The first experience of using a hybrid dual-energy CT (DECT) scans with an inert gas xenon in patients with lung pathology

Routine diagnostic methods have limitations in terms of predicting the ventilation function of the lungs after surgery. It was decided to investigate the possibilities of dual-energy CT (DECT) using xenon in clinical practice. The essence of the method is the ability to accurately assess the functional state of the lungs with the further prediction of surgical interventions. For the study, 10 patients with different pulmonary pathologies were selected (4 - COPD, 4 - lung cancer, 2 - bronchiectasis). Based on the data obtained, it was found that the use of DECT with xenon reflects the functional state of lung tissue, and also have potential for planning surgical intervention and introducing the method into modern protocols of preoperative preparation.
