Types of ultrasound
Abdominal ultrasound: A hand-held device called a transducer is moved over gel on your lower abdomen. This is common in pregnancy and for looking at the pelvis.
What should I expect?
For an abdominal scan, your doctor applies gel to your lower abdomen and moves a transducer across your skin to produce images. For a transvaginal scan, a small transducer is placed gently in the vagina. You can ask for a chaperone for any exam.
