CT-guided Lung Biopsy Risk Optimization Method

The purpose of this randomized controlled study is to evaluate the extent to which injection of a small amount of fluid in the pleural cavity at the biopsy site may reduce the risk of pneumothoraces, in addition to patient positioning to allow biopsy in gravity-dependent areas of the lung.

Dosimetric Reference Levels for Radioguided Interventional Procedures in Rhythmology.

Interventional radiology has become a widespread technique used in various fields of medicine to diagnose or treat numerous pathologies. However, the risk of X-rays must be taken into account. In 2019, the French Authority on Nuclear Safety published diagnostic reference levels for radio-guided interventional practices for 10 interventional radiology procedures and 2 interventional cardiology procedures, based on studies published by the French Society of Medical Physics in collaboration with the French Society of Radiology and the French Coronary Artery Disease and Interventional Cardiology Group. Reference levels for interventional procedures under CT guidance were also defined in 2020 following a national multicenter study coordinated by Nîmes University Hospital (NIMAO NRD-SI). However, no national multicentre studies have ever defined reference levels for radioguided interventional procedures in rhythmology. The aim of this study is to define standard national dosimetric levels for a number of radioguided interventional procedures in rhythmology.
