Ultrasound
Ultrasound imaging, also called ultrasound scanning or sonography, is a method of obtaining images from inside the human body through the use of high-frequency sound waves. The reflected sound wave echoes are recorded and displayed as a real-time visual image. No X-ray is involved in ultrasound imaging.
Ultrasound
is a useful way of examining many of the body's internal organs, including
but not limited to the heart, liver, gallbladder, spleen, pancreas, kidneys
and bladder. Because ultrasound images are captured in real time, they
can show movement of internal tissues and organs and enable physicians
to see blood flow and heart valve functions. This can help to diagnose
a variety of heart conditions and to assess damage after a heart attack
or other illness.Ultrasound has difficulty penetrating bone and therefore can only see the outer surface of bony structures and not what lies within. For visualization of bone, other imaging modalities such as magnetic resonance imaging (MRI) may be selected.
