Extending the Age Range in Mammography Screening: A Benefit-Risk Assessment from a Radiation Protection Perspective Open
Mammography screening programs (MSP) are established for women age 50 to 69 years in Germany and Europe. Some of the studies that build the evidence base for these programs also included women who were younger or older than this target pop…

Significant incidents during X-ray exposures in humans – assessment and findings of the Federal Office for Radiation Protection Open
In Germany, significant incidents must be reported to the competent authority since 12/31/2018 (section 108 Radiation Protection Ordinance (StrlSchV)). After assessment and evaluation of the reports, the competent authority submits the rel…

Reproduction of a conventional anthropomorphic female chest phantom by 3D‐printing: Comparison of image contrasts and absorbed doses in CT Open
Background The production of individualized anthropomorphic phantoms via three‐dimensional (3D) printing methods offers promising possibilities to assess and optimize radiation exposures for specifically relevant patient groups (i.e., over…

Dose‐efficiency quantification of computed tomography systems using a model‐observer Open
Background Recent advances in computed tomography (CT) technology have considerably improved the quality of CT images and reduced radiation exposure in patients. At present, however, there is no generally accepted figure of merit (FOM) for…

Tissue equivalence of 3D printing materials with respect to attenuation and absorption of X‐rays used for diagnostic and interventional imaging Open
Introduction Three‐dimensional printing is a promising technology to produce phantoms for quality assurance and dosimetry in X‐ray imaging. Crucial to this, however, is the use of tissue equivalent printing materials. It was thus the aim o…

Lung Cancer Screening with Low-Dose CT: Radiation Risk and Benefit–Risk Assessment for Different Screening Scenarios Open
Lung cancer is a severe disease that affects predominantly smokers and represents a leading cause of cancer death in Europe. Recent meta-analyses of randomized controlled trials (RCTs) have yielded that low-dose computed tomography (LDCT) …

Lung Cancer Screening with Low-Dose CT in Smokers: A Systematic Review and Meta-Analysis Open
Lung cancer continues to be one of the main causes of cancer death in Europe. Low-dose computed tomography (LDCT) has shown high potential for screening of lung cancer in smokers, most recently in two European trials. The aim of this revie…

COPD Imaging on a 3rd Generation Dual-Source CT: Acquisition of Paired Inspiratory-Expiratory Chest Scans at an Overall Reduced Radiation Risk Open
As stated by the Fleischner Society, an additional computed tomography (CT) scan in expiration is beneficial in patients with chronic obstructive pulmonary disease (COPD). It was thus the aim of this study to evaluate the radiation risk of…

Double-strand breaks in lymphocyte DNA of humans exposed to [18F]fluorodeoxyglucose and the static magnetic field in PET/MRI Open
Background Given the increasing clinical use of PET/MRI, potential risks to patients from simultaneous exposure to ionising radiation and (electro)magnetic fields should be thoroughly investigated as a precaution. With this aim, the genoto…
