Owner resilience and home health

X-rays, ultrasound, CT and MRI

Understand what imaging can show and why the vet chooses one method.

Compare the methods

X-rays use ionising radiation to show structures such as bones and aspects of the chest/abdomen. Ultrasound uses sound waves to examine soft tissues and sometimes guide sampling. CT combines X-ray information into detailed cross-sectional images. MRI uses magnetic fields/radio waves and is often useful for brain, spinal and other soft tissues.

Preparation and safety

Positioning, movement, pain and scan length determine whether sedation or anaesthesia is needed; CT/MRI commonly require it. Ask about preparation, monitoring and recovery. Tell the team about implants and current medicines. Never assume an awake scan is always appropriate or safer.

Understand limitations

Each method answers different questions; clearer images do not guarantee a diagnosis or replace examination/laboratory tests. Ask what the chosen scan could change, whether specialist interpretation is needed and what happens if findings are uncertain. After sedation/anaesthesia.
