All radiology residents were surveyed at the start of the academic year to assess prior experience and comfort with ultrasound scanning. First-year residents were surveyed a second time upon course completion.Presurvey and postsurvey responses suggest that participation in the 2-week ultrasound scanning course contributed to an improvement in perceived scanning knowledge and comfort for participating residents. Based on our initial experience, the scanning curriculum presented here provides a comprehensive introductory course for first-year radiology residents both for ultrasound anatomy and for scanning technique. Continued education in hands-on ultrasound skills is a crucial factor in maintaining radiology's dominance in the modality.Our main objective was to evaluate the ophthalmic artery Doppler behavior in twin pregnancies and compare with singleton pregnancies. We studied 64 healthy twin pregnant women between 12 to 38 weeks of gestation. Resistance index (RI), pulsatility index (PI), and peak ratio (PR) were determined. The control group consisted of 289 singletons. Linear regression analysis was performed to evaluate the association between gestational age and the ophthalmic indexes. Student t test was used to compare the means and standard deviation of the Doppler indexes. There was a decrease in RI and PI and an increase in PR with advancing gestational age (ρ less then 0.0001, 0.0052, and 0.0033). The means ± SDs for RI, PI, and PR were 0.77 ± 0.07, 1.79 ± 0.46, and 0.53 ± 0.12, in women with twin pregnancies and 0.75 ± 0.05, 1.88 ± 0.43, and 0.52 ± 0.10 in singletons. CP-868596 No significant difference was found between the PI and PR values, but significant difference was found in the RI values between the groups (P = 0.0332). We concluded that there are no significant differences in ophthalmic artery behavior in twins and the same reference values established in singleton pregnancies can be applied for PI and PR indexes in the evaluation of twin pregnancies. These indexes were the best to evaluate twin pregnancies.With the increasing rate of twin pregnancies due to increase in maternal age and use of assisted reproduction, it is important to be aware of unique diseases which occur specifically to twin pregnancies, especially in monochorionic twin pregnancies. These entities include twin to twin transfusion syndrome, twin anemia polycythemia sequence, twin reversed arterial perfusion, cotwin demise, and conjoined twins. Early evaluation and documentation are imperative to guide management which ultimately leads to better patient outcomes.Right aortic arch anomalies are a spectrum of malformations that include right aortic arch with mirror image branching, right aortic arch with an aberrant left subclavian artery, and double aortic arch. Although these are rare anomalies, they are of importance as they form vascular rings, which can cause symptoms in the newborn period. These anomalies are not detected with routine cardiac views, and it is only with the 3-vessel, and the 3-vessel tracheal view that they can be identified and characterized. We describe specific sonographic findings of these anomalies on the 3-vessel and the 3-vessel tracheal view.Contrast-enhanced ultrasound can be used effectively to evaluate focal hepatic lesions and offers unique advantages over computed tomography and magnetic resonance imaging. Serial vascular filling patterns of focal hepatic lesions during arterial, portal, and late phases can provide unique information on lesion characterization and differentiation. Sensitive depiction of arterial hypervascularity and analysis of washout pattern are clues for differentiation of several indeterminate hepatic nodules on conventional ultrasound and computed tomography/magnetic resonance. In this report, we present cases demonstrating clinical applications of contrast-enhanced ultrasound in the diagnosis and management of focal hepatic lesions.Transarterial chemoembolization (TACE) of hepatocellular carcinoma (HCC) often requires retreatment and identification of feeding vessels supplying the residual/recurrent tumor is an important step in treatment planning. The objective of this study was to determine if contrast-enhanced ultrasound (CEUS) could correctly identify the vessel supplying the residual tumor. To date, 69 patients have undergone CEUS follow-up of HCC TACE therapy at our institution as part of an ongoing institutional review board approved trial (NCT02764801). The CEUS examinations were performed before HCC TACE as well as 1 to 2 weeks and 1 month after treatment using a Logiq E9 scanner with a C1-6 curved array transducer (GE Healthcare, Waukesha, WI). The CEUS images obtained 2 weeks after initial TACE treatment were reviewed, and any feeding vessels supplying the residual HCC were identified. link2 Digital subtraction angiograms during the retreatment TACE were used as reference standard for feeding vessel identification. link3 Thirteen patients with viable HCC post-TACE were included in this study. In these cases, the sonographer correctly identified 85% (11 of 13) of the feeding vessels later confirmed by angiography. Importantly, one of the false-negative cases involved a segment 8 tumor with parasitic blood supply from the medial left hepatic artery. In this case, CEUS identified a largely treated tumor with some residual internal flow, but was unable to visualize any major hepatic vascularity supplying the tumor. In conclusion, CEUS appears to be a valuable tool for planning retreatment of residual HCC post-TACE.The Society of Radiologists in Ultrasound convened a panel of specialists in contrast-enhanced ultrasound (CEUS) to produce a white paper on noncardiac CEUS in North America. The panel met in Chicago, Illinois, on October 24 and 25, 2017. The recommendations are based on analysis of current literature and common practice strategies and are thought to represent a reasonable approach to introduce the advantages of this safe and noninvasive technique for the benefit of our patients. Characterization of liver nodules, and pediatric vascular and intravesicular applications comprise the approved indications for CEUS in the United States. They, along with the very successful off-label use of CEUS for the kidney, are included in this publication.Other off-label uses are presented with emphasis on their value and literature support in the online version.The coronavirus disease 2019 is caused by the severe acute respiratory syndrome coronavirus 2. The virus can be spread by close person-to-person contact primarily by respiratory droplets. Given the close proximity of the sonographer or sonologist with the patient during ultrasound examinations, special precautions should be taken to limit the exposure of radiology personnel to patients with coronavirus disease 2019 while still providing optimal patient care. Methods covered in this article include modified workflow, close scrutiny and prioritization of imaging orders, and design of targeted ultrasound protocols. These guidelines summarize the personal experience and insight of multiple colleagues who lead ultrasound sections or are experts in the field.
Surgical simulation is valuable in neurovascular surgery given the progressive rarity of these cases and their technical complexity, but its use has not been well described for pediatric vascular pathologies. We herein review the use of surgical simulation at our institution for complex pediatric aneurysmal malformations.

