Vessels10
Acoustic angiography overcomes the weaknesses of HFU by combining contrast-enhanced ultrasound with the use of a dual-element ultrasound transducer to achieve high resolution visualization of blood vessels at relatively deep penetration levels. (wikipedia.org)
Acoustic angiography is performed by first injecting specially designed microbubbles with a low resonant frequency into the vessels. (wikipedia.org)
Finally, a high-frequency transducer with high resolution is used to measure the super-harmonic frequencies, effectively removing any background signal from the microbubble signal, and allowing the vessels to be visualized Angiography, or the examination of blood vessels, is essential in many areas of research and clinical practice. (wikipedia.org)
In particular, angiography is needed to monitor angiogenesis, which is the growth and development of new blood vessels. (wikipedia.org)
In both cases, angiography is essential for measuring the growth, recession, or shape of blood vessels in-vivo over time during these treatments and related research Currently, the most common techniques used for angiography are X-ray CT and MRI. (wikipedia.org)
MRI angiography provides the highest resolution of the current angiographic methods and can often be performed without the use of contrast agents by modifying the pulse sequence to visualize aspects of the vessels such as blood flow. (wikipedia.org)
This less invasive form of angiography produces detailed images of your blood vessels without the use of catheters or X-rays. (mayoclinic.org)
