DEFINITION

Classification: 424/9.4

X-Ray contrast imaging agent (e.g., computed tomography, angiography, etc.):

(under subclass 9.1) Subject matter wherein a compound or composition is adapted for use as an in vivo X-ray contrast imaging agent in methods such as computed tomography, angiography, etc.

(1) Note. X-ray contrast imaging is based on the fact that the agent renders part of an animal body opaque (degree of opacity may vary) to X-rays.

(2) Note. An example of a compound provided for herein is: [figure]
