Wrist pain is common and can be attributed to tendon pathologies.This review aims to give a structured review of tendon anatomy, discuss anatomical pitfalls, and provide an overview of typical tendon pathologies of the wrist based on the current literature.Typical tendon pathologies of the wrist include de Quervain tenosynovitis, proximal and distal intersection syndrome, extensor and flexor pollicis longus tendon ruptures, and extensor carpi ulnaris subsheath injury. Typical pitfalls are multiple bundles of the abductor pollicis longus tendon or the centrally increased signal of the extensor carpi ulnaris tendon.Both ultrasound and MRI are appropriate modalities for assessing the tendons of the wrist. Knowledge of normal anatomy, variants, pathologies, as well as appropriate imaging is crucial to determine the diagnosis. · Multiple tendon bundles of the abductor pollicis longus are a common anatomical feature and should not be mistaken for tendon splitting.. · An anatomical pitfall resembles the frequently found centrally increased signal of the extensor carpi ulnaris tendon caused by fibrovascular tissue.. · In order to visualize the diagnosis of a proximal intersection syndrome, the MR scan field needs to include the area approximately 4 to 8 cm proximal to Lister's tubercle.. · The tendons of the thumb, i.e., extensor and flexor pollicis longus, are most commonly torn after distal radial fracture (EPL) and osseous hardware fixation (FPL).. · Marth T, Grob NA, Jacobson JA et al.

There has been a significant increase in the number of spinal surgical procedures performed over the last few decades, resulting in a proportionate increase in the number of postoperative imaging studies.An exhaustive literature search was performed along with consideration of various guidelines and expert opinions regarding postoperative spine imaging. Complications are divided into early (in the first few weeks) and delayed, depending on the time of onset. Some complications occurring in the early postoperative period are common for both the instrumented and non-instrumented spine. Delayed complications are specific to the type of surgery performed and have been described as such. This review discusses the normal postoperative appearance and the various early and delayed complications.An understanding of the normal postoperative appearance is pertinent to distinguish normal from abnormal. A plain radiograph is the primary imaging modality for immediate postoperative assessment and long-term follow-up after spinal instrumentation. MRI with or without contrast is the imaging modality of choice for the evaluation of the postoperative spine. CT is the best modality for the assessment of the instrumented spine and status of bony fusion. Imaging assessment of the postoperative spine is complex and requires knowledge of key factors for interpretation like indications for the initial surgical procedure, type and approach of the surgical procedure, instrumentation used, time elapsed since surgery, and clinical complaints. · For proper interpretation of the postoperative spine, it is very important to understand the indication and type of spinal procedure involved. · Baseline postoperative radiographs are important to detect any change in the position of metalwork and implant integration.. · Computed tomography is the modality of choice to evaluate bony fusion and metalwork-specific complications. · Postoperative fluid collection is the most common early complication and MRI is the imaging modality of choice for the identification of the same.. · Intravenous gadolinium is helpful to differentiate between scar/vascularized granulation tissue and recurrent or residual disc.. · Kaur S, Lalam R, Trivedi R.

To explore the peak enhancement time of a hepatocellular carcinoma, the pancreas, and the kidney cortex and its determinants.We obtained a time enhancement curve from the perfusion CT scans of 11 advanced HCC patients (40 volumes at 1.25 s time interval, slab slice 90 mm, bolus of 50 ml of iodinated contrast agent, 350 g iodine/ml, flow 5 ml/s). Small regions of interest were drawn on the abdominal aorta, the HCC, the cortex of the right kidney, and on the pancreas. The behavior of the contrast agent in the capillary and in the surrounding tissue was further explored with a finite element model.The peak enhancement time of the pancreas did not differ from that of the HCC (10±3 vs. 11±4 s, p=0.9), while the peak enhancement time of the kidney tended to be a few seconds earlier (8±1 s, p=0.082 vs. pancreas and p=0.069 vs. kidney). Simulation showed that the time span in which the tissue enhancement remained within 10% of its peak value was similar across all capillary densities and ranged between 26-38 s for a capillary density of 0.00125 per mm to 30-60 s for a capillary density of 0.01.The plateau tissue enhancement clinically acquired in the "late arterial phase" should be adequate both for the detection of hypervascular liver lesions such as HCCs and for obtaining peak pancreatic enhancement to detect hypovascular lesions. · The peak tissue enhancement time of an HCC, the pancreas, and the kidney cortex is similar. · The tissue peak enhancement time in the arterial phase is at the end of bolus transit. · Simulation shows that tissue enhancement peak time is a function of capillary density. · Cressoni M, Cadringher P, Colarieti A et al.

