Also, unlike ultrasonography of deep venous thrombosis, the procedure focuses mainly on superficial veins. Also, unlike the arterial ultrasound examination, blood velocity in veins has no diagnostic meaning. Veins are a draining system similar to a low pressure hydraulic system, with a laminar flow and a low velocity.
Unlike arterial ultrasonography, venous ultrasonography is carried out with the probe in a transversal position, (perpendicular to the vein axis), displaying cross-sections of the veins. [4] All collateral veins are better detected this way, including perforator veins , but of most importance is the detection of venous thrombosis .
Ultrasound methods including duplex and color flow Doppler can be used to further characterize the clot [117] and Doppler ultrasound is especially helpful in the non-compressible iliac veins. [ 119 ] CT scan venography , MRI venography, or a non-contrast MRI are also diagnostic possibilities. [ 120 ]
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.

Ultrasound is essential to the procedures of ultrasound-guided sclerotherapy and endovenous laser treatment for the non-surgical treatment of varicose veins. [17] Ultrasound-guided sclerotherapy techniques are also used to treat ovarian endometriomas , especially for patients who are pregnant.
Young Reno adults paying more in mortgage than rest of U.S. on average. The median mortgage loan for Reno's under-25 homebuyers was $330,000, according to the study.
