Multiparametric ultrasound has proven to be a fundamental and valuable imaging modality in this context, improving early-phase sensitivity through various techniques, including B-Mode, color Doppler, power Doppler, pulsed Doppler, microflow studies, and elastography. In this context, Contrast-Enhanced Ultrasound (CEUS) emerges as a rapid, safe, and valuable tool in enhancing diagnostic accuracy and therapeutic decisions for acute scrotal conditions. This study involves a detailed analysis of various ultrasound imaging techniques and investigates the optimal circumstances and methods for employing CEUS in emergency situations to improve diagnostic accuracy and therapeutic decisions. Multiparametric ultrasound plays a crucial role in diagnosing various pathologies, including testicular torsion, appendage torsion, inflammation, ischemia/infarction, and trauma. CEUS provides real-time assessment of vascular perfusion, aiding in early diagnosis and accurate characterization of scrotal pathologies and significantly reducing the need for unnecessary surgical interventions, especially in trauma cases. Its role in differentiating between various pathologies and guiding therapeutic decisions underscores its importance in clinical practice, contributing significantly to improve patient outcomes.","PeriodicalId":51528,"journal":{"name":"Journal of Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144026168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These fractures are treated conservatively or surgically depending on deformity severity. Radiographs are typically used for diagnosis but can increase wait times due to the need for radiation-safe rooms. Ultrasound (US) offers a radiation-free, faster alternative that can be performed at triage, but its noisy images are challenging to interpret.Methods: We developed an artificial intelligence (AI) technique for the automatic diagnosis of fractures at the wrist and elbow. While most AI for diagnosis focuses on classification results only, we applied a more explainable pipeline that used US bony region segmentation from a CNN as the basis of fracture detection. Our approach was validated on 3,822 wrist US images and 1487 elbow US images. We compared the fracture detection results from classification models and multi-channel segmentation models.Results: Combining the segmentation results with the original images showed superior performance in fracture detection at the individual patient level, achieving an accuracy of 0.889 and 0.750, sensitivity of 0.818 and 1.000, and specificity of 1.000 and 0.714 on the wrist and elbow dataset respectively. Besides, the multi-channel U-Net architecture effectively detected bony fracture regions in wrist US images.Conclusion: These findings demonstrate that AI models can enable reliable, automatic wrist and elbow fracture detection in pediatric EDs, potentially reducing wait times and optimizing medical resource use.","PeriodicalId":51528,"journal":{"name":"Journal of Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144016912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each CET tenotomy was performed using a Mikro 64 scalpel under ultrasound guidance to ensure precision and safety. Key anatomical structures, including the lateral collateral ligament (LCL), radial nerve, and posterior antebrachial cutaneous nerve, were monitored to assess safety margins and detect potential complications.Results: In the 20 evaluated cases, the mean distance from the CET section to the radial epicondyle (DET) was 5.86 mm (range 5.96-12.8 mm), while the distance to the proximal LCL margin (DELCL) averaged 8.62 mm (range - 0.96-6.82 mm), yielding a confident tenotomy length of 2.76 mm. Partial LCL injury occurred in four cases without affecting joint stability, and no nerve injuries were observed. Incomplete CET sections were found in four cases, with residual fibers primarily along the medial and lateral margins.Conclusion: The ultrasound-guided percutaneous tenotomy technique demonstrated safety and effectiveness in an anatomical setting. This minimally invasive approach may offer a viable surgical alternative for refractory lateral epicondylitis, minimizing the risk of complications and promoting a shorter recovery period.","PeriodicalId":51528,"journal":{"name":"Journal of Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144063061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the contrary, despite the importance of ultrasound, training is significantly variable across medical education, thereby leaving gaps in competency among graduates. In light of the aforementioned fact, ultrasound training is increasingly part of medical curricula; however, practical exposure remains limited due to logistic barriers. This cross-sectional study assesses ultrasound knowledge among 213 medical students