Ultrasound

Ultrasounds do not use radiation, which is why procedure is widely used during pregnancy, but it can also be used to detect soft tissue issues and diagnose a variety of other conditions, including those in the pancreas, thyroid kidneys, bladder, liver, gallbladder, heart, blood vessels, spleen, uterus, ovaries, eyes and more. 

Sometimes called sonography, ultrasounds bounce high-frequency sound waves off the body to produce a real-time picture of the internal structures including organ formation, movement and blood flow.
