Interobserver Agreement Between Primary Sonographers and Secondary Overreaders for Screening and Surveillance Liver Ultrasounds Using Ultrasound Liver Imaging Reporting and Data System
The authors aim to identify if primary sonographers and secondary reviewers, both radiologists and sonographers, are likely to assign the same Ultrasound Liver Imaging Reporting and Data System (US LI-RADS) scores for liver surveillance ultrasounds. Institutional review board approval was obtained. Sonographers were familiarized with US LI-RADS via radiologist-led lectures. Three sonographers prospectively scored 170 screening examinations using US LI-RADS recommendations. Scans were retrospectively rescored by a fourth sonographer and a radiologist, both of whom were blinded to the original scores. Results were analyzed w...

Contrast-Enhanced Ultrasound as a Problem-Solving Modality: Tips and Tricks
Contrast-enhanced ultrasound (CEUS) continues to be an ever-growing tool in radiation-free imaging. While it has been widely used in cardiac imaging, CEUS has only recently become an Food and Drug Administration–approved and viable modality for evaluation of abdominal structures. Ultrasound contrast agents are nontoxic, microbubble-based vascular agents and can be used to reliably assess enhancement patterns of various lesions in real time. In particular, it's non nephrotoxic nature makes CEUS a particularly important tool in renal failure patients requiring serial follow-up. This review provides a comprehensive discussi...

Evaluation of Diaphragm Thickness and Stiffness Using Ultrasound and Shear-Wave Elastography
The purposes of this study are to measure the thickness and stiffness of diaphragm in association with the respiratory cyclus and to assess the reproducibility of these measurements. Forty individuals who are volunteered for participating diaphragm evaluation were included in the study. Two radiologists with 14 and 15 years of experiences in abdominal ultrasound performed all examinations independently. Furthermore, 8 chronic obstructive pulmonary disease (COPD) patients were examined by only the first radiologist. Gray scale and shear-wave elastography imaging of only the right hemidiaphragm of all participants were perfo...

Ovarian Stiffness Is Significantly Increased in Polycystic Ovary Syndrome and Related With Anti-Mullerian Hormone: A Point Shear Wave Elastography Study
Objectives
Parenchymal stiffness obtained by point shear-wave elastography (pSWE) in solid organs is used as a sign of damage in these organs. However, its clinical use and whether patients with polycystic ovary syndrome (PCOS) have increased ovarian tissue stiffness are still unclear. The aim of this study is to determine the parameters related to ovarian stiffness and whether there is an increase in ovarian stiffness in patients with PCOS compared with healthy controls.
Methods
Forty-five women who were followed up regularly with the diagnosis of PCOS and 30 healthy controls similar to age and sex were include...

Color Doppler Imaging of Vascular Abnormalities of the Uterus
Many uterine abnormalities present clinically with bleeding encompassing a broad spectrum of patients from postmenopausal spotting to life-threatening hemorrhage. Color and spectral Doppler imaging of the pelvis is often the first crucial investigation used to quickly establish the correct etiology of the uterine bleeding and guide clinical decision making and patient management.

Toward Ergonomic Design in Ultrasound Scanning: Strategies to Mitigate Injurious Forces
Sonographers experience stress-related musculoskeletal injuries at alarming rates. The magnitude of the problem has resulted in substantial economic and human costs. Early efforts, such as the transposition of office ergonomic models to the ultrasound suite, have been only marginally successful because of the vast difference between clerical and sonography work demands. In addition, although the issue has attracted the attention of professional sonographer societies, equipment manufacturers, and governmental agencies, such as the OSHA (Occupational Safety and Health), the causative mechanisms by which sonographers are inju...

Thoracic Outlet Syndrome—An Uncommon Cause of Acute Upper-Limb Ischemia
Acute upper-limb ischemia is usually secondary to thromboembolic occlusion. The heart is the usual source of emboli in the majority of patients. In a small percentage of cases, the thromboembolic process may start in a proximal large-sized artery, such as the subclavian artery, resulting in thromboembolic occlusion of the upper extremity's small peripheral arteries. In patients with acute upper-limb ischemia, a systematic color flow Doppler ultrasound of the upper extremity arteries may reveal thoracic outlet syndrome as the underlying cause. This pictorial review presents a systemic color flow Doppler approach to evaluate...

In Vivo Ultrasound Imaging of the Spinal Cord and Subarachnoid Space at the C1-C2 Level in Healthy Adult Subjects
Ultrasound (US) imaging of the spinal canal is applied in early infants before formation of posterior spine bony elements. Here, we demonstrate for the first time in adult healthy subjects that excellent visualization of intrathecal structures at the level of C1-C2 is possible by transcutaneous US in flexion, extension, and neutral head positions through the soft tissue US window between C1-C2. We show with US that the posterior subarachnoid space increases significantly in head extension. Accordingly, C1-C2 US guidance can facilitate cervical myelography. In addition, we suggest that US of the C1-C2 spine level may offer ...

An Exploratory Study Into a New Head Ultrasound Marker for Predicting Neurodevelopmental Outcomes in Preterm Infants
Preterm infants are at risk of neurological impairments and long-term developmental delay. Head ultrasound (HUS) is a promising tool for early detection of preterm brain injury and prediction of neurodevelopmental outcomes. We performed a retrospective analysis of data of 42 preterm infants with neurodevelopmental follow-up at 12 to 24 months corrected age. Corpus callosum length (CC length) and corpus callosum-fastigium length (CCF length) were measured on the HUS scans. Motor function and communication skills were assessed using evaluation scales. Corpus callosum length and CCF length were correlated with neurodevelopmen...

The Wash-Out of Contrast-Enhanced Ultrasound for Evaluation of Hypoxic Ischemic Injury in Neonates and Infants: Preliminary Findings
We evaluated the use of quantitative contrast-enhanced ultrasound (CEUS) to study wash-out behavior of ultrasound contrast agents in the pediatric brain in cases of hypoxic ischemic injury (HII). Six neonates and young infants were imaged using CEUS for suspected HII in the Neonatal Intensive Care Unit/Pediatric Intensive Care Unit. After receiving a bolus of ultrasound contrast agent Lumason (Bracco Diagnostics Inc.), analysis was performed in the whole brain, cortex, cortical/subcortical gray and white matter and central gray nuclei to quantify wash-out metrics and ratios. On magnetic resonance imaging clinical imaging f...
