdominal series takes 5–15 minutes.

Preparation

In most cases, no special preparation is required for routine radiographs:

  • Pets can eat and drink normally unless the X-rays are being taken as part of a procedure requiring anesthesia
  • Sedation may be recommended for painful patients, very anxious pets, or when perfect positioning is critical — limb X-rays for fractures, for example, often require sedation for the pet's comfort and safety
  • For abdominal X-rays, a recent bowel movement is helpful but not required; gas and fecal material can obscure some details
  • Let us know if your pet is pregnant — we minimize exposure and will discuss the clinical necessity vs. alternatives

What to Expect

Most radiograph appointments are quick and straightforward. A veterinary technician gently positions your pet with foam wedges and sandbags for consistent, diagnostic views. Many dogs and cats hold still without issue; some need brief physical restraint or gentle sedation. The X-ray pulse itself lasts a fraction of a second and is completely painless — pets are unaware it is happening. Results are reviewed immediately by our veterinarian, and you'll receive a clear explanation of what was found and what the next steps are before leaving. Complex cases are sent to a board-certified veterinary radiologist for a formal written report within 24 hours.

Is It Safe?

Digital radiography exposes pets to a very small, brief dose of ionizing radiation — far lower than traditional film X-ray and vastly lower than CT scanning. The dose from a standard two-view radiograph is negligible relative to any clinical benefit. Occasional X-rays for diagnostic purposes carry no meaningful health risk in dogs or cats. We follow ALARA principles (As Low As Reasonably Achievable), using the minimum number of views needed for a confident diagnosis. Pregnant animals are imaged only when the clinical question cannot be answered another way, as the developing fetus is more sensitive to radiation.

Frequently Asked Questions

1Will my dog or cat need to be sedated for X-rays?
Many pets tolerate routine X-rays without sedation using gentle positioning and a calm approach. Sedation is recommended when a pet is painful — since positioning requires manipulating an injured limb — or very anxious, to ensure accurate, diagnostic images and protect the patient from additional injury.
2Can X-rays detect everything in my pet's abdomen?
X-rays excel at showing differences in density — they reveal bone, air, fluid, and dense soft tissue masses well, but struggle to differentiate between soft tissue structures of similar density (for example, the texture of the liver or spleen). Abdominal ultrasound complements radiography by providing soft-tissue detail that X-rays cannot.
3My dog swallowed something — will it show up on X-rays?
Metal objects, gravel, and bone fragments are clearly visible on X-rays. Most plastics, fabric, and rubber items are not — but the secondary effects, like a dilated, gas-filled intestinal loop, can suggest an obstruction. Ultrasound or endoscopy may be needed when the object itself isn't visible.
4How much do pet X-rays cost?
Cost depends on the number of views taken and whether sedation is required. A standard two-view series is less expensive than a full orthopedic series covering multiple limbs and joints. We'll discuss what's needed and the associated cost before imaging. Contact our team for pricing.
5Are X-rays safe for my pregnant dog?
We minimize X-ray exposure in pregnant animals when possible because the developing fetus is more radiosensitive than adult tissue. When the clinical question is urgent and cannot be answered by other means, we take the minimum number of views needed. We'll always discuss the clinical need versus alternatives with you first.
6Can X-rays detect cancer in dogs and cats?
X-rays can reveal bone tumors, lung masses, and large internal masses, and are a key part of cancer staging (particularly looking for lung metastases). They are not sensitive enough to detect small or early soft-tissue tumors, which is where ultrasound, CT, and biopsy add information.
7How quickly will I get the X-ray results?
Our veterinarians review digital radiographs immediately and discuss findings with you at the same appointment for most cases. When a board-certified radiologist is consulted for complex or equivocal findings, a formal written report is returned within 24 hours.
