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.

Also, an energy-saving mode was activated for one of the scanners. Previously, the scanners were only shut down on some days, and no energy-saving mode was active. We determined the energy savings by measuring the power consumption in the section of the building where the two MRI scanners are housed and comparing it with previous values.By shutting down both MRIs at night, the building section's power consumption could be reduced by 7.04 kW, and by activating the energy-saving mode by an additional 2.15 kW. Through these measures, annual energy savings of up to 25000 kWh were achieved. This corresponds to a cost reduction of approx. EUR 4200, as well as a reduction in CO₂ emissions of about 10t. According to our measurements, a hospital that has previously left its MRIs ready for scanning at all times would save up to 20000 kWh per year per scanner, which corresponds to approx. EUR 3300 in cost savings and a reduction in CO₂ emissions of approx. 8t. In addition, there was no noticeable impact on the quality of patient care.Energy-saving measures in radiology departments can be implemented effectively and with little effort by changing the manner of operation of MRI scanners. · Shutting down MRIs outside of routine operating hours reduces power consumption. · Activating an energy-saving mode further reduces consumption. · Implementing these measures is simple and has no identifiable disadvantages. · Thurner J, Fellner C, Stroszczynski C et al.

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.

Its members, i.e. users and manufacturers, developed solutions with a focus on state-of-the-art technology, fulfilment of legal requirements, practical usability, and implementability. Additional framework conditions to be considered were data transfer as an HTTP link and the use of ZIP containers with a mandatory IHE PDI media structure that can optionally be supplemented by an IHE XDM media structure.The results are summarized in DIN/TS 19455 DICOM Link Exchange (DLX), which defines the content of the media for the transmission of access data, the content and format of the virtual patient CDs, as well as an OpenAPI-based interface for automated data access. In addition, DIN/TS establishes the minimum functional requirements for manual data access.DICOM Link Exchange enables the integration of virtual patient CDs in clinical processes and has the potential to replace physical data media. In combination with the MIO Image Report and the use of the gematik email service KIM for data transmission, there is now the possibility of a nationwide digital exchange of radiological images and reports without a complex infrastructure. · DLX enables the integration of virtual patient CDs in clinical workflows.. · DLX has the potential to replace physical patient CDs.. · DLX can speed up digitalization in healthcare.. · Kämmerer M, Engelmann U, Eßeling R et al.

DDVD is calculated according to: DDVD(b0b20) = Sb0/ROIarea0 - Sb20/ROIarea20, where Sb0 and Sb20 refer to the tissue signal when b is 0 or 20 s/mm². This study applied DDVD to assess the perfusion of parotid gland tumors.MRI was performed at 3.0T. Diffusion-weighted images with b-values of 0, 20, 1000 s/mm² were acquired for 24 pleomorphic adenomas (PA), 16 Warthin's tumors (WT), and 14 malignant tumors (MT). DDVDr was DDVD of the tumor divided by DDVD of tumor-free parotid gland tissue. A systematic literature search was conducted for parotid gland tumor perfusion imaging studies. Perfusion parameters of PA, MT, and WT were normalized by PA value, and thus the ratio for PA value was assumed to be 1. The ratio results of MT DDVDr and WT DDVDr further normalized by PA DDVDr were compared with the literature results. In addition, the ADC (apparent diffusion coefficient) was calculated with b=0, 1000 s/mm² images.Most of the tumors were hyper-vascular relative to native parotid gland tissue with DDVDr >1, with PA, MT, and WT having mean DDVDr values of 1.753±0.462, 2.731±2.254, and 4.324 ±3.203, respectively. DDVDr ratios of MT/PA and WT/PA agreed with the literature perfusion results derived with non-DWI methods, particularly consistent with CT perfusion blood volume results. PA, MT, and WT had ADC values of 1.485 ±0.36, 0.969± 0.194, and 0.772± 0.070 (×10^-3 mm²/s), respectively. WT had very high DDVDr and low ADC, while PA had moderately high DDVDr and very high ADC. Most of the MTs had moderately high DDVDr and low ADC. A combination of ADC and DDVDr can largely differentiate between PA and WT.DDVD results approximately agree with parotid gland perfusion imaging literature data. A combination of DDVD and ADC may support parotid gland tumor tissue characterization. · As a straightforward diffusion MRI biomarker, DDVD can be used to assess parotid gland tumor perfusion.. · Warthin's tumors have very high DDVD and low ADC.. · Pleomorphic adenomas have moderately high DDVDr and very high ADC.. · A combination of ADC and DDVDr can largely differentiate between pleomorphic adenoma and Warthin's tumor.. · Yao D, King AD, Zhang R etal.
