A High-Performance Ytterbium-Basei Nanopartkulate Contrast Agent for In Vivo X-Ray Computed Tomography Imaging

摘要

X-ray computed tomography (CT) is one of the most widely used imaging procedures in diagnostic medicine due to its many advantages that include cost effectiveness, deep tissue penetration, and high resolution. Currently, small iodi-nated molecules are routinely used for in vivo contrast enhancement in the clinical setting. lodinated molecules can effectively absorb X-rays but suffer from short circulation lifetime and potential renal toxicity.
