An ultrasound is a non-invasive imaging procedure that enables an in-depth view of your cat's organs. Many times x-rays, which reveal the size, dimensions and position of the organ, will be utilized in combination with an ultrasound. The ultrasound allows for the evaluation of internal organs and is a highly useful tool in evaluating heart conditions (referred to as echocardiogram), detecting alterations in abdominal organs and assisting in the recognition of tumors.
Anesthesia or sedation is not usually necessary to perform an ultrasound, but if your cat is fearful or anxious, a sedative may be recommended. The hair on the belly (or under the right front leg for an echocardiogram) must be shaved to allow for quality imaging, but don't worry, it generally grows back in a matter of months.
