Materials and methods. The analysis of publications was carried out on the data-bases Scopus, Web of Science, MedLine and RINC. Results. The variants of the use of CT of the head, chest, heart, abdominal and pelvic organs in multidisciplinary institutions with different methods of reducing the dose burden on patients have been analyzed. Conclusion. The factors used to reduce the dose for CT can be systematized in three main ways: 1) methods that depend on the attending physician, radiologist and CT staff; 2) parameters of the research protocol; 3) features of CT-devices and software. Considering the factors reducing the radiation dose of patients in support of the need for CT examination, choice of parameters of the CT protocol, CT devices and software allows to significantly re-duce the radiation burden on patients (by 10-78%) without compromising the quality of CT images. The development of methods to reduce the dose of irradiation of patients is extremely urgent, especially in screening, multiple CT studies and CT with contrast.

Keywords: review, radiation exposure, radiation reduction, dose reductions, computed tomography, CT-scanner, study protocol, software.
