composition, nanoscale particle for use in x-ray imaging and method for treating a condition or disease associated with undesirable cell growth in an individual in need thereof
The present invention relates to a method and nano-sized particles for image guided radiotherapy (IGRT) of a target tissue. More specifically, the invention relates to nano-sized particles comprising X-ray-imaging contrast agents in solid form with the ability to block x-rays, allowing for simultaneous or integrated external beam radiotherapy and imaging, e.g., using computed tomography (CT).
