佳迪显TM钆特酸葡胺注射液产品介绍 钆特酸葡胺注射液 离子型、大环、非特异性钆对比剂 浓度：0.5 mmol/mL 经典大环螯合结构 Gd-DOTA 钆特酸葡胺适用于全身各部增强应用 The low incidence of adverse reactions (1%) and the absence of serious adverse reactions reported during the survey period showed that Gd-DOTA was very well tolerated. In conclusion, the use of Gd-DOTA as an MRI-enhancing contrast medium in the clinical practice setting appears to be safe and effective. 观察共3444例患者，包括儿童(1个月~14岁) 41例使用钆特酸葡胺的MR增强的安全性和有效性。 钆特酸葡胺安全性高，也适用于婴幼儿 Gadoteric acid is a well-tolerated MRI contrast medium in patients with and without risk factors that is associated with a low rate of adverse events and good or excellent image quality in most patients 观察共84000例患者，不良反应事件发生率(0.34%)，仅8例发生重度不良反应，的MR增强的安全性和有效性。 钆特酸葡胺安全性高，也适用于婴幼儿 Eur J Radiol. 2012 May;81(5):885-90. doi: 10.1016/j.ejrad.2011.04.022.

Paramagnetic contrast agents currently on the market can be classified as ionic or non-ionic and as linear or macrocyclic structures. Magnevist? e Dotarem? are ionic compounds. Their solution needs to be salified (i.e. with meglumine) in order to neutralize the positive charge of gadolinium. ProHance? e Omniscan? are non-ionic compounds, and therefore they do not need to be salified. Their solutions
