Introduction

Ultrasound is a safe, painless and radiation free examination technique using high frequency sound waves to produce still and live pictures of internal organs and systems. With all ultrasound exams, a handheld microphone like device a transducer is scanned over the part of the body being examined. As the sound waves make contact with blood, tissue and bone, portions of the waves ”echo” back to the transducer. The echoes are then analyzed by a computer to form continuous real-time images and videos.
Your examination (scan) will be performed by a Radiologist or by a Sonologist. They will start by asking you some brief questions about your medical history, current symptoms and you will be asked to lie down on a the table and apply a clear water soluble gel to the part of the body to be examined. The gel helps the sound waves travel from the ultrasound machine through the skin, down to the tissues that are the target of the study. After applying the gel, the sonologist will guide the transducer – a handheld instrument – slowly across your skin while watching a continuous image on a computer screen.

You may feel some mild discomfort during examination.

Patient doesn’t need to discontinue medication.
