NCT05045872

Brief Summary

Conventional contrast-enhanced magnetic resonance imaging is typically performed with extracellular gadolinium chelates, which is often limited in patients with CKD owing to the risk of nephrogenic systemic fibrosis. Ferumoxytol, a novel contrast medium, can be used as an "off-label" contrast agent for magnetic resonance imaging. During the last decade, ferumoxytol has gained appeal as an MRI contrast agent in patients with estimated glomerular filtration rates \<30mL/min and there are reports in the literature for its safe use and utility in both adult and pediatric patients with CKD. The study is designed to evaluate the diagnostic performance of ferumoxytol-enhanced magnetic resonance imaging in patients suspected of renal artery stenosis, investigate the correlation between renal cortical T2\*(T2\*=1/R2\*) and renal function, and develop an automatic algorithms for renal vessel segmentation.

Study Arms (1)

ferumoxytol-enhanced renal magnetic resonance imaging

EXPERIMENTAL

Patients will receive ferumoxytol-enhanced renal magnetic resonance imaging before renal angiography. Ferumoxytol (510 mg/17mL; Chia Tai Tianqing Pharmaceutical Group Co Ltd, Nanjing, China) will be diluted at 1:4 (v/v) and intravenously infused into the antecubital vein at a dose of 3 mg/kg with an infusion speed of 0.07 mL/s.

Drug: domestic polysaccharide superparamagnetic iron oxide nanoparticle

Interventions

Patients will receive contrast-enhanced renal magnetic resonance imaging with polysaccharide superparamagnetic iron oxide nanoparticle before renal angiography. Patients received intravenous polysaccharide superparamagnetic iron oxide nanoparticle before magnetic resonance imaging.

Also known as: ferumoxytol
