Background Noninvasive direct flow measurement from digital subtraction angiography (DSA) is challenging in brain arteriovenous malformations (BAVMs). We devised a method to estimate the blood volume flow rate of BAVM nidus using DSA, and assessed it

The purpose of our study was to elucidate the impact of brain arteriovenous malformation (BAVM) flow and wall shear stress (WSS) on angioarchitecture and to evaluate their association with hemorrhagic presentations.Forty-one patients with BAVMs were

Digital subtraction angiography (DSA) is the gold standard for diagnosing vascular diseases. Much attention had been attracted on estimating blood flow velocity from DSA data, and many techniques to compute the mean flow velocity had been proposed. I

Objective. Four-dimensional (4D) digital subtraction angiography (DSA) offers a method for evaluating hemodynamics. It is, however, unclear how the delivered contrast medium interacts with the physiological blood flow, and how hemodynamic information

Time-resolved 3D DSA, also known as 4D DSA, enables inspection of vasculature from any desired angle and time frame. The 4D DSA encompass both time resolved hemodynamics and 3D vascular architecture, and theoretically provides more insights

Background: The efficacy of both quantitative digital subtraction angiography (QDSA) and flat-detector computed tomography perfusion (FD-CTP) is equivalent to that of magnetic resonance perfusion (MRP) in assessing perfusion deficits in carotid steno
