After assessment and evaluation of the reports, the competent authority submits the relevant information via a web-based reporting system (BeVoMed) to the Federal Office for Radiation Protection (BfS), which publishes the results derived therefrom. The present paper evaluates significant incidents related to X-ray exposures on humans.All reports on incidents in X-ray diagnostics and interventional radiology between 01/2019 and 10/2023, which were completed with detailed information until the reporting day (31/10/2023), were included. The following aspects were statistically evaluated: classification as an incident (section 1 subsection (22) StrlSchV), significance (section 108 StrSchV), classification to Annex 14 StrlSchV, assignment to the forms of care in the German healthcare system, and development of the reporting frequency over time. Furthermore, the content of the reports was systematically evaluated with regard to conspicuous clusters and typical problems.Until the reporting day, 383 reports (355 completed) were received. 252 reports (228 in X-ray diagnostics, 24 in interventional radiology) referred to significant incidents and were included in the detailed evaluation. Reporting frequency increased in X-ray diagnostics, whereas there was no trend in interventional radiology. Most of the significant incidents concerned examinations on an individual person (category I, criterion 2a or category II, criteria 2a and 3a) in the in-patient sector - especially in maximum care hospitals. Frequent errors concerned the inappropriate choice of parameters/protocols or were related to the administration of a contrast agent. Despite the overall positive trend, the establishment of awareness and error culture remains challenging. · In X-ray diagnostics, the reporting frequency of significant incidents increases.. · Most incidents concerned CT examinations in the in-patient sector.. · Main problems were selection of protocols/settings, contrast administration, and bolus-tracking.. · Uncertainties remain about the classification of an incident as significant and notifiable.. · Winter KS, Schweden M, Brix G et al.

Moreover, the usage of structured reporting using LI-RADS and mRECIST was surveyed and the results were compared with a survey from 2020.Radiologists working in outpatient or inpatient care in Germany were invited. The survey was conducted between 10/2022 and 06/2023 and between 06/2024 and 08/2024. HCC-related questions were asked regarding the commonly used imaging modalities, body coverage, and contrast phases in CT, as well as the usage of structured assessment and treatment response using mRECIST and LI-RADS.More than half of the participants stated that they \"frequently\" perform imaging of HCC. In the CT protocol, acquisition of a pre-contrast phase was widespread. While a late arterial and a portal venous contrast phase was acquired in most cases, a delayed phase was used much less frequently (at small and medium-sized hospitals only in 26.5%). For staging, LI-RADS was used in structured reports in only 13%; for response monitoring mRECIST was used at university hospitals in only 26.5% and LI-RADS in 14.7%, whereas these have been almost never used in routine practice at all other sites. The main reasons given for the lack of application were the expenditure of time, the lack of reporting templates, problems with integration into the IT infrastructure and a lack of reimbursement.The recommendation of a three phase CT examination in late arterial, portal venous, and delayed phase for HCC diagnostics according to LI-RADS is only partially implemented in Germany. Structured reporting for staging and response monitoring using LI-RADS and mRECIST was at a similarly low level in Germany in 2023 compared to 2020. Possible solutions include the development and distribution of online educational resources, structured reporting templates, and inexpensive IT solutions. · The CT protocols in HCC diagnostics in Germany differ considerably with regard to the contrast phases acquired.. · Definition of a late arterial (approx. 15-20s p.i.; 5-15s after aortic peak), portal venous (approx. 60-80s p.i.) and delayed phase (2-5min p.i.) as well as a pre-contrast phase only after TACE may improve quality of CT diagnostics of HCC.. · The use of structured reporting using LI-RADS, LR-TR and mRECIST in HCC remained low in 2023/2024, similar to 2020.. · The use of LI-RADS and mRECIST could be improved by providing online educational resources, structured reporting templates, and inexpensive IT solutions.. · Nelles C, Ristow I, Juchems MS et al.

In particular, the introduction of photon-counting computed tomography (PCCT) in CT diagnostics promises significant advances through higher temporal and spatial resolution, and also enables advanced texture analysis, known as radiomics analysis. Originally developed in oncological imaging, radiomics analysis is increasingly being used in cardiac imaging and research. The aim is to generate imaging biomarkers that improve the early detection of cardiovascular diseases and therapy monitoring.The present study summarizes the current developments in cardiac CT texture analysis with a particular focus on evaluations of PCCT data sets in different regions, including the myocardium, coronary plaques, and pericoronary/epicardial fat tissue.These developments could revolutionize the diagnosis and treatment of cardiovascular diseases and significantly improve patient prognoses worldwide. The aim of this review article is to shed light on the current state of radiomics research in cardiovascular imaging and to identify opportunities for establishing it in clinical routine in the future. · Radiomics: Enables deeper, objective analysis of cardiovascular structures via feature quantification.. · PCCT: Provides a higher quality image, improving stability and reproducibility in cardiac CT.. · Early detection: PCCT and radiomics enhance cardiovascular disease detection and management.. · Challenges: Technical and standardization issues hinder widespread clinical application.. · Future: Advancing PCCT technologies could soon integrate radiomics in routine practice.. · Ayx I, Bauer R, Schönberg SO et al.
