As TPUS is a common method, it could supplement vaginal palpation and even replace it in certain situations. In addition, we used a 4-dimensional method for the assessment of cervical effacement.Materials and methods: 54 women in labor were included and underwent TPUS. The resulting images from the acquired 4D volumes were evaluated after the examination for the first time and a second time after 21 days. The measured values were cervical length, dilatation and effacement, the angle of progression (AoP), and head-perineum distance.Results: 54 patients were examined. TPUS images were unable to be evaluated in 12 patients because of cervical dilatation of more than 5 cm or poor image quality. Thus, 42 measurements were included. The concordance correlation coefficients according to Lin are satisfactory overall, with one exception for cervical effacement. The accuracy component of cervical length (CCCLin: 0.93; accuracy: 1.00), dilatation (CCCLin: 0.93; accuracy: 1.00), and AoP (CCCLin: 0.87; accuracy: 1.00) is excellent and still high for the head-perineum distance (CCCLin: 0.89; accuracy: 0.96) and cervical effacement (CCCLin: 0.77; accuracy: 0.97).Conclusion: TPUS is a valuable noninvasive tool with good diagnostic accuracy for the AoP, cervical length, and dilatation. Our study provides support for the use of TPUS to complement a vaginal examination. It should not replace a digital examination but should serve as a suitable alternative method for monitoring labor progression in the future.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10603330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Severe conditions such as acute abdomen or hemodynamic instability are mostly related to intra-abdominal blood loss diagnosed as free fluid (FF) on transvaginal sonography (TVS). The aims of the current study were to investigate the value of FF and to assess other potentially predictive parameters for judging urgency.Methods: Retrospective cohort analysis on prospectively collected cases of proven ECP (n = 343). Demographics, clinical and laboratory parameters, and findings on TVS and laparoscopy (LSC) were extracted from the digital patient file. FF on TVS and free blood (FB) in LSC were evaluated. Low urgency was defined as FB (LSC) < 100 ml and high urgency as FB (LSC) ≥ 300 ml. The best subset of variables for the prediction of FB was selected and predictors of urgency were evaluated using receiver operator characteristic (ROC) curves.Results: Clinical symptoms, age, β-HCG, hemoglobin (HB) preoperative, and FF were examined in multivariate analysis for the cutoff values of 100 ml and 300 ml. FF was the only independent predictor for low and high urgency; HB preoperative was only significant for high urgency offering marginal improvement. ROC analysis revealed FF as an excellent discriminatory parameter for defining low (AUC 0.837, 95% CI 0.794-0.879) and high urgency (AUC 0.902, 95 % CI 0.860-0.945).Conclusion: Single assessment of FF on TVS is most valuable for judging urgency. However, the exact cutoff values for a low- and high-risk situation must still be defined.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10603331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although APHE is considered as the hallmark of HCC, it can be absent in some HCCs. Thus, we explored which sonomorphological and histopathological features of HCC are associated with a lack of APHE upon CEUS.Methods: Focal liver lesions in high-risk patients for HCC were assessed with CEUS following a standardized protocol in a prospective multi-center real-life setting. CEUS patterns in HCC were assessed, and tumour and patient characteristics were compared for HCCs with and without APHE.Results: 316 patients with HCC were recruited (cirrhosis, 76.9%). APHE occurred in 271/316 HCCs (85.8%). A lack of APHE was associated with portal vein thrombosis, tumour infiltration of the liver vessels (p<0.001), larger size, multilocularity, and higher depth location upon ultrasound (p<0.01). Histological grading did not differ between HCCs with and without APHE (p=0.39). Histopathological features of HCCs without APHE included cirrhotic stromal reaction, marked tumour cell steatosis and absence of the typical surrounding dilated sinusoidal vascular channels.Conclusion: Correlation with histopathological findings support the fact that HCCs with a lack of APHE in CEUS are a heterogeneous group. The examiner has to be aware that particularly HCCs with portal vein thrombosis or macro-invasion of the liver vessels may lack APHE.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9168966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Volumes were acquired from the transthalamic axial plane by transabdominal ultrasonography and were then post-processed with Crystalvue, Realisticvue rendering software and inversion mode. Volume quality was assessed. The anatomic definition of the sulci and gyri was determined according to location and orientation. The morphology alteration and sulcus display rates were recorded in sequential order of gestational weeks.

The morphology of the sulci and gyri on the brain convex surface could be demonstrated clearly on 3D-ICRV images. The Sylvian fissure was the first structure to be recognized.

Materials and Methods Imaging data from 112 patients from 12/2003 to 10/2022 with histologically confirmed Hodgkin lymphoma during staging or relapse were analyzed for splenic lymphoma involvement. In all patients, standard imaging (CT/PET-CT), along with B-mode US and CEUS examinations, was performed. Evidence of focal splenic lesions (FSLs) found by imaging procedures was suggestive of splenic involvement. Follow-up imaging was performed in each patient after treatment, and treatment response indicated definitive splenic involvement. Results 40 patients (35.7%) were identified by imaging modalities as having splenic involvement, which was confirmed by response during follow-up. Standard CT/PET-CT imaging detected splenic involvement in 36/112 patients (32.1%). FSLs were detected with B-mode US in 38 patients (33.9%) and CEUS in 36 patients (32.1%). The sensitivity of standard imaging, B-mode US, and CEUS was 90%, 95%, and 90%, respectively. Conclusion B-mode US examination is a diagnostic method used in addition to standard imaging for the detection of splenic involvement in Hodgkin lymphoma. CEUS does not provide additional benefit compared to B-mode US and the standard reference procedure.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49684179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
