“…This image can allow one to identify abnormal intraluminal and perivascular structures (thrombus or tumour). However, a fresh thrombus may not give reflection as well as blood itself [6].…”

“…The blood flow in most blood vessels is laminar, with the blood moving in thin concentric layers or lamellae. The central layers flow the fastest, whereas frictional forces cause energy loss and slowing of the layers near the vessel walls [6].…”

“…On the other hand, each of the arteries chosen is important for its diagnostic value, for example, aortic thrombosis in cats is difficult to see without the use of Doppler imaging. Also, abnormal flow patterns in the celiac artery are associated with liver neoplasia in dogs (Finn Bodner and Hudson 1998). Doppler spectral patterns of the cranial mesenteric artery give a good clue of the gastrointestinal physiologic state of a patient (Finn Bodner and Hudson 1998).…”

“…A técnica Doppler pulsado é considerada método simples, acessível e não invasivo que permite avaliar a hemodinâ-mica renal por meio das mensurações da velocidade má-xima ou de pico sistólico (VPS), a velocidade mínima ou diastólica final (VDF), a velocidade média (Vm) durante o ciclo cardíaco (Finn-Bodner & Hudson 1998, Szatmári et al 2001, Novellas et al 2007a) e pelo cálculo dos índices hemodinâmicos de resistividade (IR) (Pourcelot 1974) e de pulsatilidade (IP) (Gosling et al 1974). O IR, também denominado índice de Pourcelot e o IP quando obtidos nas artérias intrarrenais (arqueadas e interlobares) refletem a impedância vascular renal (Rivers et al 1997b Embora o IR renal seja resultado da complexa interação entre complacência arterial, resistência vascular periférica e pulsatilidade arterial (Schnell & Darmon 2012), para fins clínicos e investigativos, é geralmente aceito como uma expressão da resistência a passagem do fluxo sanguíneo arterial (Morrow et al 1996, Novellas et al 2007a.…”
