Venous Ultrasound To Detect Blood Clot In The Veins
Ultrasound imaging uses very high frequency sound waves to obtain images of structures inside the body. When the waves are focused at a particular body part, they get bounced back from different types of tissues and blood fluid. The reflected echoes form images of the veins that carry blood from organs to the heart.
Venous ultrasound is a technique to capture real-time images of blood flow through the blood vessels. Venous ultrasound exam is performed to detect blood clot which can cause pulmonary embolism. This is caused when blood clots break off and pass into the lungs. If detected on time, there are suitable treatments to prevent Pulmonary embolism.
Venous Ultrasound Is Performed To:
In venous ultrasound when the transducer is pressed against the skin, it directs high frequency sound waves towards the veins which are being examined to observe changes in the characteristics of the returning echoes. These echoes are transmitted electronically to capture real time images on the monitor.
However, it is not possible to capture images of the veins lying deep beneath the skin, especially in the calf. It is difficult to evaluate whether the blood clot ahs closed off the vein or blood can pass through.
This technique has shown rapid growth and acceptance in the medical community. Venous ultrasound is a simple technique without any side-effects.
