Delayed Contrast Enhanced MRI of Cartilage: Comparison of Ionic and Non-ionic Contrast Agents
Hypothesis: Delayed Gd(DTPA) enhanced MRI of cartilage (dGEMRIC) is a method designed to image the distribution of fixed charge density in cartilage, based on the premise that mobile ions will distribute in cartilage in relation to the concentration of the charged glycosoaminoglycan (GAG) molecules. The hypothesis to be tested here is whether the variation of T1 values post-Gd is a true reflect...
متن کاملAcetylcysteine and contrast agent-associated nephrotoxicity.
OBJECTIVES Prophylactic acetylcysteine along with hydration seems to be better than hydration alone in preventing the reduction in renal function induced by a contrast dye. BACKGROUND Contrast media can lead to acute renal failure that may occasionally require hemodialysis. METHODS One hundred eighty-three consecutive patients with impairment of renal function, undergoing coronary and/or pe...
متن کاملBrain parenchyma penetration by intrathecal ionic and nonionic contrast media.
Metrizamide, a nonionic water-soluble contrast medium, has been shown to penetrate normal brain when injected intrathecally. Recently it was suggested that the complications following intrathecal metrizamide are directly related to the cerebral concentration reached. Metrizamide, both in experimental animals and clinically, is regarded as less neurotoxic than equivalent iodine concentrations of...
متن کاملBronchial vasodilatory response to ionic and nonionic contrast media.
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...
متن کاملFree reactive oxygen species and nephrotoxicity of contrast agents.
BACKGROUND The nephrotoxicity induced by contrast media remains a serious clinical problem, and the underlying mechanism has not been completely understood. Experimental and clinical investigations suggest that reactive oxygen species (ROS) are critical determinants of radiocontrast nephropathy (RCN), and that antioxidants can prevent this damage. METHODS Cultured human proximal renal tubule ...
