Multifunctional theranostic nanomaterials as magnetic resonance imaging contrasting agents and imaging

Magnetic resonance imaging is in practice to visualize malignancies and diagnose diseases. CAs are important molecules that aid in enhancing the images of the lesions through magnetic resonance imaging. “Theranostics” is a new concept that has become widely popular and aims at diagnosis and treatment of diseases, having dual functioning. To achieve this, nanoparticles (NPs) are bound to the contrasting agents (CA), as they are nano-sized and reach the target sites easily and efficiently. In this chapter, we will be talking about the application of theranostic NPs in various pathological conditions like cancer, cardiovascular, inflammatory, infectious, and central nervous system-related diseases along with diabetes, thrombosis, etc. Thus, theranostic agents have been demonstrated to successfully target the site of action with improved T1 and T2 images, which will help physicians to improve their therapeutic approach.
