How you prepare
By Mayo Clinic staffHow you prepare for an ultrasound depends on which area of your body needs evaluation:
- Some ultrasound exams require no preparation.
- Others require that you forgo food and liquids for up to six hours before the exam.
- Still others require that you not urinate before the exam to ensure that your bladder will be full, allowing better visualization of the uterus, ovaries or prostate.
When scheduling your ultrasound, ask your doctor for specific instructions for your particular exam.
