Background: Computed tomography is the radiological study with the greatest sensitivity in the diagnostic field, the increase in its use creates awareness of the risks produced, generating concerns that guide research to evaluate the dose levels given in each exposure. Objective: To describe the Dose Index in Computed Tomography of the chest performed at the Guillermo Almenara Irigoyen National Hospital between March and August 2020. Materials and Methods: An observational, descriptive and cross-sectional study was carried out with the CTDI and DLP data from the PHILLIPS tomograph, the data were simulated with the CT-Expo V2.3 software, both data were compared and recorded in tables and bar graphs using Microsoft Office Excel 2015. Results: Out of 395 chest CT scans, the most exposed population was male (55%) over 59 years old (52%), the average values were: Weight: 84 kg, Height: 1.66 cm. For the Dose Index, the average values were: PHILLIPS tomograph: 9.58 mGy, Ct-Expo Software: 9.5 mGy. For the Product Dose Length, the average values were: PHILLIPS tomograph: 466.2 mGy*cm, Ct-Expo Software: 471.69 mGy*cm. For the effective dose, the value obtained from the simulator was 7.84 mSv Conclusion: The CT-Expo Simulator Software is a valuable tool, as it estimates the radiation dose of a population with standard characteristics, indicating a better dosimetric accuracy of the chest.
