Ultrasmall iron oxide nanoparticles and gadolinium-based contrast agents in magnetic resonance imaging: a systematic review and meta-analysis

ConclusionStatistical studies confirmed that US-IO nanoparticles with a size of less than 5  nm in positive contrast MRI had higher r1 and approximately similar r2/r1 in different studies, as well as better than the Dotarem in increasing signal intensity. Therefore, US-IO NPs could be a hopeful candidate for use as T1-weighted contrast agents in MRI.
