Important kinetic features of any radiotracer include (1) the first-pass myocardial extraction,
which relates to the ability of a radiotracer to track flow in a linear fashion,(2) myocardial …

BACKGROUND AND PURPOSE: Although commonly acknowledged as paramount in
significance, the mechanics of cyanoacrylate polymerization remain poorly characterized and …

Currently, thallium-201 (201 Tl)-and technetium-99m (99m Tc)-labeled tracers are used
interchangeably for the detection of coronary artery disease, the assessment of myocardial …

The measurement of volumetric blood flow in small vessels in vitro and in vivo poses a
significant technological challenge. In this study, two pulsatile flow models were developed, one …

It is difficult to predict the adequacy of the collateral blood flow in patients who undergo
internal carotid artery occlusion. In order to address this difficulty, the authors have created a …

Objectives : The purpose of this study was to compare a selective A 2A adenosine receptor
agonist (regadenoson) with adenosine in clinically relevant canine models with regard to …

BACKGROUND Recent discussions on the relationship between intracranial aneurysm
diameter and rupture probability have focused on the presence of an apparent critical diameter …

The development of computer modeling technique of cerebral arteriovenous malformations
using circuit network analysis, validated with a previously developed animal model is …

Background It is difficult to predict which patients will tolerate occlusion of the internal
carotid artery. This difficulty arises primarily because of uncertainties in the prediction of the …

Purpose: To develop an accurate, fast, and robust algorithm for registering portal and
computed tomographic (CT) images for radiotherapy using a combination of sparse and dense …
