has excellent sensitivity and specificity of 97% and 94% respectively, with positive and negative predictive values of 97% and 98% respectively for proximal DVT.
In case of embolic stroke, the patient should undergo imaging of the carotid vessels by duplex ultrasonography
, CT angiography, MRI angiography, or catheter angiography.
In his algorithm, patients at highest risk should have angiography, while those with moderate risk should have captopril renography or duplex ultrasonography
(depending on the expertise of the institution).
gives the physician the ability to non-invasively measure the velocity of blood flow, and in a properly treated artery, the velocity markedly decreases.
on day 6 showed left internal jugular vein thrombosis.
Comparison of duplex ultrasonography
and venography in the diagnosis of deep venous thrombosis.
A PICC-associated DVT was defined as a symptomatic event prompting a duplex ultrasonography
study which confirmed venous thrombosis.
Carotid duplex ultrasonography
at that time revealed a 70 to 80% stenosis of the right internal carotid artery (figure).
At present, a common diagnostic approach is to perform an initial screening test with duplex ultrasonography
, followed by an angiogram for surgical planning.

Physical examination of the right testicle revealed a hydrocele with an otherwise normal appearing testis, which was confirmed with Duplex ultrasonography
