THE MEDICAL IMAGING EXPERIENCE
INFORMATION FOR THE PATIENT
TRANSVAGINAL ULTRASOUND

WHAT IS IT?
Ultrasound procedures involve the use of very high frequency sound waves. The actual sound cannot be heard with the human ear. The sound waves are sent into the body using a hand held instrument called a transducer. The various structures in the body including organs, tissue and fluids (such as blood and water) reflect sound waves differently because of their different density. Some of the sound waves reflect back to the transducer much like your voice echoes back to you in an empty building. The reflected sound waves are received by the transducer and sent to a computer to be processed into pictures.

WHAT WILL HAPPEN TO ME?
The sonographer (the person who operates the ultrasound machine) will assist you as you lie on your back on a padded table. A bolster will be placed under your hips to elevate and tilt your pelvis. You will be given a condom covered, lubricated probe that you will insert into your vagina. The sonographer can assist you if help is needed. You will be draped with a sheet during the procedure to ensure your privacy. The sonographer will move the probe in various positions to view all the female anatomy. If a male sonographer performs the exam a female escort will be asked to be present during the exam.

HOW LONG WILL THIS TEST TAKE?
This ultrasound procedure usually takes 15 - 20 minutes to complete.

WHAT WILL I FEEL -- WILL IT HURT?
Usually the ultrasound room lights are turned down to darken the room. This helps the sonographer to see the video screen better. The procedure is generally not painful. You may feel some pressure during the exam.

WHAT WILL THE TEST SHOW?
The size, shape and arrangement of organs and other structures can be evaluated. Ultrasound can detect masses, cysts (fluid filled structures) or tumors.

HOW DO I GET READY?
The test is performed with an empty bladder so you will be asked to use the bathroom before the exam begins.
