MRI contrast for the precise diagnosis of tumor with target specificity of less than 1 nM and method for preparing thereof

摘要

TECHNICAL FIELD The present invention relates to a contrast agent for a magnetic resonance imaging diagnostic for a fine tumor having a target selectivity of less than 1 nmol and a method for producing the contrast agent. The magnetic nanoparticle, which is a contrast agent for T2-weighted MR imaging, The present invention provides an effect that can be used for the precise diagnosis of breast cancer and metastatic cancer expressing the cancer-specific biomarker.
