Gadolinium-based contrast agents are used in magnetic resonance imaging (MRI) to enhance the quality of the images by altering the magnetic properties of water molecules in the body. These agents are particularly useful in detecting and characterizing abnormalities in tissues, such as tumors, inflammation, and blood vessel diseases, by improving the contrast between normal and abnormal tissues.

Gadolinium-based Contrast

Gadolinium-based contrast agents (GBCAs) are used in MRI to enhance the visibility of internal structures, but they carry a risk of nephrogenic systemic fibrosis in patients with impaired kidney function. Recent developments focus on reducing gadolinium retention in the body to improve patient safety.

Magnetic Resonance Imaging (MRI) is a non-invasive imaging technique that uses strong magnetic fields and radio waves to generate detailed images of the organs and tissues in the body. It is widely used in medical diagnosis and research due to its ability to provide high-resolution images without exposure to ionizing radiation.

Characterizing abnormalities in tissues

Tumors are abnormal growths of tissue that can be benign or malignant, with the potential to invade surrounding tissues and spread to other parts of the body. Understanding the nature of tumors is crucial for diagnosis, treatment, and management of cancer and other related diseases.

Tumors

Inflammation is the body's complex biological response to harmful stimuli, such as pathogens, damaged cells, or irritants, and is a protective attempt to remove the injurious stimuli and initiate the healing process. While acute inflammation is a vital part of the immune response, chronic inflammation can contribute to various diseases, including arthritis, cardiovascular diseases, and certain cancers.
