The increasing number of women working in medical surgical professions involving ionizing radiation creates new challenges for the safety of both pregnant and breastfeeding employees and the management of prenatal radiation exposure. The aim of this manuscript is to discuss the biological effects of loosely-ionizing radiation, evaluate the associated risks, and discuss the principles of German radiation protection law in the context of pregnancy and breastfeeding.To assess the effects of prenatal radiation exposure, we reviewed relevant sources such as reports from the German Commission on Radiological Protection, United Nations Scientific Commission on Effects of Atomic Radiation (UNSCEAR), and publications from the International Commission on Radiological Protection (ICRP). Additionally, the current German legislation, with focus on radiation protection and maternity protection laws, was outlined in context.The analysis shows that adhering to regulatory dose limits minimizes the risks of pregnancy complications, congenital malformations, developmental delays, mutagenic and carcinogenic effects. Special attention is required during the first trimester, in which radiation sensitivity is highest. Adherence to legal framework and associated protective measures in Germany provides under certain conditions a safe working environment for pregnant and breastfeeding women in surgical professions that involve ionizing radiation.This work highlights that careful risk assessment and strict adherence to radiation protection and occupational safety regulations enable pregnant and lactating women to work safely in areas associated with ionizing radiation and interventional aspects of their occupation. The need for continuous monitoring and adjustment of protective measures as well as the provision of confidential counseling services, are essential to ensure the safety of pregnant and breastfeeding workers and their children. · Becker LS, Stein T, Frisch A et al.

Magnetic resonance imaging (MRI) is an excellent method for visualizing the complex anatomical structures of the fingers. The high diagnostic standard is based on numerous recent technical developments to improve soft tissue differentiation and detail recognition, and includes time-resolved functional imagingThis review highlights the current status of MRI in finger diagnostics. The content of this narrative review is based on a literature search in the PubMed and Google Scholar databases using the search terms "finger MRI" and "finger imaging".Due to numerous technical optimizations and the increasing clinical availability of MRI, this examination has become indispensable in routine use for the further clarification of traumatic and orthopedic clinical pictures. MRI is also playing an increasingly important role in rheumatic and inflammatory issues, as well as tumors, whereby the particularly high potential for early detection and the detailed soft tissue imaging are especially advantageous. · MRI enables precise differential diagnosis of all clinical pictures of the fingers and is useful in the clarification of traumatic, orthopedic, rheumatic, inflammatory, and neoplastic issues.. · Multi-channel hand coils, scanners with high magnetic field strengths, and the use of contrast agents have led to an evaluation with resolutions in the submillimeter range in some cases.. · High-resolution MRI, including the possibility of functional examination, makes it easier to determine adequate therapy and avoid subsequent damage while meeting high standards.. · Bayer T, Lutter C, Janka R et al.

The randomized controlled, multicenter TOSYMA study showed a superiority of the combination of digital breast tomosynthesis and synthetic mammography (DBT+SM) over digital mammography (DM) in the detection rate of invasive breast cancer at stage UICC I. In this subanalysis, we compared the mammographic tumor signs of UICC I stage breast cancers detected in each study arm and stratified according to histological grade.This subanalysis included 49,462 women in the DBT+SM arm and 49,669 women in the DM arm after 1:1 randomization from July 2018 to December 2020. The mammographic abnormalities documented at the consensus conference were collected for breast cancers in stage UICC I based on various tumor signs (such as masses, microcalcifications, architectural distortions, or their combinations). The detection rates (per 10,000 screened women) were calculated with differentiation of grade 1 and grade 2 or 3 cancers.Grade 1 cancers were detected using DBT+SM in 6.5/10,000 screened women only by masses (+1.5/10,000 versus DM), in 2.4/10,000 (+1.6/10,000) by architectural distortions, and in 1.2/10,000 (+0.8/10,000) by microcalcifications. Combinations of tumor signs were present in 7.9/10,000 (+6.1/10,000) screened women. Grade 2 or 3 cancers were detected by DBT+SM in 13.7/10,000 by masses (+2.6/10,000 versus DM), in 4.9/10,000 by microcalcifications (+2.3/10,000), and in 3.6/10,000 by architectural distortions (+2.0/10,000). Combinations were present in 10.1/10,000 (+6.3/10,000) screened women.In DBT+SM screening, the detection rate of UICC I breast cancers is higher compared to DM: both, individual tumor signs and their combinations contribute to this finding. The detection rate of UICC I grade 2 or 3 cancers is higher in DBT+SM screening than in DM screening mainly due to the combination of tumor signs. · DBT+SM detects more grade 2 or 3-UICC I breast cancers than DM.. · This increase in detection rate results mainly from a combination of tumor signs.. · Nearly half of the increase relates to individual signs: masses, microcalcifications, and architectural distortions.. · Weigel S, Hense HW, Weyer-Elberich V et al.