The aim of our study was to assess the attitudes towards AI and teleradiology and their current usage in pediatric radiology within German-speaking countries.From March to May 2023, we conducted an anonymous online survey among members of the Society for German-speaking Pediatric Radiologists (GPR) and the Swiss Society for Pediatric Radiology (SGPR) via the SurveyMonkey platform. The survey consisted of 25 items with rating scales and open-ended responses.Out of 418 society members, 36 completed the questionnaire (8.6%). Teleradiology (50% fully agree, 27.8% partly agree) and AI (38.9% fully agree, 22.2% partly agree) were considered relevant for pediatric radiology by the majority of respondents. Teleconsultation for second opinions is regularly used in 58% of the departments. Currently, AI does not play a significant role in the daily work of 52.8% of respondents. Beyond segmentation, AI is used primarily for image acquisition and dose reduction. Over 80% of respondents indicated that bone age determination is well-suited for an AI solution, yet only 31% routinely use such a solution.AI and teleradiology have a high level of acceptance in German-speaking pediatric radiology (Germany, Austria, Switzerland, i.e. the DACH region) and are seen as a possible strategy for improving pediatric radiology care. This contrasts with the current low level of use in clinical routine. · Pediatric radiologists in the DACH region consider AI and teleradiology to be important for pediatric radiology care.. · AI/teleradiology are seen as viable options to enhance pediatric radiology care.. · However, the actual use of AI/teleradiology in everyday routine is low.. · Sturm M, von Kalle T, Renz DM et al.

Military radiology, an integral part of military medicine, plays a pivotal role in medical triage, diagnosis, and treatment. Its significance lies in providing timely and accurate assessments in challenging situations.The utilization of contemporary sonographic techniques enables rapid identification of life-threatening conditions, ensuring prompt medical aid and facilitating regional anesthesia. Computed tomography emerges as a critical tool for assessing injury extent, planning surgeries, monitoring postoperative phases, and conducting retrospective evaluations, especially when anatomical dissection is complex.Battlefield radiology not only enhances the understanding of injury mechanisms and battlefield traumas but also contributes significantly to the overall improvement of diagnostic and treatment approaches. Ukrainian doctors actively engaged in diverse stages of patient care accumulate a wealth of knowledge, substantially elevating the survival rates of wounded individuals. This experience serves as the foundation for ongoing enhancements and the advancement of military radiology, even during periods of peace. · Military radiology is essential in medical triage, diagnosis, and treatment within military contexts.. · Modern sonographic methods enable swift identification of life-threatening conditions.. · Computed tomography is indispensable for assessing injuries, planning surgeries, and conducting retrospective evaluations.. · Ukrainian doctors actively contribute to the knowledge base, improving diagnostic and treatment practices.. · The acquired experience serves as a foundation for ongoing advancements in military radiology, extending its impact beyond wartime scenarios.. · Nehria N, Nehria Y, Bukharin T.

Worldwide, the study and examination of human remains and the circumstances of their acquisition for anatomical collection have received great interest. As part of provenance research projects, a large number of collections are being investigated to determine whether the human remains have been acquired in a correct or unlawful way because the people could have been killed in order to be used as "anthropological objects" for research purposes and to become so-called "specimens". These topics have also been addressed by the Institute of Anatomy at the University Medical Center Rostock. The role of radiology in this interdisciplinary project will be presented using selected examples.The anatomical collection at the University of Rostock includes 40 human skulls, 14 plaster casts, 6 Egyptian mummy heads, and 1 full-body mummy. In addition to the examination by a historian, an anthropologist, and forensic pathologists, additional computed tomography was carried out on nine skulls and the full-body mummy. Micro-computed tomography was also carried out on seven skulls in order to enable a look behind the mummification material and tissue remains.(Micro-)computed tomography was able to close diagnostic gaps and the results presented some rather unexpected findings.Due to interdisciplinary collaboration, individual fates could be determined, which provided information about the individual's life and death circumstances. None of the examined individuals showed evidence of colonial-era injustice or the use of violence that would have led to their inclusion in the collection. (Micro-)computed tomography was a valuable addition to this provenance research project. · Computed tomography enhances interdisciplinary provenance research projects.. · Computed tomography enables a non-destructive examination of human remains.. · The future of research and presentation of human remains will increasingly be virtual.. · Steinhagen I, Brinker U, Kolbe V et al.
