Assessment and Biodistribution of a Dual Ultrasound Contrast and Photoacoustic Imaging Agent

This study by Yosra Toumia et al. advances the knowledge of the behavior of a hybrid system consisting of pristine graphene anchored polyvinyl alcohol microbubbles (G/PVA MB), and is a proof concept for their efficiency as contrast agents in photoacoustic as well as ultrasound imaging.

EKV: Maximum Frame Rate Imaging for Maximum Resolution

EKV, or ECG-gated Kilohertz Visualization, allows for increased temporal and spatial resolution imaging. By averaging multiple cardiac cycles, typical B-mode frame rates are increased from ~300 frames/sec to up to 10,000 frames/sec! This simple and quick acquisition mode generates presentation quality videos that accurately resolve small animal cardiac motion, with heart rates commonly between 300 and 600 bpm.

EKV helps with measuring a variety of normal and disease states including:

Myocardial wall motion
Abdominal aortic aneurysm models
Pulsed wave velocity measurements in atherosclerosis
Valvular dynamics