A retrospective review of patients treated for middle cerebral artery aneurysmal malformations with surgical simulation assistance (SuRgical Planner [SRP]; Surgical Theater, Mayfield Village, OH) during a 2-year period at Rady Children's Hospital of San Diego was performed.

In 5 pediatric patients with complex MCA aneurysmal malformations (mean age = 33.2 ± 49.9 months), preoperative 3-dimensional (3D) interactive modeling informed treatment planning and enhanced surgeon understanding of the vascular pathology. Availability of intraoperative simulation also aided real-time anatomical understanding during surgery. Specific benefits of simulation for these cases included characterization of involved perforating vessels, as well as an enhanced understanding of flow patterns within associated complex arteriovenous fistulas and feeding vessel/daughter branch anatomy. Despite the complexity of the lesions treated, use of simulation qualitatively enhanced surgeon confidence. There were no perioperative complications for patients treated with open surgery.

Surgical simulation may aid in the treatment of complex pediatric aneurysmal malformations.

Despite the significant role that stress plays in clinical care and education and the potential benefit of virtual reality (VR) as a simulation modality, there is a dearth of literature on stress and VR. The results of this scoping review have shown the positive effect that VR simulation can have on mitigating the negative aspects of stress during simulation and clinical training as well as improving provider performance and affect. Virtual reality technology, and immersive VR specifically, has the potential to powerfully transform how simulation education is being conducted. Because of this, the authors encourage researchers to put more focus into this topic and in determining how VR can be used to provide simulations with excellent training and a strong sense of presence for the purpose of addressing how stress can impact learners' clinical training and performance.
