Maceration using an expandable nitinol disk may be useful in these situations, but its safety has not been determined. The purpose of this study was to retrospectively assess the safety of this device when applied in the pulmonary vasculature, using a propensity-score matched group for comparison.Materials and methods: Inclusion criteria consisted of patients who underwent PE thromboembolectomy within a single healthcare system between December 2020 and December 2022 and subsequently underwent suction thromboembolectomy in which the nitinol disk was used. A comparator group was generated from the remaining patients who underwent conventional PE thromboembolectomy by performing one-to-one propensity-score matching based on age, PE risk category, and sPESI score.Results: Out of a total of 164 patients who underwent pulmonary thromboembolectomy during the study period, the disk was utilized in 28. The disk was used in the left pulmonary artery in nearly 80 % of patients and in the right pulmonary artery in less than 40 %. Initial, final, and change in mean pulmonary artery pressures were not significantly different between groups. Similarly, mean duration of hospitalization, number of complications, and 30-day mortality rate did not differ.Conclusion: Use of a nitinol disk during pulmonary thromboembolectomy is safe despite administration of anticoagulation. Clinical effectiveness remains to be determined.","PeriodicalId":50680,"journal":{"name":"Clinical Imaging","volume":"118 ","pages":"110381"},"PeriodicalIF":1.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142787538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiplanar pre- and post-contrast HASTE, T1-VIBE, and high-resolution breath-held 3D MRA sequences were obtained, where a dose of 4 mg/kg of Ferumoxytol was infused over six minutes. All examinations were performed on either a Siemens 3.0 T Prisma Fit, a Siemens 3.0 T TIM Trio, or a Siemens 1.5 T Avanto MRI scanner. Image post-processing was performed using OsiriX and Vitrea software for endoleak identification and display.Results: Twenty-six FE-MRA examinations were completed, where 24 were fully diagnostic and 2 were limited by metal artifact. Three patients underwent one follow-up examination, while one patient underwent two follow-up examinations. Endoleaks were identified in seven patients: one Type Ia, two Type Ib, and four Type II. The Type Ia endoleak patient received follow-up imaging two years after initial imaging. A Type II endoleak patient received follow-up imaging six months and one year after initial imaging. In both cases, the Type I and Type II endoleaks were reproducibly visualized.

The focus was assessment of the visibility and fusion of the three ossification centers and three synchondroses of the atlas, and six ossification centers and four synchondroses of the axis, based on age.Results: Complete ossification of the anterior arch of the atlas was observed in 60.4 % of patients, increasing with age from 11.1 % in the 0-12 months age group to 97.3 % in the 61-72 months age group. Patency of the ventrolateral synchondrosis of the atlas decreased from 100 % in the 0-12 months age group to around 30 % in the 61-72 months age group. Subdental synchondrosis and neurocentral synchondrosis of the axis were patent in 47.0 % and 50.6 % of patients, respectively, both decreasing with age. The apicodental synchondrosis of the axis remained mostly patent (98.1 %). Overall, there was a trend of decreasing patency in synchondroses and increasing ossification with advancing age.Conclusion: These findings provide a better understanding of normal ossification patterns and timelines, facilitating the accurate distinction between normal variations and traumatic injuries.","PeriodicalId":50680,"journal":{"name":"Clinical Imaging","volume":"118 ","pages":"110395"},"PeriodicalIF":1.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142900168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

LVWT was manually measured in each segment according to the American Heart Association's 17-segment model at end-diastole and mid-diastole. Regional LVWT was calculated as the average value of relevant segments.Results: The study included 187 subjects with a mean age of 51 ± 11 years, including 77 (41 %) men. Global LVWT was lower at end-diastole than at mid-diastole (5.7 ± 0.8 vs. 6.5 ± 0.9 mm, P < 0.001). Each segmental LVWT correlated significantly between end-diastole and mid-diastole (Pearson's correlation coefficient: 0.79-0.87). Segment 2 was thickest (8.1 ± 1.5 mm at end-diastole and 9.1 ± 1.7 mm at mid-diastole). LVWT was greater in men than in women (all P < 0.001). The upper limits of LVWT were 9.9 mm for women and 11.7 mm for men at end-diastole, and 11.8 mm for women and 13.1 mm for men at mid-diastole. LVWT progressively thinned from the base to the apex. Apical LVWT measured on short-axis and long-axis showed a small but statistically significant difference, particularly in Segment 16.Conclusion: This study provides CCT reference values for LVWT at end-diastole and mid-diastole. Mid-diastolic LVWT was slightly greater than end-diastolic LVWT, with a statistically significant difference. Normal LVWT was greater in men than in women, with regional variations observed in both phases.","PeriodicalId":50680,"journal":{"name":"Clinical Imaging","volume":"118 ","pages":"110390"},"PeriodicalIF":1.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142878388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The survey was open for seventeen days in 2023, with a single reminder. Statistical analysis was performed using Pearson Chi square hypothesis testing and logistic regression modeling.Results: Response rate was 19.2 % (599/3112). Of the 588 ABR certified, 65.6 % (n = 386) of respondents participated in ABR MOC, 50.9 % (n = 299) were in TR and 43.4 % (n = 255) were in PP. PP was associated with a greater participation in the ABR MOC program than TR (p0.05). Format (42 %) and content/topic (35 %) were the most important reasons for CME selection. PP radiologists preferred live in person lectures 1.94 times over TR. ABR MOC participants were 1.82 times more likely to select \"cost\" as the most important reason for choosing a Cat-1 CME activity, had lower odds of agreeing that Cat-1 CME helped maintain and improve skills, and had lower odds of being satisfied with Cat-1 CME activities available.Conclusion: TR and PP settings in addition to ABR MOC participation status are associated with differences in Cat-1 CME-related preferences and perspectives.","PeriodicalId":50680,"journal":{"name":"Clinical Imaging","volume":"118 ","pages":"110391"},"PeriodicalIF":1.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142907905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
