| Abstract: |
| A contrast agent (or contrast medium) is a substance used to increase the contrast of structures or fluid within the body in medical imaging. When injected into the body, contrast agents enhance and improve the quality of the medical image. This allows the radiologist to more accurately report on how your body is working and whether there is any disease or abnormality present. Gadolinium oxide is a paramagnetic element that shortens T1 and therefore it has the ability to enhance the contrast of the MRI image. Gold on the other hand has a high atomic number and it can function as a contrast agent in radiography (X-Ray). Herein, gold-coated gadolinium oxide nanostructures were synthesized to use as multimodal contrast agents. |
