Ultrasound Ultrasound or sonography is a way of obtaining internal images of the human body using high frequency sound waves to define anatomy in much the same way as sonar shows underwater structures. The echoes from the transmitted sound waves are captured and converted into a real-time, visual image. These real time images allow radiologists and sonographers to see movement of tissues and organs, as well as demonstrate blood flow and heart rate. Ultrasound is a painless procedure and produces very precise images of soft tissue. Because there are no known biological effects of ultrasound, we can also examine the health and well being of the unborn fetus quite effectively. Ultrasound is excellent for examining solid organs and fluid filled structures such as kidneys, gallbladder and liver. Color flow doppler imaging is also a powerful tool for evaluating blood vessels and blood flow in various structures. |
