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.

The present article reviews recent advances in pulmonary computed tomography (CT) imaging, focusing on the application of dual-energy CT and the use of iterative reconstruction. Dual-energy CT has proven to be useful in the characterization of pulmonary blood pool in the setting of pulmonary embolism, characterization of diffuse lung parenchymal diseases, evaluation of thoracic malignancies and in imaging of lung ventilation using inhaled xenon. The benefits of iterative reconstruction have been largely derived from reduction of image noise compared with filtered backprojection reconstructions which, in turn, enables the use of lower radiation dose CT acquisition protocols without sacrificing image quality. Potential clinical applications of iterative reconstruction include imaging for pulmonary nodules and high-resolution pulmonary CT.

<p class="abstract"><strong>Background:</strong> <span lang="EN-IN">SDB is an important cause of morbidity in children. SDB has been associated with decreased quality of life (QOL). In this study, we tried to determine The impact of surgical intervention (adenotonsillectomy) and conservative management on quality of life in patients with SDB. </span></p><p class="abstract"><strong>Methods:</strong> <span lang="EN-IN">A total of 112 pediatric patients were included with SDB, who visited our OPD. Diagnostic methods include history and physical examination, audiotaping or videotaping, pulse oximetry. OSA 18 questionnaire was used to assess the quality of life with conservative treatment (pre and post-treatment) and after surgical intervention-before and after adenoidectomy or adenotonsillectomy.  </span></p><p class="abstract"><strong>Results:</strong> <span lang="EN-IN">We had 112 patients with majority being males 69 (61.60%) and females 43 (38.30%), majority of patients were in the age group of 5-7 yrs (49.10%). In 47 patients (who underwent adenotonsillectomy/tonsillectomy), OSA-18 questionnaire was used pre-operatively, at 2 and 6 months. OSA-18 when used pre-operatively showed majority of patients 33 (70.21%) having score &gt;80, and 14 (29.79%) patients having score between 60-80. No patient was below 60 score. Mean OSA-18 score pre-operatively was 84.15. OSA-18 score at 2 months and at 6 months were 30.06 and 26.40 respectively, which showed a lot of improvement in post-operative score and hence the post –operative quality of life. In 65 patients (conservative treatment) OSA-18 was used pre-conservative, at 2 and 6 months of treatment. OSA-18 when used before conservative treatment<strong> </strong>showed majority of patients 44 (67.6 9%) having score 60-80, and 21 (32.30%) patients having score between &gt;80. No patient was below 60 score. OSA-18 score at 2 months showed improvement in 69.23% patients (&lt;40), OSA-18 at 6 months showed recurrence in 12.33% patients. </span></p><p class="abstract"><strong>Conclusions:</strong> <span lang="EN-IN">SDB substantially impact QOL in pediatric patients. QOL significantly improves following adenotonsillectomy. There is subset of patients 12.33% with SDB in whom there was recurrence of symptoms after conservative treatment. Thus showing that conservative management is inferior to surgical management in the treatment of SDB. SDB improved after an observation period. Thus, observation with close follow-up is another treatment option.</span></p><p> </p>
