Assessment of the dynamics of pulmonary nodules using low-dose computed tomography

Abstract

Relevance. Screening for lung cancer and pulmonary nodules using low-dose computed tomography is associated with a decrease in lung cancer mortality. Comparative analysis of lung nodules and micronodules in cancer patients using this technique allows to reduce the total exposure dose per patient. Objective of the study. To determine the level of radiation exposure during repeated examinations in cancer patients and automatically measure and compare pulmonary parenchymal nodules using the licensed Vidar-lung nodules program. Materials and methods. The studies are conducted at the National Center of Oncology in Baku, in the CT and MRI department. The Siemens Definition Flash device is used with the Lung Low Dose and Ultra Low Dose protocols. Retrospectively, studies were taken from 30 patients who underwent low-dose CT. Results and discussion. Of the 30 patients, 20 were men and 10 were women. The average age was 35 years. The maximum radiation dose for one examination is no more than 0.6 mSv. The same doses were used in subsequent control examinations. Conclusion. Low-dose chest computed tomography allows to reduce the accumulated exposure dose in cancer patients with detected pulmonary nodules undergoing a repeated control examination according to the indications and recommendations of the oncologist.
