Shandong : Its role in magnetic resonance imaging

Gadolinium oxide is used as a contrast agent in magnetic resonance imaging (MRI), mainly to enhance the contrast of contrast materials through its unique physical and chemical properties. The gadolinium ions in gadolinium oxide can significantly affect the magnetic susceptibility of water molecules in surrounding tissues. During MRI, water molecules are the main imaging source, and changes in their magnetic susceptibility directly affect the intensity and contrast of imaging signals. Gadolinium oxide changes the magnetic susceptibility of water molecules, making the imaging difference between diseased tissue and normal tissue more significant, thereby improving the contrast of images. Gadolinium oxide often chelates with other molecules (such as DTPA, DOTA, etc.) to form stable complexes, which have low toxicity in vivo and can maintain stability for a long time. When these complexes are used as MRI contrast agents, they can more accurately locate the target tissue, improving imaging accuracy and contrast. Compared to traditional gadolinium-based chelates, nano gadolinium oxide particles have a lower risk of gadolinium ion leakage, larger specific surface area, and higher relaxation rate. A high relaxation rate means a stronger signal enhancement effect, which helps improve the contrast of MRI images. In addition, the targeted design of nanoparticles can enable them to reach diseased tissues more accurately, further improving imaging performance.
A new type of contrast agent, chitosan cross-linked folate-coated gadolinium oxide, is used for tumor-targeted magnetic resonance imaging. This new contrast agent combines the biocompatibility of chitosan, the tumor-targeting properties of folate, and the high relaxation rate of gadolinium oxide. It can improve the contrast of MRI images while achieving precise tumor localization. This contrast agent has broad application prospects in tumor diagnosis.
