Multimodality Imaging Findings of Metaplastic Breast Carcinomas: A Report of Five Cases
In this study, we reviewed data of 5 patients with histopathologically proven metaplastic breast carcinoma. Multimodality imaging findings including those from mammography, ultrasonography, magnetic resonance imaging, and positron emission tomography–computed tomography were recorded.
The results indicated that metaplastic carcinomas tend to show more benign imaging features such as round or oval shape with circumscribed margins and less axillary lymph node metastasis compared with invasive ductal carcinoma. High signal intensity on T2-weighted magnetic resonance imaging due to its cystic or necrotic component may be us...

Early Response Assessed by Contrast-Enhanced Ultrasound in Breast Cancer Patients Undergoing Neoadjuvant Chemotherapy
The study was aimed to investigate the role of contrast-enhanced ultrasound (CEUS) in evaluating the response of patients with breast cancer after receiving neoadjuvant chemotherapy (NAC). A systematic search was conducted in PubMed, Spring, Wanfang, and CNKI databases from 1923 to December 2016. Based on fixed effect model or randomized effects model, standardized mean difference (SMD) with its 95% confidence interval (95% CI) was calculated in accordance with heterogeneity analysis. Cochran Q and I2 tests were used to measure heterogeneity. Sensitivity analysis was performed to evaluate the strength of the meta-analysis....

A Single-Center Retrospective Validation Study of the American College of Radiology Thyroid Imaging Reporting and Data System
This study aimed to evaluate a new risk stratification system, the American College of Radiology (ACR) Thyroid Imaging Reporting and Data System (TI-RADS), published in 2017.
Materials and Methods
From January 2015 to December 2016, 1033 thyroid nodules in 1013 patients who had undergone sonography and thyroid surgery or fine-needle aspiration (FNA) in our hospital were included. The sonographic features were described in a standard manner and analyzed according to the white paper of the ACR TI-RADS Committee. Nodules were assigned points for each feature, and the points were totaled to determine the final TI-RADS level...

Superb Microvascular Imaging of Palatine Tonsils in Healthy Children: A Preliminary Study
In healthy children, the normal vascularity index (VI) values were defined for palatine tonsils using the superb microvascular imaging (SMI), and the relationship with potential factors affecting these values was assessed. This prospective study evaluated 74 children (age range = 3–17 years, median = 13 years, SD = 6.4 years). The cases were divided into 3 subgroups based on age as 3 to 6 years (preschool), 7 to 12 years (school age), and 13 to 17 years (adolescent). Demographic data such as sex, age, and body mass index (BMI) were recorded. The VI values of tonsils were measured with SMI and power Doppler (PD), and the ...

Sonographic Features of Cervical Lymph Nodes in Patients With Hashimoto Thyroiditis and the Impacts From the Levothyroxine With Prednisone Therapy
This study aimed to evaluate the ultrasonographic pattern of cervical lymph nodes (CLNs) and whether levothyroxine with prednisone therapy is effective for lymphadenopathy in patients with Hashimoto thyroiditis (HT).
Methods
This retrospective study was looking at patients with confirmed diagnosis of HT who underwent comprehensive neck ultrasound examination. We reviewed sonographic findings in 127 patients with HT, 234 euthyroid patients with goiter, and 122 healthy subjects. In addition, 30 untreated HT patients with cervical lymphadenopathy were recruited for the levothyroxine with prednisone therapy. We rescanned th...

Shear Wave Elastography Improves Specificity of Ultrasound for Parotid Nodules
This study aimed to determine the performance of Virtual Touch tissue quantification (VTQ) technique in the differential evaluation of parotid gland nodules.
Methods
Acoustic radiation force impulse VTQ technique was used to determine the shear wave velocity (SWV) of 76 patients with parotid nodules and 30 subjects with normal parotid gland. These nodules were assigned to benign and malignant nodules according to histopathology, measurements of SWV were compared, a cutoff point for benign and malignant nodules was obtained with reference to receiver-operating characteristic curve, and relevant sensitivity and specificit...

Quantitative Assessment of Thyroid, Submandibular, and Parotid Glands Elasticity With Shear-Wave Elastography in Children
This study provided the baseline quantitative elasticity measures of thyroid, submandibular, and parotid glands, which would be a reference for upcoming studies. In addition, an increase in elasticity value in thyroid gland as a function of age independent of change in weight and height was demonstrated. (Source: Ultrasound Quarterly)

The Role of Real-Time Sonoelastography in the Differentiation of Benign From Malignant Parotid Gland Tumors
Conclusions
There was a statistically significant difference between benign lesions and malignant lesions in both elastography score and SR. It is possible that elastography can improve the noninvasive diagnostic accuracy for certain pathological conditions. (Source: Ultrasound Quarterly)

Clinical Application of Real-Time Shear Wave Elastography in Identifying the Histological Components of Parotid Adenolymphoma
This study aimed to investigate the relationship between the elastic modulus and the histological components of parotid adenolymphoma by using real-time shear wave elastography.
Methods
A total of 157 patients, histologically confirmed as having parotid adenolymphoma, were enrolled in the study. The maximum and the mean elastic modulus of the parotid mass were measured by using preoperative shear wave elastography. Parotid adenolymphoma was histopathologically subdivided into different types based on the relative proportion of stromal to cellular components.
Results
The maximal elasticity of parotid adenolymphoma ran...

Supporting Our Team Through Creating Awareness: The Society of Radiologists in Ultrasound Sonographer Relations Committee Response to the 2016 Society of Diagnostic Medical Sonography Consensus Conference on Work Related Musculoskeletal Disorders
Musculoskeletal injuries have been and remain a significant issue for sonographers. Despite its importance, the topic of musculoskeletal injury in sonographers has received little attention in the radiology literature. Our goal is to bring this extremely important issue to the forefront, with the hope of initiating conversations and actions leading to improved workplace practices for sonographers.

Fetal Splenomegaly: A Review
We report a case of prenatal splenomegaly diagnosed at 35 weeks, confirmed in the postnatal period. The postnatal workup showed the newborn had a familial type 3 form of hemophagocytic lymphohistiocytosis (HLH).
Hemophagocytic lymphohistiocytosis is an aggressive and life-threatening syndrome of excessive immune activation. The genes implicated in the hereditary forms of the disease act in an autosomal recessive fashion. (Source: Ultrasound Quarterly)

Improving Ultrasound Detection of Uterine Adenomyosis Through Computational Texture Analysis
The purpose of our study was to determine if a textural analysis metric can be implemented to improve diagnosis of adenomyosis by ultrasound.
We retrospectively identified 38 patients with a magnetic resonance imaging (MRI) diagnosis of uterine adenomyosis that also had a pelvic ultrasound within 6 months. We also identified 50 normal pelvic ultrasound examinations confirmed by a normal pelvic MRI within 6 months as a control group. A region of interest (ROI) was subsequently placed on the study population ultrasound image corresponding to the area of adenomyosis on MRI. An ROI was placed in the area of the junctional zon...
