Optimizing the Time for Developmental Dysplasia of the Hip Screening: Earlier or Later?
Conclusions
Late diagnosis of DDH might cause serious public health problems. On the other hand, early US examinations can result in false-positive diagnosis. Unfortunately, there is still confusion about the optimal time for DDH screening with US, especially among radiologists who are not specialized in DDH sonography. A US scan performed at eighth week of life can predict any pathology presence safely and correctly. (Source: Ultrasound Quarterly)

The High-Frequency Ultrasound Detection of Rat Sciatic Nerve in a Crushed Injury Model
Conclusions
High-frequency ultrasound is capable of capturing dynamic changes in rat sciatic nerves in a crushed injury model. This can be used as an auxiliary method of evaluation in traditional peripheral nerve injury experiments. (Source: Ultrasound Quarterly)

Ultrasound Imaging of the Brachial Plexus and Nerves About the Neck
This review describes techniques for sonographic evaluation of the brachial plexus and multiple regional nerve branches in the neck, essential for successful implementation of neurosonology in the neck. High-frequency ultrasound transducers have the ability to produce superior, high-resolution images, allowing for superb depiction of nerve fascicular anatomy. Sonographic appearances of normal nerve anatomy and nerve-specific pathology are reviewed. Benefits and limitations of ultrasound nerve imaging compared with magnetic resonance imaging are discussed.

Ultrasound Combined With Microbubbles Increase the Delivery of Doxorubicin by Reducing the Interstitial Fluid Pressure
In this study, all 48 tumor-bearing rabbits were divided randomly into 6 groups (n = 8 per group). These 6 groups include doxorubicin therapy together with ultrasound combined with microbubble treatment group (Ad-US-MB treatment group), US-MB treatment group, US treatment group, MB treatment group, doxorubicin treatment group (Ad treatment group), and blank control group. The animals were intravenously injected with doxorubicin hydrochloride, and then the tumors of the animals were disposed by low-intensity ultrasound and mirobubbles for 10 minutes. The IFP of tumor tissues in rabbits was detected before and after interven...

Retrospective Analysis of Contrast-enhanced Ultrasonography Effectiveness in Reducing Time to Diagnosis and Imaging-related Expenditures at a Single Large United States County Hospital
Hepatic and renal lesions detected during ultrasound examinations frequently require subsequent contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI) for characterization, delaying time to imaging diagnosis and increasing overall health care expenditures. Contrast-enhanced ultrasonography (CEUS) is a comparatively low-cost diagnostic tool that is underutilized in the evaluation of such indeterminate or suspicious hepatic and renal lesions. A retrospective chart review of CEUS examinations performed in our department demonstrated significantly shorter time to imaging diagnosis with CEUS compared to ...

A Preliminary Comparative Study of Young's Modulus Versus Shear Modulus in the Diagnosis of Breast Cancer
Purpose
The purpose of this study was to compare the diagnostic value of Young's modulus (E) and shear modulus (G) in the differential diagnosis of benign and malignant breast masses using sound touch elastography (STE) and to explore the relationship between G and E in breast lesions.
Methods
A total of 96 consecutive women with 110 pathologically confirmed breast masses were included. All masses were detected by conventional and STE ultrasound. Emean, Emax, Emin, ESD, Gmean, Gmax, Gmin, and GSD were determined and evaluated for evidence of significant differences between benign and malignant breast masses. Receiver ...

A Clinical Study Comparing the Diagnostic Performance of Assist Strain Ratio Against Manual Strain Ratio in Ultrasound Breast Elastography
Conclusion
Assist strain ratio demonstrated similar diagnostic performance compared with MSR. In addition, the coefficient of variation of ASR is lower, implying lower intraoperator dependency. Thus, ASR may aid less-experienced scanners in obtaining improved results. (Source: Ultrasound Quarterly)

Value of Three-Dimensional Ultrasound in Differentiating Malignant From Benign Breast Tumors: A Systematic Review and Meta-Analysis
Currently, the aim of differentiating malignant from benign breast tumors and diagnosing early breast cancer is more accurately fulfilled with the addition of ultrasound (US) scans. Some studies have shown that three-dimensional (3D) imaging opens a new diagnostic window because of a better and more detailed impression of the spatial arrangement of focal breast masses. Therefore, we carried out this study to assess the efficacy of 3D-US diagnostic techniques for the detection of breast cancer using systemic analyses. We searched the MEDLINE, Pubmed, EMBASE, and Cochrane Library for using 3D-US for the diagnosis of breast c...

A Low-Cost Highly Configurable Phantom for Simulation of Imaging-Guided Endocavitary Procedures
We developed a method to create customizable phantoms suitable for endocavitary imaging and interventional research, based on the fabrication of an acrylic phantom mold, and development of a phantom matrix composed of gelatin, agar, graphite particles, and propanol. Our phantom was mechanically stable, easily fabricated, and highly adjustable, and its ultrasound (US) and magnetic resonance imaging (MRI) scans showed the qualification for the procedure guidance compared with the human prostate image using the same US system. To test the feasibility of the phantom for the research, the seeds placement guided by MRI/US fusion...

Accuracy of Physical Examination, Transvaginal Sonography, Magnetic Resonance Imaging, and Rectal Endoscopic Sonography for Preoperative Evaluation of Rectovaginal Endometriosis
The aim of this study was to compare the effectiveness of physical examination, transvaginal sonography, magnetic resonance imaging, and rectal endoscopic sonography for the identification of rectovaginal endometriosis and potential rectal infiltration. Women with suspected rectovaginal endometriosis underwent physical examination, transvaginal sonography, magnetic resonance imaging, and rectal endoscopic sonography. Evaluation was performed for the presence of rectovaginal endometriotic foci and rectal infiltration. The findings obtained with these methods were compared with those of surgical and histopathological examina...

Combination of Sonographic Morphology Score and Tumor Markers for Detecting Postoperative Recurrent Pelvic Ovarian Carcinoma: Compared With MRI Assessment
To assess the efficacy of the combination of sonographic morphology score (SMS) with CA125 and HE4 for detecting recurrent pelvic ovarian carcinoma (OC). Data of 58 OC patients treated in our hospital between 2014 and 2016 were analyzed. After cytoreductive surgery and routine chemotherapy, all patients were followed up by transvaginal ultrasound examination (SMS for pelvic masses based on volume and structure scores) and tumor marker (serum CA125 and HE4) detection. Clinical diagnosis of recurrent OC was based on physical examination, magnetic resonance imaging, and punctured pathology for pelvic masses. Receiver operatin...
