NCT07317479
The purpose of this clinical study is to evaluate the performance of the P-MAR metal artifact reduction algorithm for CT imaging (with metal present) of adult patients (\>18 years old). The study has two objectives: 1. To evaluate the extent of metal artifacts and diagnostic confidence, and overall image quality (independent of metal artifacts) of P-MAR compared to images without metal correction, and compared to O-MAR, for CT images (with metal present) of adult patients (\>18 years old). 2. To demonstrate non-inferiority of P-MAR compared to images without metal correction for the relevant metal groups.
NCT07317531
This randomized, single-blind, parallel-group controlled trial aims to investigate the effects of expiratory muscle training added to standard pulmonary rehabilitation on respiratory muscle strength, pulmonary function, cough effectiveness, exercise capacity, dyspnea perception, and quality of life in patients with non-cystic fibrosis bronchiectasis. Eligible patients aged 18-70 years with stable disease will be randomly assigned to either a pulmonary rehabilitation-only group or a pulmonary rehabilitation combined with expiratory muscle training group. Outcomes will be assessed at baseline and after completion of the intervention period.
