Gadolinium-based contrast agents for clinical magnetic resonance imaging are overall safe. However, the discovery of nephrogenic systemic fibrosis in patients with severe renal impairment and gadolinium deposition in patients receiving contrast have generated developments in contrast-free imaging of the vasculature, that is, noncontrast magnetic resonance angiography. This article presents an update on noncontrast magnetic resonance angiography techniques, with comparison to other imaging alternatives. Potential benefits and challenges to implementation, and evidence to date for various clinical applications are discussed.
用于临床磁共振成像的钆基造影剂总体上是安全的。然而,在严重肾功能损害的患者中发现了肾源性系统性纤维化,以及在接受造影的患者中发现了钆沉积,这促使人们开发了血管的无造影成像技术,即磁共振血管造影。本文介绍了非对比磁共振血管造影技术的最新进展,并与其他成像方法进行了比较。讨论了实施的潜在益处和挑战,以及目前各种临床应用的证据。
