In veterinary medicine, X-rays are used to assess different conditions such as bone and joint, heart, respiratory, dental, and urinary diseases.
Occasionally, pets may be given a sedative in order for X-rays to be taken safely and accurately.
Ultrasonography is a non-invasive imaging technique, and unlike X-rays, it does not involve radiation. Ultrasounds are ideal for showing details of soft tissues, making this technique useful to assess organs such as the heart (echocardiography) and the organs (liver, kidneys, intestines) within the abdomen. As sound waves don’t travel well through air and bones, ultrasound scans have difficulty imaging body parts that contain gas, such as the lungs, or underneath the skull. For assessing these areas, other imaging tests such as MRIs, X-rays, or CT scans are appropriate.
An ultrasound can take up to 30 minutes or more. If your pet finds it uncomfortable to remain still, or to lie on their back for this whole period, sedation may be suggested to help them relax during the procedure.
