OBJECTIVES We tested the hypothesis that intramyocardial injection of autologous bone
marrow (ABM) promotes collateral development in ischemic porcine myocardium. We also …

Background Perfusion imaging techniques intended to identify regional limitations in
coronary flow reserve in viable myocardium need to identify 2-fold differences in regional …

An ultrafast MR sequence was used to measure changes in signal intensity during the first
pass of intravascular contrast through the pulmonary circulation. From this, mean transit …

Precise measurements of regional myocardial blood flow heterogeneity had to be
developed before one could seek causation for the heterogeneity. Deposition techniques …

Objective: Blood supply of the lungs during total cardiopulmonary bypass (CPB) is limited to
flow through the bronchial arteries. This study was undertaken to assess the bronchial artery …

OBJECTIVES The present study examined the ability of real-time myocardial contrast
echocardiography (MCE) to delineate abnormalities produced by graded coronary stenoses …

A noninvasive magnetic resonance imaging (MRI) method to assess the distribution of
perfusion and metabolic demand (Q˙/V˙ o 2) in exercising human skeletal muscle is …

Background Both intermittent triggered and real-time myocardial contrast echocardiography
(MCE) have been proposed to detect impaired myocardial perfusion. We compared the …

Atherosclerotic carotid artery disease is an important stroke risk factor, and the risk of clinical
symptoms increases with the degree of stenosis. 1, 2 The role of statins in stroke prevention …

Seven fluorescent microsphere colors can be used in a single experiment to estimate
regional blood flow without correcting for spillover of emitted fluorescence. To extend the …
