  • at least a first energy source adapted to supply X-ray energy or gamma ray energy to tissue in the vicinity of a site along a path of potential extravasation of fluid from a blood vessel into which fluid is injected;

    at least a first sensor to measure a signal resulting from the energy supplied to the tissue by the first energy source, the signal being proportional to the X-ray energy or gamma ray energy transformed, reflected, scattered or absorbed by an extravasated fluid present in the vicinity of the site; and

    an indicator to provide an indication of the occurrence of extravasation.
