Patients receiving high cumulative effective doses (CED) from recurrent computed tomography (CT) in a real-life setting are not well identified. Evaluation of causes and patient characteristics may help to define individuals potentially at risk radiation-induced secondary malignancies.Patients who received CED > 100 mSv CT scans during October 2012 April 2020 tertiary university center were identified with the radiological radiation dose monitoring system. The primary disease referral diagnosis, number exams, time period, age, BMI gender distribution 1000 patients highest analysed.3431 had more than mSv, which corresponded 2.75% all exam. From CED, mean exams per was 14.6, 257 (SD 98, range 177-1339). Mean age 63.9 years 10.6), male female ratio 3:2, 28.7 kg/m2 5.5). 728 (72.9%) cancer. leading diagnosis liver cirrhosis 197 103 transplantation. In cirrhosis, 750 indicated for follow-up disease, 662 clarification an acute clinical condition, 202 CT-guided stereotactic radiofrequency ablation.Recurrent cancer, transplantation lead critically CED.
