Dual-Energy Ct With Xenon in Patients With Lung Pathology. First Data

Abstract

Routine diagnostic methods have limitations in terms of predicting the ventilation function of the lungs before and after surgery. It was decided to investigate the possibilities of dual-energy CT (DECT) using xenon in assessment of lung ventilation function.Objective: to master the methods of examination of patients with pulmonary pathology, evaluate the possibility of justifying the volume of operative intervention and prediction of postoperative lung function based on the hybrid images.Materials and methods. For the study, 12 patients with different pulmonary pathologies were selected (COPD – 5, lung cancer – 4, bronchiectasis – 3). Results. It was found that the use of DECT with xenon reflects the functional state of lung tissue.Conclusions. DECT with xenon have potential for planning surgical intervention and introducing the method into modern protocols of preoperative preparation.
