Preparing for an Ultrasound Exam

General Ultrasound

• Wear loose-fitting clothing.
• Follow your doctor’s instructions. Some ultrasound exams require you not to eat or drink before the exam; other ultrasound exams require you to drink extra fluids prior to the exam.

OB Ultrasound

• Wear loose-fitting, two-piece clothing to allow easy access to the abdomen
• Drink up to six glasses of water the hour before your exam IF you are instructed to do so by your doctor (usually in early pregnancy). In most cases, a full bladder during the exam is not necessary
• Empty your bladder before a transvaginal ultrasound (transducer is inserted into the vagina).
