Background. Correct positioning of the patient in the CT gantry, adjustment of the technical scanning parameters to the anatomical characteristics of the patient, use of mA modulated by AEC, to the detriment of a fixed value, automatic selection of kV, choice of noise index depending on the indication clinical and concomitant examination of the abdomen and pelvis contribute to the personalization of imaging examinations with the optimization of irradiation doses in the dynamic evaluation of the treatment of cancer patients. Objective of the study. To evaluate the technical peculiarities of scanning imaging scans by computed tomography in patients with neoplasms of the abdomen and pelvis to optimize the effective dose. Material and Methods. The study included 52 patients, repeatedly investigated by computed tomography in 2013-2019, a total of 127 examinations, of which 120 prospective examinations and 7 retrospective examinations, aged between 25 and 77 years, with primary tumors of abdomen and pelvis. Results. Specific technical and oncological radiological indicators, scanning time, scanning step, post-processing programs were analyzed. The results of the study show that the concomitant examination of the abdomen and pelvis requires continuous scanning, which helps to reduce the scanning time while avoiding overlapping doses - as a result we obtained a 30% lower effective dose. |