across six academic years in the Kurdistan Region of Iraq. Results show that 95.3% of the students know that ultrasound is applied outside obstetrics, hence showing a general comprehension of its area. However, 43.7% of students wrongly believe that exposure to ultrasound radiation is involved, whereas only 56.8% appropriately recognize clinical contraindications, identifying residual misunderstandings. Knowledge improved with advancing year of study. For instance, knowledge that ultrasound is non-radiative increased from 17.6% in students in their first year to 95% in those in the sixth year (p < 0.001). Similarly, the use of ultrasound gel is known to 54.1% of the students in the first year, with this number increasing to 100% in the sixth year of study (p < 0.001). The overall ratings of students' knowledge were: fair, 86.4%; good, 8.5%; and poor, 5.2%. These results also indicate that more comprehensive ultrasound education in terms of ensuring proficiency is necessary, and misconceptions have to be dispelled among future physicians. This study is the first study which conducted in Kurdistan region of Iraq, therefore we think that it is important to know the medical students then the medical education program related to sonography can be changed according to the result.","PeriodicalId":51528,"journal":{"name":"Journal of Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143991766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this regard, contrast enhanced ultrasound (CEUS) could be utilized to evaluate RT functional recovery and potentially detect acute rejection (AR) and/or renal ischemia signs.Materials and methods: Observational study of 107 consecutive patients waitlisted for RT. Participants underwent conventional ultrasound (CUS) and color-doppler-ultrasound (CDUS) to evaluate resistive index of segmental and interlobar arteries and quantitative CEUS techniques recording the following perfusion parameters: peak intensity (PI-c), rising time (RT-c), area under (AUC-c) the time intensity curve (TIC), time to peak (TTP-c) and mean transit time (MTT-c).Results: CEUS parameters sensibility and specificity to predict AR in the early post-operative period resulted in: 90% and 69% for PI-c, 95% and 64% for RT-c, 85% and 65% for AUC-c. The overall diagnostic performance of these three CEUS parameters in comparison to the same in CUS and CDUS resulted in a sensitivity and specificity of 95% and 49%, versus 85% and 46%, respectively, therefore CEUS examination with the analysis of PI-c, RT-c and AUC-c values increases the diagnostic sensitivity in predicting AR by approximately 15-20% compared to CDUS and by 30-40% compared to CUS.Conclusion: CEUS could be routinely included in RT follow-up, as it shows to be a non-invasive helpful diagnostic tool for early detection of renal graft complications, selecting patients eventually in need of further confirmation.","PeriodicalId":51528,"journal":{"name":"Journal of Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143781586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hepatic vein Doppler waveform, typically triphasic, may become biphasic or monophasic in cirrhosis, correlating with liver dysfunction, fibrosis, inflammation, and portal hypertension. This study investigates liver ultrasound (US) features in COVID-19 patients, correlating hepatic vein Doppler waveform and portal vein velocity (PVV) with inflammatory indexes and clinical outcomes.Methods: Fifty-seven patients with SARS-CoV-2 infection participated in a crosssectional study. Bedside upper abdomen US evaluations, including B-mode and Doppler, were conducted using a convex probe. Hepatic vein Doppler waveforms were classified as triphasic, biphasic, or monophasic, and the hepatic vein waveform index (HVWI) was calculated. PVV was measured over three cardiac cycles. Tracings were blindly analyzed by three operators to ensure consistency.Results: Low HVWI and high PVV correlated with elevated LDH, ALT, D-dimer, and ferritin (p < 0.05). HVWI showed significant negative correlations with ferritin, D-dimer, and ALT (p < 0.05). D-Dimer and ferritin were higher in patients with biphasic/monophasic waveforms (p < 0.05). High PVV and larger spleen diameters predicted worse respiratory outcomes, including CPAP and tracheal intubation (p < 0.05). Optimal cut-off values for PVV (21.7 cm/s) and spleen diameter (9.84 cm) maximized sensitivity and specificity for predicting these outcomes. FIB-4 scores did not correlate with respiratory outcomes or hepatic hemodynamics (p > 0.05). Hemodynamic alterations were not significantly influenced by the presence of SLD (Steatotic Liver Disease).Conclusions: COVID-19 patients exhibit altered intrahepatic hemodynamics, with hepatic vein waveform abnormalities potentially reflecting liver inflammation and fibrosis.
