Medical imaging is one of the key tools used for examining and diagnosing patients. A variety of technologies for creating both 2- and 3-dimensional images of the body are routinely used in the clinic today. Some of these include X-ray Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and nuclear imaging techniques such as Positron Emission Tomography (PET).
Each of these techniques have both advantages and disadvantages. For example, CT and MRI are widely used for anatomical imaging because of the ability to produce high resolution images. However, these techniques have relatively low sensitivity compared to nuclear imaging techniques such as PET, which may be used to trace drug molecules as they circulate through the body.
Recent advances in technology have allowed simultaneous imaging using multiple imaging modalities. Clinics have begun adopting simultaneous PET/CT and PET/MRI for applications in fields such as oncology, cardiology and neurology.
As medical imaging technology continues to advance, there is a need to develop new contrast agents capable of multimodal imaging. Building on our previous work with gadonanotubes, we aim to develop new multimodal imaging agents based on the ultrashort carbon nanotube platform.
