Gadolinium-based contrast agents (GBCAs) are used in up to 35% of magnetic resonance imaging (MRI) examinations and are associated with an excellent safety profile. Nevertheless, two main issues have arisen in the last two decades: the risk of nephrogenic systemic fibrosis and the risk of gadolinium deposition and retention. As a first step, this article reviews the different categories of GBCAs available in neuroradiology, their issues, and provides updates regarding the use of these agents in routine daily practice. Recent advances in MRI technology, as well as the development of new MRI sequences, have made GBCA injection avoidable in many indications, especially in patients with chronic diseases when iterative MRIs are required and when essential diagnostic information can be obtained without contrast enhancement. These recent advances also lead to changes in recommended MRI protocols. Thus, in a second step, this review focuses on consensus concerning brain MRI protocols in 10 common situations (acute ischemic stroke, intracerebral hemorrhage, cerebral venous thrombosis, multiple sclerosis, chronic headache, intracranial infection, intra- and extra-axial brain tumors, vestibular schwannoma and pituitary adenoma). The latter allowing the standardization of practices in neuroradiology. Recommendations were also made concerning the use of GBCAs in neuroradiology, based on evidence in the literature and/or by consensus between the different coauthors.

基于d的造影剂（GBCA）最多可用于35％的磁共振成像（MRI）检查中，并具有出色的安全性。然而，在过去的二十年中，出现了两个主要问题：肾原性系统性纤维化的风险以及g沉积和retention留的风险。第一步，本文回顾了神经放射学中可用的GBCA的不同类别及其问题，并提供了有关在日常日常实践中使用这些药物的最新信息。MRI技术的最新进展以及新MRI序列的发展使得GBCA注射在许多适应症中都是可以避免的，尤其是在需要迭代MRI且无需增强造影剂即可获得基本诊断信息的慢性疾病患者中。这些最新进展也导致了推荐的MRI方案的变化。因此，在第二步中，本文的重点是在10种常见情况（急性缺血性中风，脑出血，脑静脉血栓形成，多发性硬化症，慢性头痛，颅内感染，轴内和轴外脑肿瘤，前庭神经鞘瘤和垂体腺瘤）。后者允许神经放射学实践的标准化。还根据文献证据和/或不同合著者之间的共识，提出了在神经放射学中使用GBCA的建议。脑静脉血栓形成，多发性硬化，慢性头痛，颅内感染，轴内和轴外脑瘤，前庭神经鞘瘤和垂体腺瘤）。后者允许神经放射学实践的标准化。还根据文献证据和/或不同合著者之间的共识，提出了在神经放射学中使用GBCA的建议。脑静脉血栓形成，多发性硬化，慢性头痛，颅内感染，轴内和轴外脑瘤，前庭神经鞘瘤和垂体腺瘤）。后者允许神经放射学实践的标准化。还根据文献证据和/或不同合著者之间的共识，提出了在神经放射学中使用GBCA的建议。
