How should I prepare?
You should inform your physician of any medications being taken and if there are any allergies especially to iodinated contrast materials. Also inform your doctor about recent illness or other medical conditions.
You will be asked to remove some of your clothes and to wear a gown during the exam. You may be also be asked to remove jewelry, removable dental appliances, eye glassess and any metal objects or clothing that might interfere with the x-ray images.
If sedation is used for the procedure, you may be asked not to eat or drink anything for four to eight hours before your exam. Be sure that you have clear instructions from your health care facility.
Do not drive for 24 hours after your exam if sedation is used. Arrange for someone to drive you home. Because an observation period is necessary following intravascular ultrasound and the exam is often used in conjunction with another procedure, you should ask your doctor if you will need to be admitted to the hospital overnight.
