4. Ultrasound
• It is a diagnostic imaging technique
• It is used to create an image of internal body
structures such as tendons, muscles, joints,
blood vessels, and internal organs.

6. • Ultrasound are sound waves with frequencies
which are higher than those audible to
humans (>20,000 Hz).
• The ultrasound pulses echo off tissues with
different reflection properties and are
recorded and displayed as an image.

7. Advantages
• It provides images in real-time
– E.g, the motion of the beating heart of fetus
• It is portable
• It is substantially lower in cost
• It does not use harmful ionizing radiation.

8. Drawbacks
• Needs for patient cooperation
• Difficulty imaging structures behind bone and
air or gases
• Necessity of a skilled operator

9. Procedure
• Wear comfortable, loose-fitting clothing.
• remove all clothing and jewelry
• wear a gown
• abdomen examination – NPO
• examination of female reproductive organs take
more water to fill the bladder
• thick gel on the skin - good sound transmission

10. USG Can be used
to evaluate………

11. Heart
• To detect abnormalities in heart beats
• Structural abnormalities such as defective
heart valves
• Abnormal enlargement of the heart’s
chambers or walls

12. Blood vessels
To detect dilated and narrowed blood vessels

13. Gallbladder and biliary tract
To detect gallstones and blockages in the bile
ducts

14. Liver, spleen, and pancreas
• To detect tumors

15. Biopsy
• It can show the position of the instrument,
• area to be biopsied
• where to insert the instrument
• It can guide it directly to its target.

18. Doppler ultrasonography
Doppler ultrasonography uses changes that
occur in the frequency of sound waves when
they are reflected from a moving object (RBC)

19. Doppler ultrasonography can be used to
evaluate
• Whether blood is flowing through blood
vessels
• How fast it flows
• Which direction it flows in
