A considerable dose reduction without loss of diagnostic information is achievable in dental CT. As radiation exposure of the presented low-dose protocol is expected to be in the same range as DVT, low-dose dental CT might be superior to DVT, because CT can be used to evaluate soft tissues as well.

A considerable dose reduction without loss of diagnostic information is achievable in dental CT. Dose-reducing examination protocols like the one presented may further expand the use of preoperative dental CT.

In the scope of cardiovascular brachytherapy beta- as well as gamma-ray emitting radionuclides are used. The handling of radioactive sources is within the range of the radiation protection regulations (Strahlenschutzverordnung [StrlSch V]). According to EU guidelines an amendment of the StrlSch V is required by May 2000. The connected reduction of dose limits now should already be taken into consideration when planning irradiation facilities, likewise in cardiovascular brachytherapy. Temporary regulations for equipment that was already in operation before May 2000 are not planned in the new StrlSch V.
