Point-of-care (POC) ultrasound refers to the use of portable imaging. Although POC ultrasound is widely available to the neonatologists in Australia and Europe, neonatologists in the United States report limited availability. Our objective was to seek the US neonatologists' perception of barriers and prerequisites in adopting POC ultrasound in neonatal intensive care units. An online survey link was sent via e-mail to 3000 neonatologists included in the database maintained by the American Academy of Pediatrics...

Our goal was to evaluate the role of ultrasound (US) imaging in an experimental 2-hit steatofibrosis rat model. Nineteen female Sprague-Dawley rats were divided into 2 groups: control group (n = 6) and high-fat diet carbontetrachloride (HFD-CCl4) group (n = 13) that was fed with HFD for 14 weeks. Ultrasound was performed to evaluate liver steatosis. The HFD-CCl4 group rats were divided further into 2 subgroups: HFD rats with liver steatosis [US (+) group; n = 6] and without steatosis [US (-) group; n = 7]. All rats in the subgroups were administered with CCl4...

PURPOSE: The aim was to determine the discrepancy rate between the preliminary interpretation by sonographers and the final radiology interpretation for biliary sonographic findings. MATERIALS AND METHODS: Institutional review board approval was obtained. Four hundred consecutive right upper quadrant sonographer performed ultrasounds were reviewed retrospectively. Sonographers' worksheets were compared with the final radiology report. For the purposes of this project, only the biliary findings were compared and reviewed...

Malak Itani, Theodore J Dubinsky
Despite the overwhelming prevalence of cholelithiasis, many health care professionals are not familiar with the basic pathophysiology of gallstone formation. This article provides an overview of the biochemical pathways related to bile, with a focus on the physical chemistry of bile. We describe the important factors in bile synthesis and secretion that affect the composition of bile and consequently its liquid state. Within this biochemical background lies the foundation for understanding the clinical and sonographic manifestation of cholelithiasis, including the pathophysiology of cholesterol crystallization, gallbladder sludge, and gallstones...

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare disorder characterized by aplasia or hypoplasia of the uterus and vagina due to arrest in the development of the müllerian ducts. Women with this syndrome have the normal 46 XX karyotype, normal female secondary sex characteristics, and primary amenorrhea. Only a few cases have been described in the literature where a fibroid develops from a rudimentary, nonfunctioning uterus in patients with MRKH syndrome. In even rarer instances, a fibroid can develop in patients with a congenitally absent uterus...

Jieun Koh, Eun-Kyung Kim, Min Jung Kim, Jung Hyun Yoon, Hee Jung Moon
PURPOSE: The aim of the study was to compare the performances of second-look digital breast tomosynthesis (DBT) and ultrasonography (US) for additional magnetic resonance imaging (MRI)-detected suspicious lesions in patients referred for breast cancer. METHODS: Fifty-five patients (52.5 [9.3] years) with breast cancers newly diagnosed at a referring hospital underwent MRI and afterward DBT and US in our institution. The frequency for detecting additional MRI-detected suspicious lesions on DBT and US and performances of DBT and US were compared...

BACKGROUND: Fetal weight estimation is one of the most important aspects of antenatal care. The effects of amniotic fluid volume on the accuracy of estimated fetal weight (EFW) depend on the amount of fluid, in particular whether it is polyhydramnios or oligohydramnios. Previous studies have reported conflicting results of the effects of amniotic fluid volume on EFW accuracy. AIM: The aim of the study was to evaluate the effects of isolated oligohydramnios cases and polyhydramnios on the accuracy of EFW...

PURPOSE: Our purpose is to determine the efficacy of ultrasound (US), with the addition of contrast enhancement (CEUS), in the identification and characterization of abdominal pathology compared with nonenhanced computed tomography (CT) scan (NECT). METHODS: This prospective cohort study recruited 197 patients with NECT, the majority with renal failure, to have US, with addition of CEUS, if focal pathology was detected, occurring in 145 patients. Nonenhanced CT scan, US, and CEUS images/video files were presented to 2 blinded readers, in anonymous order...

A 12-year-old girl was referred to our radiology department with a rapidly enlarging mass in the right breast. Fine-needle aspiration cytology was suggestive of fibroadenoma. Total excision of the mass was done, and diagnosis was confirmed by histopathology.

Anorectal malformations are a rare condition difficult to diagnose in the prenatal period. It can be suspected if distal bowel appears dilated in the first-trimester ultrasound or if intraluminal echogenic foci are detected during the second-trimester scan. We report a case with these ultrasound signs (dilated sigmoid at the first trimester and intraluminal echogenic calcifications at the second trimester), in which a vesicorectal fistula image was obtained. This is the first published prenatal image of a vesicorectal fistula...

Primary angiosarcoma of the breast is a rare entity. In this case report, we present a case of primary angiosarcoma of the breast in a young woman who presents with her entire right breast enlarged without skin coloration change or signs of mastitis. She recently stopped breastfeeding. This case report will review the literature and present the mammographic and sonographic findings including elastography.

Axillary lymph node (ALN) status is an important prognostic factor for overall breast cancer survival. In current clinical practice, ALN status is evaluated before surgery via multimodal imaging and physical examination. Mammography is typically suboptimal for complete ALN evaluation. Currently, ultrasonography is widely used to evaluate ALN status; nonetheless, results may vary according to operator. Ultrasonography is the primary imaging modality for evaluating ALN status. Other imaging modalities including contrast-enhanced magnetic resonance imaging, computed tomography, and positron emission tomography/computed tomography can play additional roles in axillary nodal staging...

Postoperative spindle cell nodule (PSCN) is a very rare pathologic complication that can occur in association with a recent core needle biopsy, surgery, or trauma. Cases of PSCN have been reported in the lower genitourinary tract, endometrium, and thyroid but are rare in the breast. Herein, we report an ultrasound-guided biopsy-proven PSCN after ultrasound-guided vacuum-assisted excision in the breast.

Tal Cohen, Richard G Barr
There are multiple factors that affect the shear wave speed in the assessment of liver stiffness. In this case report, we present a case of hemochromatosis that has elevated liver stiffness suggestive of significant fibrosis or cirrhosis; however on liver biopsy, no fibrosis was identified. This article will discuss the possibility that liver iron deposition may affect SWE measurements of the liver, leading to inaccurate assessment of liver fibrosis. In these cases, a liver biopsy may be required for accurate liver assessment...
