The Echogenic Liver: Steatosis and Beyond
Ultrasound is the most common modality used to evaluate the liver. An echogenic liver is defined as increased echogenicity of the liver parenchyma compared with the renal cortex. The prevalence of echogenic liver is approximately 13% to 20%. In most clinical settings, increased liver echogenicity is simply attributed to hepatic steatosis. It is important to recognize other hepatic and systemic diseases including cirrhosis, viral hepatitis, glycogen storage disease, and hemochromatosis that may also cause an echogenic liver and to identify the associated findings to distinguish them from hepatic steatosis.

Sonographic Evaluation of Genitourinary Inflammatory Pseudotumors and Its Mimics
Inflammatory pseudotumor is a relatively rare, nonneoplastic lesion composed of inflammatory cells and myofibroblastic spindle cells that can be identified on sonographic evaluation of the genitourinary system. These lesions are thought to be an inflammatory response to insults such as surgery, trauma, infection, or malignancy. Such lesions need to be distinguished from true neoplasms and other benign lesions, including inflammatory responses and infectious processes. Identification of inflammatory pseudotumors and its mimics is important for radiologists to guide patient treatment and follow-up. This pictorial essay prese...

Clinical Ultrasound Education for Medical Students: Virtual Reality Versus e-Learning, a Randomized Controlled Pilot Trial
The primary aim was to evaluate the effect of immersive virtual reality learning for training medical students in basic clinical ultrasound. Secondary outcomes were to explore if virtual reality learning had an effect on hand-eye coordination skills and if the medical students wanted more virtual reality learning.

Diagnostic Accuracy of Longitudinal Evaluation of Central Nervous System Sonoelastography in Preterm and Term Neonates
The objective of this study was to evaluate the brain elasticity of the central nervous system in preterm and term neonates.
Methods
Seventy-seven healthy preterm and term neonates (mean gestational age [GA], 37.5 weeks; range, 32.6–40.5 weeks) were included in the study. Periventricular and subcortical white matter, cortical gray matter, and ventricle and subdural spaces were examined with strain elastography ratios. Each patient underwent sonography evaluation twice. The mean age at the time of sonographic evaluation was 9 days (range, 4–15 days) for the first evaluation and 37 days (range, 31–47 days) for t...

Automated Segmentation of Fetal Ultrasound Images Using Feature Attention Supervised Network
Segmentation of anatomical structures from ultrasound images requires the expertise of an experienced clinician, but developing a machine automated segmentation process is complicated because of the existence of characteristic artifacts. In this article, we present a novel end-to-end network that enables automated measurements of the fetal head circumference (HC) and fetal abdomen circumference (AC) to be made from 2-dimensional (2D) ultrasound images during each pregnancy trimester. These measurements are necessary, because the HC and AC are used to predict gestational age and to monitor fetal growth. Automated HC and AC ...

Sonographic Evaluation of Pulmonary Interstitial Edema in Patient With Preeclampsia
The aim of this study was to sonographically detect pulmonary edema, which is a major problem in pregnant women with preeclampsia, in the interstitial phase. We evaluated 41 preeclampsia patients and 21 control subjects prospectively. In the preeclampsia group, 26 patients had severe features, whereas the other 15 patients had none. To detect early fluid loading in lungs, sonographic B lines were counted from the intercostal space by using ultrasonography, and left ventricular loading findings were examined for corporation by using transthoracic echocardiography both before and after birth. In severe preeclampsia, the numb...

Pulsatility and Resistance Indices of Uterine and Ovarian Arteries in Anovulatory Women With Polycystic Ovary Syndrome
We aimed to compare the ovarian and uterine artery blood flow of anovulatory patients with polycystic ovary syndrome (PCOS) with those of ovulatory women throughout the menstrual cycle using color Doppler ultrasound. Seventy-one women with PCOS, who were admitted to the infertility outpatient clinic of a training and research hospital, were included in the study. The patients were divided into 2 groups as anovulatory (group 1, n = 23) and ovulatory (group 2, n = 37). Each patient was followed up throughout her menstrual cycle and included in either group 1 or group 2. Anovulatory cycles were determined by consecutive ultra...

Translabial Ultrasound for Assessment of Synthetic Midurethral Sling Complications
This article provides example images of transobturator and retropubic slings and their associated complications, as visualized on TLUS. Accurate imaging and assessment of MUS is helpful in the evaluation of the patient presenting with symptoms suspicious for sling-related complications and in the planning of surgical revision.

Obstructed Defecation Symptom Severity and Degree of Rectal Hypermobility and Folding Detected by Dynamic Ultrasound
We used dynamic pelvic floor ultrasound to investigate the relationship between obstructed defecation symptom (ODS) severity and the degree of rectal hypermobility/folding. In this retrospective study, women who presented with ODS from October 2017 to January 2019 and underwent an interview, pelvic examination, and pelvic floor ultrasound were recruited. Patients were diagnosed with abdominal constipation, dyssynergia, or pelvic constipation. Pelvic constipation patients were categorized based on their reported frequency of incomplete emptying of stool ( (Source: Ultrasound Quarterly)

Sonographic Evaluation of Pelvic Venous Disorders
Pelvic venous disorders are a group of interrelated conditions characterized by venous incompetence. These conditions often manifest with nonspecific symptoms that overlap with many gynecological, gastrointestinal, and urologic diseases. Clinical diagnosis can be difficult, and imaging can play a vital role in differentiating etiology. Sonographic evaluation is often the first step in evaluating these symptoms. Special attention to possible underlying pelvic venous disorders can reveal characteristic findings, support diagnosis, and guide treatment. Here we review pelvic congestion syndrome, nutcracker syndrome, May-Thurne...
