BACKGROUND: Transesophageal echocardiography (TEE) is a valuable monitor for patients undergoing cardiac and noncardiac surgery as it allows for evaluation of cardiovascular compromise in the perioperative period. It is challenging for anesthesiology residents and medical students to learn to use and interpret TEE in the clinical environment. A critical component of learning to use and interpret TEE is a strong grasp of normal cardiovascular ultrasound anatomy. METHODS: Fifteen fourth-year medical students and 15 post-graduate year (PGY) 1 and 2 anesthesiology residents without prior training in cardiac anesthesia or TEE viewed normal cardiovascular anatomy TEE video clips; participants were randomized to learning cardiac anatomy in generative retrieval (GR) and standard practice (SP) groups...

Accurate and robust non-rigid registration of pre-procedure magnetic resonance (MR) imaging to intra-procedure trans-rectal ultrasound (TRUS) is critical for image-guided biopsies of prostate cancer. Prostate cancer is one of the most prevalent forms of cancer and the second leading cause of cancer-related death in men in the United States. TRUS-guided biopsy is the current clinical standard for prostate cancer diagnosis and assessment. State-of-the-art, clinical MR-TRUS image fusion relies upon semi-automated segmentations of the prostate in both the MR and the TRUS images to perform non-rigid surface-based registration of the gland...

BACKGROUND: Pharmacologic prophylaxis for venous thromboembolism (VTE) is a widely accepted practice in adult trauma patients to prevent associated morbidity and mortality. However, VTE prophylaxis has not been standardized in injured pediatric patients. Our institution identified factors potentially associated with a high risk of VTE in critically injured children that led to prospective implementation of VTE prophylaxis guidelines. We hypothesize that the guidelines are accurate in predicting children at risk for VTE...

In this study, synergistic degradation of antibiotic norfloxacin (NOR) was obtained in a novel sonochemical ultrasound/zero-valent iron/tetraphosphate system (US/ZVI/TPP). Compared to three common organic ligands (EDTA, EDDS, and DTPA), TPP could perform more excellently in activation of O2 to produce reactive oxidative species (ROS) and lead to efficient Fenton-like oxidative degradation of NOR in the sonochemical in situ chemical oxidation (ISCO) system. An optimized initial condition was obtained as 10mg/L NOR, 0...

Microbubbles (MBs) serve as a critical catalyst to amplify local cavitation in CNS capillary lumen to facilitate focused ultrasound (FUS) to transiently open the blood-brain barrier (BBB). However, limited understanding is available regarding the effect of different microbubbles to induce BBB opening. The aim of this study is to characterize different MBs on their effect in FUS-induced BBB opening. Three MBs, SonoVue, Definity, and USphere, were tested, with 0.4-MHz FUS exposure at 0.62-1.38 of mechanical index (MI) on rats...

INTRODUCTION: There is variable international practice regarding the technique used for image-guided enema reduction in paediatric intussusception. A recent meta-analysis found pneumatic reduction to be more effective than hydrostatic techniques. Clinical practice variation may impact on perforation rates, ionizing radiation exposure and requirement for surgery. The aim of this study was to review the literature regarding the efficacy and safety of fluoroscopically guided pneumatic reduction (FGPR) compared to ultrasound (US) guided intussusception reduction (USGIR) techniques for paediatric intussusception treatment...

Neonates presenting with neurologic symptoms require rapid, noninvasive imaging with high spatial resolution and tissue contrast. Magnetic resonance imaging (MRI) is currently the most sensitive and specific imaging modality for evaluation of neurological pathology. This modality does come with several challenges in the neonatal population, namely, the need to transport a possibly critically sick neonate to the MRI suite and the necessity of the neonate to remain still for a significant length of time, occasionally requiring sedation...

Importance: Asymptomatic microscopic hematuria (AMH) is highly prevalent and may signal occult genitourinary (GU) malignant abnormality. Common diagnostic approaches differ in their costs and effectiveness in detecting cancer. Given the low prevalence of GU malignant abnormality among patients with AMH, it is important to quantify the cost implications of detecting cancer for each approach. Objective: To estimate the effectiveness, costs, and incremental cost per cancer detected (ICCD) for 4 common diagnostic approaches evaluating AMH...

Besides other innovative stereotactic procedures (radiofrequency thermocoagulation, focused ultrasound, gamma knife) laser interstitial thermotherapy (LiTT) provides minimally invasive destruction of pathological soft tissues which could be especially relevant for epilepsy surgeries involving adult and pediatric patients. Unlike standard resections, no craniotomy is required; just a tiny borehole trepanation is sufficient. Damage to cortical areas when accessing deep lesions can be minimized or completely avoided, and treating epileptogenic foci near eloquent or even vital brain areas becomes possible...

PURPOSE: Critical access hospitals face difficulty providing all services locally and may need to refer patients off-site for additional care. Providing on-site minimally invasive biopsies, may obviate visits to tertiary or quaternary care centers. This study aims to assess feasibility and outcomes of an ultrasound-guided thyroid biopsy program in a critical access hospital. METHODS: In this HIPAA compliant, IRB approved study, the Interventional Radiology (IR) database of a 19-bed, island, rural, critical access hospital without onsite pathology services affiliated with our quaternary care institution was retrospectively reviewed to identify all thyroid biopsies that were performed on site since inception of the service in April 2014 through August 2016...

Clinical data sharing between healthcare institutions, and between practitioners is often hindered by privacy protection requirements. This problem is critical in collaborative scenarios where data sharing is fundamental for establishing a workflow among parties. The anonymization of patient information burned in DICOM images requires elaborate processes somewhat more complex than simple de-identification of textual information. Usually, before sharing, there is a need for manual removal of specific areas containing sensitive information in the images...

Early identification of elevated intracranial pressure (ICP) is critical to ensuring timely and appropriate management to improve patient outcome. Measurement of the optic nerve sheath diameter by ultrasound is a well studied modality for noninvasive assessment of ICP. Recent studies have shown it to correlate with invasively measured ICP. We utilized this technique in our ICU and found it to be of great help in guiding patient management and predicting the prognosis. A case series of four patients is reported illustrating its utility in ICU patients...

The purpose of this review is to showcase the added value of scrotal magnetic resonance imaging (MRI) in the workup of neoplastic and non-neoplastic entities. While ultrasound (US) remains the first-line imaging modality for evaluating scrotal pathology, MRI may add valuable information, particularly when US findings are equivocal. The inherent soft tissue resolution characteristics of MRI, as well as the ability to detect subtle enhancement and provide wider field-of-view imaging, can prove useful in evaluating inconclusive US findings...
