We measured sensitivity, positive predictive value, and free-response receiver operating characteristic (FROC) of 20 radiologists detecting subsegmental-sized pulmonary emboli in a porcine model using either contrast-enhanced computed tomography (CT)

The purpose of this study was to identify perfusion defects of the lung using computed tomography (CT). A balloon catheter was placed in a lobar pulmonary artery of six anesthetized, ventilated, juvenile pigs to simulate occlusive segmental embolus.

Rationale and Objectives The purpose of this study was to compare gadolinium-enhanced magnetic resonance (MR) angiography with contrast material–enhanced computed tomography (CT) for the detection of small (4–5-mm) pulmonary emboli (PE), with a m

Rationale and Objectives. The authors performed this study to determine if there were differences in vascular caliber measured on angiograms obtained with the injection protocol used for spiral computed tomography (CT) versus that used for pulmonary

Endogenous nitric oxide (NO) influences acetylcholine-induced bronchovascular dilation in sheep and is a mediator of the airway smooth muscle inhibitory nonadrenergic, noncholinergic neural response in several species. This study was designed to dete

The bronchial vasculature is the systemic arterial blood supply to the lung. Although small relative to the pulmonary blood flow, the bronchial vasculature serves important functions and is modified in a variety of pulmonary and airway diseases. Cong

It has recently been shown that bronchial arterial injection of conventional contrast medium causes a significant increase in bronchial blood flow (Qbr) and that this response is partially attenuated after infusion of N omega-nitro-L-arginine (L-NNA)

Contrast agents have been shown to produce vasodilatory responses in several vascular beds. To our knowledge, however, their effect on the bronchial vasculature has not been examined. Clinically, contrast-induced bronchial vasodilation could potentia

To test whether endogenous endothelial nitric oxide (NO) influences baseline bronchial vascular tone and mediates acetylcholine (ACh)-induced bronchial vascular dilation and/or modulates bronchoconstriction in ovine airways, we studied anesthetized v

It is generally assumed that when pulmonary vascular pressures are normal the pulmonary contribution to central airway blood flow (Qp) is negligible compared with systemic blood flow (Qs). However, it has been suggested in recent reports that a subst
