Web1 de jun. de 1997 · There was no relationship between peak systolic velocity and resistive index or time between transplantation and US. High peak systolic velocity was associated with a pronounced vessel curvature. CONCLUSION: The normal range of peak systolic velocity in the transplanted renal artery has considerable variability. Web11 de jun. de 2024 · Doppler ultrasound (US) is a well-established and useful technique for evaluating the renovascular system and associated pathologic conditions. As with other US examinations, advantages include its noninvasive nature, relatively low-costs, and generally well-tolerated. However, the technique is highly operator-dependent and can be time … bizanzzio stretchy top on lid

WebThe optimal cut point for the highest renal artery velocity was 300 cm/s and for acceleration time, 0.1 second. The sensitivity and specificity using these cut points were 84% and 83%, respectively, for highest renal artery velocity, 91% and 78% for acceleration time, and 90% and 83% for spectral broadening. Web(1) Background: Cognitive impairment (CI) is common in chronic kidney disease (CKD) and patients treated with hemodialysis.
