A Comparison Study of Conventional Ultrasound and Ultrasound Strain Elastography in the Evaluation of Myopathy
The aim of this study was to compare ultrasound strain elastography (USE) with conventional ultrasonography echogenicity (EL) in detecting muscle pathology. For conventional ultrasonography, biceps EL was obtained. For USE, elasticity index (EI) of biceps was represented as a range, from 0 (softest) to 6 (hardest). Muscle-to-fats elasticity ratio compared EI of muscle with that of surrounding fats. Color distribution of elastogram was analyzed using open-source ImageJ software showing % red, % green, and % blue within a region of interest. Increased biceps EL, decreased biceps EI, and elasticity ratio were observed in pati...

Size of the Tonsil on Ultrasound in Children Without Tonsil-Associated Symptoms
This study was performed to establish the reference for tonsil size in children, including neonates, without tonsil-associated symptoms, in relation to anthropometric indices (sex/age/height/weight/body mass index).
We evaluated the size of both tonsils in 362 children by ultrasonography. Tonsil size was calculated as 0.523abc (a, transverse diameter on the transverse image; b, longitudinal diameter on the transverse image; c, longitudinal diameter on the longitudinal image) and compared between each age year using the Wilcoxon signed rank sum test with Bonferroni correction. We evaluated the relationships between tonsil ...

Renal Hemodynamic Changes and Postsurgical Recovery in Children Treated for Ureteropelvic Junction Obstruction
Conclusions
Peak systolic velocity and RI were correlated with renal function and renal parenchymal thickness but were not correlated with dilatation of the renal pelvis. Peak systolic velocity increased whereas RI decreased after surgery and were stable at 8 weeks, but remained abnormal 16 weeks after surgery. Hemodynamic measurements may be a useful and convenient method to evaluate surgical outcomes after Anderson–Hynes pyeloplasty. (Source: Ultrasound Quarterly)

Thyroid Image Reporting and Data System Categorization: Effectiveness in Pediatric Thyroid Nodule Assessment
Ultrasonography (US) is the main imaging method to assess thyroid nodules. In the pediatric population, thyroid nodules are less prevalently seen than those in adults. However, approximately 25% of the nodules can be malignant. Validation of Thyroid Image Reporting and Data System (TI-RADS) classification has been mostly tested in adults, and information on pediatric cases is limited. In the current study, we aim to define the diagnostic power of the TI-RADS risk stratification method in pediatric thyroid nodules.
The study population consists of 68 nodules of 64 patients (20 malignant, 48 benign). We have included patien...

Spectral Doppler Ultrasound Can Help Diagnose Children With Hepatic Sinusoidal Obstructive Syndrome After Hematopoietic Stem Cell Transplantation
Conclusion
Several ultrasound variables can be used as predictors for a patient's risk of developing SOS. The strongest predictors are ascites severity, main portal vein velocity, common hepatic artery peak systolic velocity, and left hepatic artery peak systolic velocity. (Source: Ultrasound Quarterly)

Dynamic Compression—A New and Practical Technique for the Sonographic Diagnosis of Enteric Duplication
Conclusions
The 5-layer sign and peristalsis were not sensitive for enteric duplication. The split-wall sign may have the highest sensitivity and specificity for enteric duplication, but finding this sign is technically difficult and interpretation is complicated by atypical variations. Dynamic compression differentiated enteric duplication from other abdominal cysts with 82% accuracy, and this technique was simple to perform and easier to interpret than the split-wall sign.

Ultrasound Features of Uterine Sarcomas
Uterine sarcomas include leiomyosarcoma, smooth muscle tumor of uncertain malignant potential, endometrial stromal sarcoma, undifferentiated sarcoma, carcinosarcoma, adenosarcoma, and rhabdomyosarcoma. Leiomyosarcomas are the most common uterine sarcomas and list some potential others. Uterine sarcomas have a wide histopathological spectrum that may display various imaging features, making the preoperative diagnosis challenging. The purpose of this review was to discuss the clinical features of uterine sarcomas, as well as their imaging appearances and characteristics. From this, practitioners can ensure that suspicious so...

The Sonographic Spectrum of Pelvic Endometriosis: Pearls, Pitfalls, and Mimics
Endometriosis is a common disease of reproductive-age women that is often first encountered with ultrasound. Therefore, familiarity with the variety of manifestations of endometriosis is important for appropriate diagnosis and management. The aim of this article is to review the spectrum of appearance of pelvic endometriosis and to discuss potential mimics on ultrasound. Given that magnetic resonance imaging is an important problem-solving tool in female pelvic imaging, magnetic resonance imaging correlation is also provided. (Source: Ultrasound Quarterly)

Diagnostic Performance of Doppler Ultrasonography for the Detection of Fetal Anemia: A Meta-analysis
This study evaluates the diagnostic performance of Doppler ultrasound in diagnosing fetal anemia. Data were taken from relevant study reports published in peer-reviewed journals identified after a literature search in electronic databases. Random effects meta-analyses were performed by pooling the effect sizes of diagnostic indices (sensitivity, specificity, positive/negative predictive values, and false-positive rate) or correlation coefficients reported by individual studies. As a result, 31 studies (1848 pregnancies; gestation age, 28.25 weeks [95% confidence interval {CI}, 26.87–29.63]) were included in the meta-anal...

Prediabetes Is Associated With Increased Liver Stiffness Identified by Noninvasive Liver Fibrosis Assessment: ElastPQ Ultrasound Shear Wave Elastography Study
This study was undertaken to determine the incidence of LF and associated parameters in prediabetic patients. Three study groups with equal number of participants defined on the basis of glucose metabolism status were included the following: normal glucose metabolism (NGM), prediabetes, and newly diagnosed type 2 DM (55 patients in each group). Liver stiffness measurements were carried out using liver elastography point quantification, and 7 kPa or greater was considered to denote the presence of LF. Patients were subdivided into 2 groups as those with or without LF. Of the NGM, prediabetes, and type 2 DM subjects involved...

The Value of Superb Microvascular Imaging in Detecting Hepatic Artery Occlusion in Liver Transplantation: A Preliminary Study
Superb microvascular imaging (SMI) is an innovative color Doppler technique that is used to evaluate low-velocity blood flow in particular. Our purpose in this study was to examine the sensitivity and specificity of SMI for assessing occlusion of the hepatic artery after liver transplantation. Ninety-five prospective patients who underwent liver transplantation were included in our study between April 2014 and February 2018. The patients were assessed with color power Doppler sonography and SMI method examinations in this study. Those who were suspected of having hepatic artery occlusion were assessed with computed tomogra...
