Just like x-ray, ultrasound has become quite common in medicine. This type of imaging utilizes sound waves to get pictures of the inside of a patient’s body. It can be used to diagnose the causes of swelling, pain, and infections.
Additionally, ultrasound can be used to examine a baby when a woman is pregnant. This type of imaging is safe, and it does not utilize ionizing radiation. It does not require any special preparation on the day you are to visit the doctor.
