BACKGROUND AND PURPOSE Two surgical trials established that carotid endarterectomy is beneficial to symptomatic patients who have a severe internal carotid artery (ICA) stenosis on angiograms. Duplex ultrasonography-derived hemodynamic parameters show a good correlation with angiography and are often used for detecting severe ICA stenoses. However, duplex performance is ultrasound machine and o...

Background: Variation in Renal restive index (RI) values measured using duplex Doppler ultrasonography has been shown to correlate with the degree of renal impairment in acute renal obstruction ,diabetic and hypertensive nephropathy patients. Aims and objectives: The primary objective of this study was to determine whether the intrarenal resistive index can be used as a predictor of progression...

BACKGROUND Previous studies have shown that a higher resistive index (RI) on renal duplex ultrasonography was related with renal progression and acute kidney injury, especially in patients with chronic kidney disease (CKD) using an angiotensin converting enzyme inhibitor (ACEI) or angiotensin receptor antagonist (ARB). We evaluated whether a RI value is a predictive factor for renal progression...

CONTEXT The process of diagnosing temporal arteritis remains controversial. Although temporal artery biopsy has long been the standard tool of evaluation, its poor sensitivity has prompted investigation of other methods to aid in diagnosis. Improved clinical evaluation and various imaging techniques have been suggested as ways to establish the diagnosis through noninvasive means and to improve ...
