If compared to two-dimensional echocardiography (2DE), myocardial contrast echocardiography (MCE) improves detection of coronary artery disease (CAD) during pharmacological stress, but data on MCE vs. 2DE during supine bicycle stress is limited. Alth

Chylopericardium is a rare disease that may result from a variety of causes, such as cardiac surgery, trauma, obstruction of the thoracic duct near its drainage into the subclavian vein, or have no identifiable underlying cause. The present report de

The purpose of this study was to develop and evaluate a new imaging modality (echoscintigraphy) to reduce color blooming and acoustic shadowing in contrast sonography. After injection of various amounts (700 to 40,000 bubbles/mL) of the echo contrast
