PURPOSE To investigate changes in blood pressure during intracarotid injection of contrast
material. METHODS Two catheters were inserted into the ipsilateral common carotid artery …

PURPOSE To determine whether acute hypertension (HT) is a risk factor for damage to the
blood-brain barrier in carotid angiography with nonionic contrast media. METHODS …

This study was undertaken to investigate the role of contrast medium viscosity in blood-brain
barrier disruption after carotid angiography. Test solutions were injected into the carotid …

Changes of intracranial pressure during carotid angiography may be expected for several
reasons. BROMAN and OLSSON (1948) showed that intracarotid injection of contrast media …

A canine model was used to investigate the effects of intracarotid methylglucamine
iothalamate (280 mgI/ml) at different viscosities on the normal blood-brain barrier. To alter …

The use of radiographic contrast agents as indicators for the blood flow determination (10, a)
prompted this controlled experimental study. A precise knowledge of the various …

A rabbit model was used to assess the effects of intracarotid injections of ionic monomer
(meglumine iothalamate), non-ionic monomer (iohexol, iopromide), and non-ionic dimer …

Selective injection of contrast media into the canine common carotid artery results in
alterations in carotid flow, heart rate, and systemic arterial pressure. In this study the …

Relative patient discomfort resulting from carotid injections of three new low-osmolality
contrast agents was assessed in 78 patients. Omnipaque-300 (iohexol), Isovue-300 …

Changes in signal intensity of the brain at magnetic resonance (MR) imaging before and
after Gd-DTPA were used for in vivo quantification of injury to the blood-brain barrier (BBB) …
