Ultrasound: Abdominal

Some reasons your doctor ordered your abdominal ultrasound

Common diseases the radiologist/sonologist might discover

How do you prepare for an abdominal ultrasound examination?

Nothing by mouth past midnight (except a small amount of water for medications).This prevents you from swallowing air (bad for ultrasound image) or increasing bowel activity. Any food could cause your gallbladder to contract. The radiologist wants your gallbladder full, and in its resting state.

What happens in the ultrasound laboratory?

You will probably change into a patient gown to prevent the ultrasound gel from staining your clothes. You will meet your sonographer, the person that will perform most of your scan. This trained technologist is an expert in ultrasound scanning. Most have been certified by the American Registry of Diagnostic Medical Sonographers(ARDMS). You will lie comfortably on an examination table. You may be asked to roll to either side. The sonographer squirts a special pre-warmed gel onto your skin that helps the sound penetrate into your body. This gel is harmless and easily wipes off after your examination. The transducer, or ultrasound scan head emits a very high frequency sound. The sound waves bounce off structures inside your body and are detected by the same ultrasound transducer. The ultrasound machine is a sophisticated computer that converts these reflected sound waves into images that are recorded by the sonographer and interpreted by the radiologist. Often, before you leave the examination room, the radiologist will come in to meet you and may also scan you in order to answer questions not fully answered on the initial ultrasound images.
