Abstract

In recent years, the development of medical technologies leveraging nanomedicine has witnessed remarkable progress, particularly in areas such as targeted drug delivery, controlled drug release, tissue engineering, and diagnostics. This review explores the transformative impact of nanotechnology on medical imaging, focusing on developing novel contrast agents. Diagnostic imaging techniques, including Positron Emission Tomography (PET), Computed Tomography, and Magnetic Resonance Imaging, have become indispensable tools in modern healthcare. Contrast agents play an important role in enhancing the sensitivity of these imaging modalities, enabling the detection of previously undetectable anomalies. Nanotechnology offers unprecedented opportunities to revolutionize contrast agent design, leading to improved imaging modalities and diagnostic accuracy. Due to their high X-ray attenuation coefficients, metal-based inorganic nanoparticles, such as gold, bismuth, and lanthanide-based nanomaterials, exhibit significant potential as CT contrast agents. Furthermore, the pharmacokinetic properties and drug metabolism profiles of these nanomaterials are critical in ensuring their safety, efficacy, and optimal performance in clinical applications. Moreover, nanomaterials with integrated diagnostic and therapeutic capabilities are emerging as promising candidates for real-time disease detection and image-guided treatment. This review highlights the properties of nanomaterials that make them suitable for use as contrast agents. It discusses the challenges and opportunities in developing multifunctional nanomaterials for medical and diagnostic purposes. Overall, nanotechnology-enabled contrast agents have the potential to redefine the landscape of medical imaging, paving the way for more precise diagnosis and personalized treatment strategies.
