  • Quality control devices and methods for radiopharmaceuticals
    Patent number: 9291606
    Abstract: A quality control (“QC”) system for PET or SPECT radiopharmaceuticals is disclosed that contains a disposable, no-leakage, self-contained QC cassette, which interfaces with the QC system. The QC system may include a shield that substantially surrounds the cassette such that the area and the cassette are both shielded. The QC cassette may contain shielding also. The QC cassette contains components for conducting one or more QC tests. These components include sensor and devices for performing various QC tests on radiopharmaceuticals. The QC system may contain a number of sub-systems and devices for supporting the QC tests. The QC system may produce a QC report containing the test results.

  • Process for preparing contrast agents
    Patent number: 6509004
    Abstract: The invention provides a process for the preparation of a pharmaceutical composition comprising an aqueous dispersion of gas-containing vesicles the membranes whereof comprise an amphiphilic membrane-forming material, said process comprising: (i) generating a liquid dispersion of gas-containing vesicles from a mixture comprising an amphiphilic membrane forming material; (ii) lyophilizing a liquid dispersion of said gas-containing vesicles; (iii) reconstituting the lyophilized product of step (ii) with a sterile aqueous liquid to produce an aqueous dispersion of gas-containing vesicles; and (iv) treating the aqueous dispersion product of step (iii) or the lyophilized product of step (ii) to produce a substantially aggregate-free sterile aqueous dispersion of gas-containing vesicles.
