An ultrasonic imaging scan of the liver is known as a liver pathology ultrasound. High frequency sound waves are transmitted into your body during an ultrasound scan using a handheld device. These sound waves pass equally through your tissues until they come into contact with a tougher or softer tissue that has a varied tissue density. This can be blood, a cyst, a bone, or an organ nearby. The ultrasonic device (also known as a transducer) converts the information into an image when sound waves reverberate. According to the Food and Drug Administration (FDA) Trusted Source, ultrasound technology does not have the same hazards as X-rays or CT scans since it employs sound waves instead of ionising radiation to produce images. Radiologists are trained to interpret ultrasound images. They will typically examine your ultrasound images and relay their findings to your doctor. Changes to the expected size, shape, and structure of the liver could signal a concern or a need for further testing.
