Objectives: To investigate the impact of the interventionalist's experience and gender on radiation dose and procedural time in CT-guided interventions.
Methods: We retrospectively analyzed 4380 CT-guided interventions performed at our institution with the same CT scanner from 2009 until 2018, 1287 (29%) by female and 3093 (71%) by male interventionalists. Radiation dose, number of CT fluoroscopy images taken per intervention, total procedural time, type of intervention, and degree of difficulty were derived from the saved dose reports and images.
The aim of this study was to evaluate the risk of pneumothorax and need for chest tube insertion in CT-guided lung biopsies and identify predictors focusing on pulmonary emphysema determined with quantitative computed tomography. To that end, we retrospectively analysed the incidence of pneumothorax and chest tube insertion in 371 CT-guided lung biopsies with respect to the quantitative emphysema score determined with the density mask technique. Other possible impact factors considered were lesion diameter, length of biopsy pathway within the lung parenchyma, lung lobe, needle size, puncture technique, patient positioning and interventionalist's level of experience.

Method: One hundred and twenty-six patients with BN (29 adolescents and 97 adults) were randomly allocated to a cognitive behavioural therapy-based self-help program delivered by the Internet or bibliotherapy, both accompanied by e-mail guidance. Outcomes were assessed at baseline, month 4, 7 and 18 including remission rates and eating disorder associated psychopathology.
