B-mode and Doppler ultrasound are considered the modalities of choice for the imaging of the renal arteries. However, an adequate examination can be plagued by difficulties in patients with unfavorable anatomy. UltraFastTM ultrasound is faster, performed with higher frame rates, and enables prospective and ret- rospective data analysis with quantification of flow data in the obtained image, so it may be able to resolve some of the difficulties encountered during conventional ultrasound examinations in patients with suspected renal artery disease. Material and methods: Comparison of the duration of conven- tional and UltraFastTM Doppler examinations of segmental renal arteries was performed on 52 young, healthy volunteers. Duration times were summarized using the median and interquartile range, and comparisons between the two methods were performed using the Wilcoxon test for paired samples. Results: The duration of UltraFastTM ultrasound examinations was significantly shorter in comparison to conventional ultrasound for both kidneys and in total (p <0.001, median difference in duration 65 s, median 64% shorter duration of analysis), while both conventional and UltraFastTM ultrasound examina- tions demonstrated consistent velocity measurements with very high correlation (Rho = 0.94, p <0.001). Conclusions: The study provides evidence that UltraFastTM ultrasound is faster than conventional Dop- pler ultrasonography for the assessment of renal artery disease in healthy adults without a history of renal disease. The findings have important implications for clinical practice, as they suggest that Ultra- FastTM imaging could offer a more efficient and time-saving approach to vascular imaging in patients with suspected renal artery disease.","PeriodicalId":45612,"journal":{"name":"Journal of Ultrasonography","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140716097","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}

{"title":"Overview for developing Delphi-based interdisciplinary consensus statements on imaging: pros and cons","authors":"Tobias Johannes Dietrich1, V. Mascarenhas, Luis Cerezal, P. D. Afonso, I. Sudoł-Szopińska","doi":"10.15557/jou.2024.0015","DOIUrl":"https://doi.org/10.15557/jou.2024.0015","url":null,"abstract":"This review paper offers a concise guide on how to execute Delphi-based interdisciplinary consensus statements on imaging. Fundamental to the Delphi methodology are several core principles. First, an initial key element is the selection of experts, known as panelists. Second is the principle of anonymity among participants, ensuring that no single individual or group applies excessive influence over others. Third, the methodology involves iterative rounds where statements are presented repeatedly, allowing for controlled feedback. Lastly, after each round, participants are given insight into the collective panel’s previous responses. This knowledge enables them to potentially reconsider and adjust their positions in subsequent rounds, driving towards the group consensus. These principles emphasize the critical role of statistical group responses and the structured interaction inherent in the Delphi approach. Looking at the broader process, the development of Delphi-based interdisciplinary consensus statements on imaging unfolds through several stages. It begins with identifying the research field or the consensus statements in question. This is followed by undertaking comprehensive literature research. Subsequently, pertinent questions and their corresponding statements are crafted. The process then moves on to administering anonymous, iterative questionnaire rounds. Feedback, both on an individual and collective level, is provided between the rounds. The process culminates in the summarization and reporting of the finalized Delphi-based interdisciplinary consensus statements on imaging.","PeriodicalId":45612,"journal":{"name":"Journal of Ultrasonography","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140715715","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}

Smereczyński, Katarzyna Kołaczyk, Grzegorz Goncerz","doi":"10.15557/jou.2024.0014","DOIUrl":"https://doi.org/10.15557/jou.2024.0014","url":null,"abstract":"The ileocecal valve is a part of the gastrointestinal tract that separates two intestinal segments differing in both anatomy and function. Dysfunction or surgical removal of the valve usually results in the develop- ment of small intestinal bacterial overgrowth syndrome. The available literature lacks a broader discus- sion and ultrasound presentation of the ileocecal valve. The aim of this study is to present our experience in transabdominal ultrasound of the ileocecal valve in comparison with colonoscopic and computed tomography colonography data. In this part of the manuscript, we discuss the anatomical structures in the right iliac fossa that make up the ileocecal segment of the intestine. The ileocecal valve, which comes in two morphological forms: labial and papillary, is its central part. As shown in computed tomography colonography, the first type is more common, accounting for 76%, the second type accounts for 21%, whereas ileocecal valve lipomatosis is found in 3% of cases. Post-mortem studies have shown a signifi- cantly higher incidence of valve lipomatosis, which was found in up to 4 out of 5 cases. Our observations correspond with these findings. Ileocecal valve lipomatosis presents on ultrasound as a hyperechoic, well-circumscribed lesion, with no evident vascularity on color Doppler. This image should be differ- entiated especially from a lipoma, a relatively common large intestinal pathology. The paper presents two methods of preparation for an ultrasound scan (i.e. only on an empty stomach or after cleansing the intestine) and determines the optimal imaging methods for the ileocecal valve using transabdominal ultrasound. At the end of the ileocecal examination, it should be remembered to assess the lymph nodes in the right iliac fossa.","PeriodicalId":45612,"journal":{"name":"Journal of Ultrasonography","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140715576","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}

Material and methods: A case-control study was carried out after enrolling 50 patients with sickle cell disease (HbSS phenotype) (sickle cell disease group) and 50 con- trol subjects (control group). All the participants underwent ultrasound and color Doppler examination, and the pulsatility index and resistive index values of the main renal artery, segmental artery, and interlobar artery in both kidneys were recorded and compared. Results: The Doppler measurements of the main renal artery, segmental artery, and interlobar artery were compared between the control and sickle cell disease groups. It was found that both pulsatility index and resistive index were significantly higher in the sickle cell disease group, as compared to the control group, for the main renal artery, segmental artery, and interlobar artery (p <0.0001, p <0.0001, and p <0.0001, respectively). The optimal cut-off points for mean pulsatility index and resistive index, as measured by the Youden index, were found to be >1.08 (72% sensitivity and 88% specificity) and >0.635 (66% sensitivity and 98% specificity), respectively.
