Dosis acumulada de radiación en tomografía computarizada en pacientes atendidos en el Hospital Vicente Corral Moscoso, Cuenca, año 2019

Abstract

Background: computerized axial tomography is a diagnostic imaging study widely used in recent years due to its high specificity, however, exposure to ionizing radiation has generated controversy among medical personnel due to possible damage or mutations that it could cause in the tissue. Objective: to determine the radiation dose in computed tomography in patients treated at the Vicente Corral Moscoso Hospital during the year 2019. Materials and methods: this is a retrospective cross-sectional cohort study. 296 clinical records of patients who met the inclusion criteria were included. The information was analyzed using the statistical program SPSS version 15.0, applying descriptive statistics. Results: 72% of patients underwent simple tomographies and 49.3% contrasted. The most studied anatomical regions were the head and neck structures with 65.9%. In 90.9% of the cases that underwent simple and contrast CT, the effective dose of radiation was low (0-50 mSV); in the people in whom only a simple CT was performed, 4.4% were categorized as medium risk and 2.4% high; and in participants who underwent contrast-enhanced CT, 2.7% and 2% were considered medium and high risk respectively. According to the accumulated radiation, 81.4% presented low risk; in simple CT 8.4% medium risk in contrast to 7.4% in contrast-enhanced CT and 4.7% versus 3.7% high risk in simple and contrast-enhanced CT respectively.
