Kann man den Kopf mit Ultraschall untersuchen?
Die Ultraschalldiagnostik (Sonographie) in der Neurologie beinhaltet die Beurteilung der den Kopf und das Gehirn versorgenden Schlagadern (Arterien) mit der sogenannten Doppler- bzw. Farbduplexsonographie.
Wie kann man die Hirndurchblutung messen?
Mit einem in der PTB entwickelten Messverfahren der Nahinfrarotreflektometrie und -spektroskopie lässt sich unterscheiden, ob Durchblutungsveränderungen in der Großhirnrinde oder in darüber liegenden Gewebeschichten (Haut, Knochen) ablaufen.
What do you need to know about a sonogram?
A sonogram, also known as an ultrasound, is an imaging test that uses sound waves to create pictures of organs, tissues, and other structures inside the body. Unlike x-rays, sonograms don’t use any radiation. A sonogram can also show parts of the body in motion, such as a heart beating or blood flowing through blood vessels.
What kind of equipment does a sonographer use?
Some of the technologies sonographers use on the job range from A-Mode ultrasound machines to pulsed-wave Doppler ultrasound units, according to O*NET (2020). They also typically use a small tool called a transducer that is placed upon a patient’s skin in the area to be imaged.
What can a pregnancy sonography test tell you?
Pregnancy sonography is used to look at an unborn baby. The test can provide information about a baby’s growth, development, and overall health. Diagnostic medical sonography is used to view and provide information about other internal parts of the body.
Why is sonography the safest of the imaging tests?
While the energy of the ultrasound waves could potentially irritate or disrupt tissues with prolonged exposure, the computer modulates the power of the sound and a trained technician uses techniques to minimize exposure times and angles. So, sonography is the safest of the imaging tests.
