CT diagnostic reference levels based on clinical indications: results of a large-scale European survey
ConclusionsThis is the first study reporting on feasibility of establishing CT DRLs based on CI using European data. Resulting values will serve as a baseline for comparison with local radiological practice, national authorities when DRLs are set/updated, or as a guideline for local DRL establishment.Key Points•First study reporting on the feasibility of establishing CT diagnostic reference levels based on clinical indication using data collected across Europe.•Only one-fourth of the hospitals had CT machines less than 5 years old.•Large dose variations were observed among hospitals and CT protocols were quite differ...

Diagnostic reference levels and median doses for common clinical indications of CT: findings from an international registry
ConclusionsDRLs for CTDIvol and DLP for EUCLID clinical indications from diverse organizations were established and can contribute to dose optimization. These values were usually significantly higher in the US than in Europe.Key Points•Registry data were used to create benchmarks for 10 common indications for CT identified by the European Society of Radiology.•Observed US radiation doses were higher than European for 9 of 10 indications (except chronic sinusitis).•The presented diagnostic reference levels and median doses highlight potentially unnecessary variation in radiation dose.

Coronary artery calcification scoring system based on the coronary artery calcium data and reporting system (CAC-DRS) predicts major adverse cardiovascular events or all-cause death in patients with potentially curable lung cancer without a history of cardiovascular disease
In conclusion, the CAC-DRS score on non-gated standard CT can predict incident MACEs and/or all-cause death in patients with potentially curable resected lung cancer. Lung cancer survivors with a greater CAC-DRS category may need more active management of cardiovascular risk factors.

Pharmacological interventions for preventing atrial fibrillation after lung surgery: systematic review and meta-analysis
ConclusionCurrent clinical evidence supports the effectiveness of pharmacological intervention with beta-blockers, amiodarone, magnesium sulfate, or calcium-channel blockers to reduce the incidence of POAF after lung surgery in patients with lung cancer. In the absence of contraindications, prophylaxis with beta-blockers seems to be the most effective of the treatments studied.
