The present invention relates to [
18
F]-fluciclatide radiopharmaceutical compositions, which are stabilised with a radioprotectant. Also described are methods for the preparation of the radiopharmaceutical compositions, including automated synthesizer methods and cassettes for use in such methods. The invention also includes methods of imaging the mammalian body using the radiopharmaceutical compositions.
The present invention relates to a method of purification of [
18
F]-fluciclatide via solid phase extraction (SPE). The method is amenable to automation, and is suitable for use in conjunction with automated synthesizer apparatus—especially cassette-based synthesizers. Also provided are cassettes for carrying out the purification method.
