ABSTRACT 

In medical imaging, contrast agents play an important role in refining the clarity and contrast of a body part. Higher clarity and contrast allows the physician to clearly differentiate between the body structure and nearby tissue. This allows for accurate examination and diagnosis of any abnormality in the body part. Contrast agents are used for medical scans such as the Positron Emission Tomography (PET) scan, a frequently used diagnostic method in modern clinical practice that does not use damaging ionizing radiation. Through electrochemical techniques, researchers have studied the possibility of using aqueous nanoparticles as contrast agents.
