Various nano-sized materials are developed as novel CT contrast agents to overcome the limitations of current iodinated agents. These novel agents using heavy atoms such as gold, tantalum, lanthanides, and bismuth provide more efficient X-ray contrast effects, and their long-circulation time and facile surface modification allow a variety of applications including targeted imaging, angiography, multimodal imaging, and simultaneous diagnosis and therapy.
