DNA double-strand breaks of human peripheral blood lymphocyte induced by CT examination of oral and maxillofacial region

ConclusionsA CT examination of the head and neck region provides a high enough radiation dose to induce DNA double-strand breaks in cells in the peripheral blood. There was a linear correlation between the formation of DNA double-strand breaks and radiation doses after CT examination.Clinical relevanceIn addition to ensuring image quality, in a real clinical situation, the scanning area should be strictly administered, and repeated operations should be avoided to minimise the patient ’s radiation dose.
