For COPD classification in a medical imaging system, machine learning is used to learn to classify whether a patient has COPD. An image-to-image network deep learns spatial features indicative of various or any type of COPD. The pulmonary function test may be used as the ground truth in ...
The lung+vessel (AUC=0.83) and the airway+vessel model (AUC=0.85) obtained higher performance than the lung only model (AUC=0.78; p<.05).Conclusion: Inclusion of CT features extracted from the pulmonary vessels improves classification of COPD in a mild COPD cohort.European Respiratory Journal...

On comparing the BODE index, GOLDABCD, GOLD2017 and cluster analysis for predicting mortality, cluster system was found to be superior compared with GOLD2017 (0.654 vs 0.722, P=0.006), without significant differences between other classification models. When cardiovascular comorbidities and chronic ...
COPD-ES Questionnaire Intervention Improves COPD Patients’ Group Classification Baseline CAT scores did not differ significantly between the control and intervention groups (P=0.908). After 6 months, the intervention group’s CAT score (15.49 ± 4.734) was significantly lower than the control group’...
The lobe-based radiomics workflow for COPD stage classification Full size image Preprocessing The segmentation of lung lobes is performed by using the Seg-Lobe model, which is based on 3D U-Net [28] and implemented as the automatic pipeline to train, validate, and test the network using the ...
ClassificationThe classification of COPD is according to post-bronchodilator FEV1. Post-bronchodilator FEV1 often causes confusion. It means that if patients are using short-acting bronchodilators, the measurement is taken 15 minutes after the administration of 400 microgram salbutamol. If patients are ...
Table 1 Classification of exacerbations Full size table Exacerbations are characterised by an initial increase in airway inflammation, resulting in airway oedema, mucus production and bronchoconstriction (Fig. 2) [68]. An acute exacerbation is a serious event triggering a catastrophic cascade that is ...
