Research Article: Preclinical Evaluation of a Protein-Based Nanoscale Contrast Agent for MR Angiography at an Ultralow Dose
Introduction:
Magnetic contrast agents (CAs) are routinely used in –% of all clinical MR examinations. The overwhelming majority of the commercially available CAs for magnetic resonance imaging (MRI) are Gd-based chelators due to their signal brightening effect, high signal-to-noise ratio (SNR) and absence of magnetic susceptibility artifacts. It has been accepted that Gd CAs could be rapidly excreted after intravenous injection and are thus safe for human use. Unfortunately, recent decades have witnessed increasing reports of…
