The reflected ultrasound is received by the probe, transformed into an electric impulse as voltage, and sent to the engine for signal processing and conversion to an image on the screen. The depth reached by the ultrasound beam is dependent on the frequency of the probe used. The higher the frequency, the lesser the depth reached. [9]
Coronal plane, seen from medial side of lower leg, showing thrombosis of the fibular veins, with hyperechoic content and only marginal blood flow. Ultrasonography in suspected deep vein thrombosis focuses primarily on the femoral vein and the popliteal vein , because thrombi in these veins are associated with the greatest risk of harmful ...
Ultrasound duplex scanning can provide additional information that may guide therapeutic decisions. The location and severity of arterial narrowings and occlusions can be identified. The vascular sonographer can map disease in lower-extremity segments with great accuracy, though duplex scanning is more time-consuming than other lower-extremity ...
The lateral cutaneous nerve of the thigh can be studied using ultrasound. [1] A patient lies on a bed facing upwards (supine). [3] The ultrasound probe is moved along the length of the nerve, often starting from near the ASIS. [3] The nerve is easier to see over the sartorius muscle than in other subcutaneous tissue, as there is greater ...
Ultrasound is indicated if superficial phlebitis involves or extends into the proximal one-third of the medial thigh, there is evidence for clinical extension of phlebitis, lower extremity swelling is greater than would be expected from a superficial phlebitis alone or diagnosis of superficial thrombophlebitis in question.
A lower limbs venous ultrasonography may refer to: Ultrasonography of chronic insufficiency of the legs; Ultrasonography of deep venous thrombosis
Top image shows the contralateral normal side, and lower image shows a retracted muscle, with a hematoma filling out the proximal space. Panoramic ultrasonography is the digital stitching of multiple ultrasound images into a broader one. [100] It can display an entire abnormality and show its relationship to nearby structures on a single image ...
Perforator veins exist along the length of the lower limb, in greater number in the leg (anatomical ref to below knee) than in the thigh. Some veins are named after the physician who first described them: Dodd's perforator at the inferior 1/3 of the thigh; Boyd's perforator at the knee level
