Ultrasound is a morphological and dynamic examination. Sometimes, an additional Doppler ultrasound – an absolute functional exploration coupled with ultrasound investigation – is relevant to explore the vascularization of organs.
Ultrasonography shows organs through the use of ultrasound. A probe emits ultrasounds. The latter cross tissue and come back in the form of an ultrasound depending on obstacles encountered. The result is a signal which is collected and analysed by a computer system. An image is then sent directly to a video screen.
