Dopplerultrahangot

Dopplerultrahangot, commonly referred to as Doppler ultrasound, is a non-invasive medical imaging technique that utilizes the Doppler effect to assess the blood flow within the body. This method builds upon conventional ultrasound by incorporating the principle that the frequency of a sound wave changes when it reflects off a moving object. In the context of Doppler ultrasound, the sound waves are emitted by a transducer and then bounce off circulating red blood cells.

The reflected sound waves return to the transducer with a shifted frequency. This frequency shift, or Doppler shift, is directly proportional to the velocity and direction of the blood flow. A trained sonographer can interpret these shifts to create a visual representation of blood flow, often displayed in color. Red typically indicates blood flowing towards the transducer, while blue signifies flow away from it. The intensity of the color can also correlate with the speed of the blood.

Doppler ultrasound is crucial in diagnosing a wide range of conditions affecting blood vessels. It is frequently employed to detect blockages in arteries, such as those in the legs or neck, which can indicate peripheral artery disease or carotid artery stenosis. It is also used to evaluate veins for blood clots, a condition known as deep vein thrombosis (DVT). Furthermore, Doppler ultrasound plays a vital role in monitoring the health of fetuses during pregnancy, assessing blood flow to the placenta and the baby. Its applications extend to examining blood flow in organs like the heart, kidneys, and liver, aiding in the diagnosis of various pathologies.
