Contrast Agent Uses Heart’s Electricity to Activate Itself
June 24, 2019 — Medgadget Imaging the heart for signs of disease is still quite rudimentary. While CT, ultrasound, and PET (positron-emission tomography) scanners generate impressive looking graphics, they’re a long way from giving doctors a true representation of the anatomy and function of the heart and nearby vasculature. Contrast agents are widely used to […]

Can CEUS Increase or Predict the Success Rate of Testicular Sperm Aspiration in Patients With Azoospermia?
May, 2019 – American Journal of Roentgenology ABSTRACT : OBJECTIVE. The objective of our study was to determine whether contrast-enhanced ultrasound (CEUS) perfusion measurements obtained before testicular sperm aspiration (TESA) can improve or predict sperm retrieval (SR) outcomes of TESA in patients with azoospermia. SUBJECTS AND METHODS. Between May 2017 and January 2018, 70 patients […]
Safety profile of ultrasound enhancing agents in echocardiography.
Apr 30, 2019 — Echocardiography Abstract INTRODUCTION: Ultrasound enhancing agents (UEAs) are often utilized to enhance ultrasound image quality; however, concerns about adverse reactions have limited their use. Moreover, these agents had been either contraindicated or are labeled with a warning in patients with intra-cardiac shunts because of a theoretic risk of systemic microvascular obstruction. […]
3D Super-Resolution US Imaging of Rabbit Lymph Node Vasculature in Vivo by Using Microbubbles
April, 2019 – Radiology Background: Variations in lymph node (LN) microcirculation can be indicative of metastasis. The identification and quantification of metastatic LNs remains essential for prognosis and treatment planning, but a reliable noninvasive imaging technique is lacking. Three-dimensional super-resolution (SR) US has shown potential to noninvasively visualize microvascular networks in vivo. Purpose: To study […]
