英文摘要: Background(#br)Echocardiography with an ultrasound-enhancing contrast agent (CON) is a powerful tool for identifying the endocardial border. However, the precise relationship of measurements obtained from CON to the reference values of two-dimensional unenhanced echocardiography (BASL) remains undefined, especially regarding wall thickness. The aim of this study was to systematically determine the differences between unenhanced and enhanced images for a broad range of left ventricular (LV) measurements and to define reference values for the relationship between the two methods.(#br)Methods(#br)We examined the echocardiograms of 624 consecutive patients in whom CON was performed for clinical indications. We excluded 192 patients in whom studies were technically difficult for measurement by...
