Measurements of fetal atrial size, shape, and contractility have been previously reported using the TomTec fetal heart speckle tracking analysis software, which currently is no longer available in the marketplace. At the present time, the only software available for speckle-tracking analysis of the fetal heart is fetalHQ, which analyzes the fetal heart ventricles using the same algorithms as the TomTec software used for speckle-tracking analysis. This communication will review how to use the fetalHQ software to measure the size, shape, and contractility of the atrial chambers.

The phenomenon of intrarenal reflux (IRR) has been considered a crucial link between vesicoureteral reflux (VUR) and segmental scarring. We conducted a study on renal length in 104 children diagnosed with Grades III–V VUR, with or without IRR, using contrast-enhanced voiding urosonography (ceVUS). The patients were divided into two treatment groups: the conservative antibiotic prophylaxis (CAP) group and the operation group, which were further categorized into two subgroups: the IRR group and the non-IRR group. Our findings revealed an incidence rate of 35.96% (41/114) for IRR occurrence, with 43.42% (33/76) occurring in upper renal segments, 32.89% (25/76) in lower segments, and 23.68% (18/76) in middle segments. In the CAP group where the effects of IRR persisted, the renal growth observed was as follows: IRR group—0.19 ± 0.13 cm; non-IRR group—0.39 ± 0.23 cm; contralateral negative group—0.66 ± 0.35 cm; control group—0.46 ± 0 .25 cm respectively (P < .05). In the operation group, where the effects of IRR were eliminated, the renal growth for the IRR group, non-IRR group, contralateral negative group, and control group was 0.46 ± 0.22 cm, 0.54 ± 0.31 cm, 0.67 ± 0 .42 cm, and 0.36 ± 0.17 cm respectively (P < .005). In conclusion, the presence of IRR can impact renal growth in children diagnosed with Grades III–V primary VUR. Following surgical intervention, the IRR kidney does not exhibit catch-up growth; however, it demonstrates parallel growth alongside the unaffected kidney. Conversely, the non-IRR kidney experiences catch-up growth. Therefore, for children presenting with Grades III–V primary VUR combined with IRR, a more aggressive treatment approach such as surgery is recommended.

Objectives
Although serum screening for aneuploidies has become less prevalent, maternal-serum alpha-fetoprotein (MSAFP) screening for body-wall defects remains widespread. We explored whether MSAFP screening is associated with earlier omphalocele detection than ultrasound alone.
Methods
This is a retrospective cohort study of prenatally detected omphalocele cases at our center from 2007 to 2023. We explored the association between MSAFP screening, gestational age at omphalocele detection, and clinical outcomes.
Results
Among 101 pregnancies with prenatally diagnosed omphalocele, 27 (26.7%) had MSAFP screening. The median gestational age at MSAFP screening was 17 weeks 4 days. Of those who received MSAFP screening, 11 (41%) had values ≥2.5 multiples of the median (MoM) and 16 (59%) were not elevated. MSAFP results did not correlate with omphalocele size and were not associated with prenatal or postnatal outcomes. MSAFP screening did not result in earlier suspicion for or confirmation of omphalocele (P = .97 and P = .87, respectively). In contrast, first-trimester ultrasound screening was associated with earlier suspicion for and confirmation of omphalocele (P < .01 and P = .01, respectively). There were no clinical or demographic differences between those who received MSAFP screening and those who did not (including body mass index or commute distance to an urban center).
Conclusion
MSAFP screening is not associated with earlier omphalocele detection. Furthermore, in pregnancies with prenatally diagnosed omphalocele, the results of MSAFP screening are not predictive of clinical outcomes.

Purpose
Posthepatectomy liver failure (PHLF) is a major cause of postoperative mortality in hepatocellular carcinoma (HCC) patients. The study aimed to develop a method based on the two-dimensional shear wave elastography and clinical data to evaluate the risk of PHLF in HCC patients with chronic hepatitis B.
Methods
This multicenter study proposed a deep learning model (PHLF-Net) incorporating dual-modal ultrasound features and clinical indicators to predict the PHLF risk. The datasets were divided into a training cohort, an internal validation cohort, an internal independent testing cohort, and three external independent testing cohorts. Based on ResNet50 pretrained on ImageNet, PHLF-Net used a progressive training strategy with images of varying granularity and incorporated conventional B-mode and elastography images and clinical indicators related to liver reserve function.
Results
In total, 532 HCC patients who underwent hepatectomy at five hospitals were enrolled. PHLF occurred in 147 patients (27.6%, 147/532). The PHLF-Net combining dual-modal ultrasound and clinical indicators demonstrated high effectiveness for predicting PHLF, with AUCs of 0.957 and 0.923 in the internal validation and testing sets, and AUCs of 0.950, 0.860, and 1.000 in the other three independent external testing sets. The performance of PHLF-Net outperformed models of single- and dual-modal US.
Conclusions
Preoperative ultrasound imaging combining clinical indicators can effectively predict the PHLF probability in patients with HCC. In the internal and external validation sets, PHLF-Net demonstrated its usefulness in predicting PHLF.

