A randomized double-blind crossover study using Omnipaque 350 mg l/ml (iohexol) and Hexabrix 320 mg l/ml (ioxaglate) in 53 patients undergoing intravenous digital subtraction angiography of the carotid arteries revealed no significant differences in image quality. Some differences were found in subjective side effects that favored Omnipaque. Nausea was reported in four patients after injection ...

Objective: To investigate the liver-injury of the SD rats in autologus orthotopic liver transplatation using Meglumine Diatrizoate and Omnipaque. Methods: The portal veins of 60 healthy SD rats were perfused to set up orthotopic liver autotransplatation models. Then the external drainages of rats’ bile duct were built up by bile duct cannula. The ALT and AST in blood serum were detected 24h and...

Iodine-based agents such as Isovue and Omnipaque. These contrast agents are used in humans primarily for visualizing vasculature and urinary tract, but may be useful for imaging other organs as well. They are small molecules, rapidly excreted through the kidneys, providing intense contrast in the kidneys and bladder. They can be dosed IP as a way to create contrast outside of organs such as the...

Omnipaque, 300 mg l/ml, was compared with Amipaque, 300 mg l/ml, for cerebral angiography. Twelve patients were included in a randomized, double-blind, crossover study. Twenty comparisons were made in the external carotid and 21 in the vertebral artery, Both contrast media caused no or minor changes in blood pressure and heart rate. Good to excellent radiographic visualization of the cerebral a...

Relative patient discomfort resulting from carotid injections of three new low-osmolality contrast agents was assessed in 78 patients. Omnipaque-300 (iohexol), Isovue-300 (iopamidol), and hexabrix (ioxaglate) were sequentially injected into both common carotid arteries of each patient. Patients were asked to rank the relative intensities of the three injections on each side. Mean patient rankin...

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). However, the precise mechanism for this increase in Qbr is unknown. In this study we examined the effect of bronchial arterial injection of conve...

Orally administered hypertonic contrast media draw fluid into the intestines, which, if severe enough, could result in hypovolemia. Likewise, in infants and young children, the occurrence of diarrhea may result in hypovolemia. Plasma fluid loss may be sufficient to cause a shock-like state, which, if untreated, could be dangerous. This is especially pertinent to the elderly, cachectic patients ...

Omnipaque (iohexol) 350mg/ ml. 20ml at 5ml/sec followed by saline flush. No Premedication was given before the procedure. Discrete, coronary aneurysms (defined as segmental dilation between 1.50to 2.0-fold larger than maximal normal diameter of the respective vessel [4]) was documented in the distal Left main coronary artery (LMCA), proximal Left anterior descending artery (LAD) and proximal Ri...
