Contrast-Enhanced Ultrasound for Image-Guided Procedures.

Contrast-enhanced ultrasound (CEUS) uses intravenously injected gas microbubbles as a pure blood pool contrast agent to demonstrate blood flow and tissue perfusion at a much higher sensitivity than color Doppler and power Doppler ultrasound. CEUS has gained traction in abdominal diagnostic imaging for improved lesion detection and characterization and a complementary problem-solving tool to CT and MRI. In addition to its diagnostic applications, CEUS has also proven useful for pre-procedure planning, procedure guidance, and post-procedure evaluation.

Peripheral nodular enhancement in adrenal and renal hematomas: A report of 3 cases.

There are a wide range of benign and malignant pathologies that the radiologist may encounter in the adrenal glands and kidneys, often incidentally when imaging is performed for other indications. Many imaging modalities including CT, MR, and US are often used in an attempt to characterize these lesions. A definitive radiological diagnosis, however, is not always possible.

Identification of aspirated radiolucent foreign bodies in the pediatric airway using digital tomosynthesis: a multireader phantom study.

Foreign body aspiration is difficult to diagnose because many aspirated foreign bodies are low density or radiolucent. Digital radiographs (DR) are poor at detecting radiolucent foreign bodies. Digital tomosynthesis (DTS) has been shown to be ideally suited for applications where DR is insensitive and the increased dose from computed tomography (CT) is not justified.

Effect of Simulation Training on Cognitive Performance Using Transesophageal Echocardiography.

Simulation is used in anesthesia training to reinforce didactic learning. The authors hypothesized that knowledge acquisition in the use of transesophageal echocardiography (TEE) could be accomplished better through the use of a simulator than with online or web-based learning. A total of 71 student registered nurse anesthetists were randomly assigned to either web-based or simulator-based TEE training.