To determine whether superb microvascular imaging (SMI) provides a more precise delineation between reversible and irreversible stages of uncomplicated acute appendicitis managed non-operatively.
Methods
This prospective clinical study examined pediatric patients with acute appendicitis initially treated non-operatively and evaluated using power Doppler (PD) and SMI. We determined case severity, monitor appendiceal blood flow (BF), and appendicitis reversibility. Complicated cases were excluded. Severity was classified using B-mode as well as PD, or SMI: Grade I, smooth wall/normal BF; Grade IIa, irregular wall/increased BF; Grade IIb, irregular wall/decreased BF; and Grade III, absence of wall/loss of BF.
Results
This study examined a total of 100 patients with acute appendicitis, after excluding 29 patients. All 10 patients with normal BF on PD (Grade I) showed similar BF on SMI (Grade I). Among 29 patients with increased BF on PD (Grade IIa), corresponding increased BF was noted on SMI (Grade IIa), and all these patients showed full recovery. Of the 55 patients showing decreased BF on PD (Grade IIb), 52 showed increased BF on SMI (Grade IIa). The remaining three patients, identified with an impacted appendicolith, showed decreased BF on SMI (Grade IIb) and experienced treatment failure, subsequently developing abscesses. In all six patients with undetectable BF on PD (Grade III), SMI similarly could not detect appendiceal BF (Grade III), and non-operative management failed for these patients.
Conclusions
SMI offers an objective and effective means of delineating the threshold between reversible and irreversible stages in uncomplicated acute appendicitis following non-operative management.

Objectives
Updated retrospective review of the sonographic appearance of palmar fibromatosis (PF) with evaluation of the utility of the Comb Sign previously described in plantar fibromas. Additional evaluation was conducted on the location relative to the flexor tendon, anatomic proximity of palmar fibromas to the A1 pulley and evaluate any potential association with trigger finger.
Methods
Medical record and imaging review was performed from 2017 to 2023, for patients with a new onset ultrasound or clinical diagnosis of PF. Clinical associations and imaging morphology were reviewed including presence of the Comb Sign, fibroma association with the A1 pulley, and fibroma association with trigger finger.
Results
Exactly 87 total fibromas in 53 patients were evaluated. The Comb Sign was present in 39% of fibromas, usually seen in transverse plane, more prevalent in multifocal disease and larger fibromas. Most (72%) palmar fibromas were within 1 cm of, contacted, or covered the A1 pulley (P < .001). Lateral extension beyond the flexor tendon axis can be seen (44%). Trigger finger and tenosynovitis were rare. However, volume and SI dimension of fibromas were associated with tenosynovitis (P < .0001) and all nine patients with concomitant trigger finger had fibromas within 1 cm from the A1 pulley.
Conclusions
The Comb Sign can aid in sonographic diagnosis of PF. Lateral extension of fibromas can occur. Most palmar fibromas have a significant intimate association with the A1 pulley, and presence of trigger finger with adjacent palmar fibroma can exist and is important for hand surgeons to know preoperatively.

Spondyloarthritis (SpA) is a prevalent genetic disorder that significantly impairs mobility, particularly in the spine, sacroiliac, and peripheral joints. Recent evidence highlights early involvement of the sternoclavicular joint in SpA, which may serve as an initial indicator. Diagnosis often relies on CT and MRI, neglecting ultrasound's potential in identifying SpA-related sternoclavicular arthritis. This review focuses on the joint's anatomy, exploring ultrasound's diagnostic and therapeutic role in SpA-related sternoclavicular arthritis, aiming to provide insights for future ultrasound applications in SpA management.

Objectives
Point-of-care-ultrasound (POCUS) is increasingly used by pediatric emergency medicine (PEM) fellows, but scant data exists on the accuracy of exam interpretations. Our goal was to determine whether agreement on exam interpretation between quality assurance (QA) faculty (reference standard) and PEM fellows varied by fellowship year or exam type.
Methods
Retrospective review of fellow-performed POCUS exams between January 2019 and June 2022. Negative binomial (NB) random effects regression was used to account for longitudinal measurement of individual fellow performance across 3 years. Fixed effects were exam type and fellowship year. To assess between- and within-user variability across time, a random intercept and slope were included for each fellow.
Results
Exactly 3032 exams, performed by 24 fellows, were included. Raw proportion agreement by fellowship year was high for all exam types (≥88%). From the NB model, there was no statistically significant effect of fellowship year on the mean count of agreement. The relative risk (RR) of agreement for exam types was greatest for cardiac vs other types. The standard deviations for the random intercept and random slope were 0.09 and 0.04, respectively, with a correlation of −0.94.
Conclusions
PEM fellows generally interpret exams correctly, with little variation through fellowship, although those who began with more basic skills showed more progress over time. Fellowship year did not influence the likelihood of correct interpretation but there was variation across exam type, with the best agreement for cardiac exams. The extent to which disagreements between fellows and QA faculty represent clinically significant errors requires further study.

Existing automated software for vascular ultrasound data extraction lacks free, open-source options suitable for professionals without coding experience. These programs typically include signal-cleaning algorithms, resulting in processed output without access to raw data. To address these needs, we developed TG Vascutrack, an open-source and user-friendly software tailored for non-coder professionals. It features a graphical interface, multiple functionalities, and provides access to raw data. Comparative analysis against validated software and manual extraction revealed minimal biases and standard deviations in diameter and velocity measurements. TG Vascutrack offers a free, promising solution for non-coders needing automated vascular ultrasound data extraction.
