Advantages and Disadvantages of Ultrasonography

Advantages of Ultrasonography

1. It has no long term side effects and comfortable
2. It images the muscles, bone surfaces, soft tissues etc well
3. By using ultrasonic system, the physician can easily diagnose the various diseases.
4. Relatively inexpensive when compared with systems such as magnetic resonance imaging.
5. It shows the structure of organs.
6. Equipment is readily available and comparatively 'flexible.
7. Examinations can be performed at the bedside by using small and easily carried scanners.

Disadvantage of Ultrasonography

1. The performance of sonographic system degrades when there is gas between the transducer and the organ of interest It is due to the change in acoustic impedance.
2. The method of ultrasonography is operator dependent. A high level skill and experience - is needed for better imaging.
3. There may difficulties in imaging structures deeply in the body especially in abnormally fat patients.
4. Once an image has been acquired, there is no exact way to tell which part of the body was imaged.
5. A major disadvantage is that sonographic devices have the trouble of penetrating the bone.

Applications of Ultrasonography

1. Medical ultrasonography is used in the study of many different systems such as cardiology, ophthalmology, neurology etc.
2. Sonography is highly effective in imaging soft tissues of the body.
3. Ultrasound may be used to clean teeth in dental hygiene.
4. By using Focused Ultrasound Surgery (FUS) we can treat for tumors and cysts. Here focused ultrasound is used to generate highly localized heating.
5. Focused ultrasound can also be used to break up kidney stones.
6. Low intensity ultrasound exposure can help in stimulating bone-growth.
7. High Intensity Focused Ultrasound (HIFU) is used for the treatment of disease: such as cancer.
