Kidney Ultrasonography To Know More About The Kidney
A kidney ultrasonography is a noninvasive test that allows visualization of the kidneys to evaluate the size, shape, and location of the kidneys and also to assess blood flow to the kidneys.
During the test, a transducer is used to send very high frequency sound waves. The sound waves move through the skin to the organs of the abdomen and eventually gets bounced off by the organs like an echo to the transducer. The transducer receives the reflected waves that are processed electronically to produce images of the organs.
The technology behind ultrasound is that the different types of body tissues affect the speed at which sound waves travel. The speed at which the sound waves are reflected back to the transducer helps the doctor is further diagnosis. To evaluate the blood flow to the kidney, a Doppler probe is used within the transducer. The Doppler probe evaluates the velocity of and direction of blood flow in the vessel by making the sound waves audible. The rate of blood flow within a blood vessel is determined by the degree of loudness of the audible sound wave. An obstruction of blood flow may be indicated by the absence of these sounds.
Kidney Ultrasonography Is Done For The Following Reasons:
During the test, a gel is applied to the skin for smooth movement of the transducer over the skin and to eliminate air between the skin and the transducer.
