Chronic airflow limitation and its relation to respiratory symptoms among ever-smokers and never-smokers: a cross-sectional study

Publikováno v: BMJ Open Respiratory Research, Vol 7, Iss 1 (2020)

Background The diagnosis of chronic obstructive pulmonary disease is based on the presence of persistent respiratory symptoms and chronic airflow limitation (CAL). CAL is based on the ratio of forced expiratory volume in 1 s to forced vital capacity

Evaluation of deep‐learning image reconstruction for chest CT examinations at two different dose levels

Autor: Angelica, Svalkvist, Erika, Fagman, Jenny, Vikgren, Sara, Ku, Micael Oliveira, Diniz, Rauni Rossi, Norrlund, Åse A, Johnsson

Publikováno v: Journal of Applied Clinical Medical Physics. 24

The aims of the present study were to, for both a full-dose protocol and an ultra-low dose (ULD) protocol, compare the image quality of chest CT examinations reconstructed using TrueFidelity (Standard kernel) with corresponding examinations reconstru

Multi-Reader–Multi-Split Annotation of Emphysema in Computed Tomography

Autor: Mats Lidén, Ola Hjelmgren, Per Thunberg, Jenny Vikgren

Publikováno v: Journal of Digital Imaging

Emphysema is visible on computed tomography (CT) as low-density lesions representing the destruction of the pulmonary alveoli. To train a machine learning model on the emphysema extent in CT images, labeled image data is needed. The provision of thes
