objective: duplex ultrasonography is a non-invasive, non-expensive screening test for carotid disease. intima media thickness (imt) is appropriate for atherosclerosis process diagnosis. leukoaraisis (la) increase the risk of cerebrovascular accident (cva). la patients need preventive medication for cva. imt is a non-invasive diagnostic and prognostic test in la. the aim of this study was evalua...

conclusions neither of studied variables was perfect to differentiate cirrhotic patients with and without evs. endoscopy is still the gold standard diagnostic method for diagnosing esophageal varices in patients with cirrhosis. it seems that some of the splenoportal doppler indices are promising, but more research and evaluation is necessary. results forty-four patients were male and 22 female....

Background and Purpose We compared two-dimensional time-of-flight magnetic resonance angiography (MRA) and duplex ultrasonography with arteriography for the detection of 70% to 99% stenoses at the carotid artery bifurcation (ie, surgical disease according to findings of the North American Carotid Endarterectomy Trial). Methods Three blinded readers independently measured stenoses on MRA in 73 v...

OBJECTIVES To determine sensitivity, specificity and other operating characteristics of bedside three-point compression ultrasonography performed in emergency department by emergency physicians in comparison with duplex ultrasonography. METHODS The cross-sectional study at Rasoul-e-Akram Hospital in Tehran, Iran, prospectively evaluated 81 suspected patients of lower extremity deep vein throm...

BACKGROUND Temporal artery (TA) biopsy is the current standard for diagnosing temporal arteritis, but has limited sensitivity. Colour duplex ultrasonography is a newer, non-invasive method of diagnosing temporal arteritis. METHODS A systematic review was performed of trials comparing TA biopsy with duplex ultrasonography. Duplex results (halo sign, stenosis or vessel occlusion) were compared ...

Two patients had multiple embolic infarctions in the middle cerebral artery territory. Free-floating thrombi adherent to plaques were detected in the common carotid artery near the bifurcation using duplex ultrasonography. Further strokes did not occur under anticoagulation. The free-floating thrombi disappeared on follow-up sonography. Carotid duplex ultrasonography is useful for recognizing f...
