Figure 2

Images from real-time perfusion echocardiography (upper panels) in apical 4-chamber view in a patient with a malignant tumor in the left atrium. Image at left demonstrates the flash impulse high mechanical index followed by post-flash image (middle) and replenishment by contrast (image at right) with region of interest (ROI) manually traced in the tumor. Lower panel shows the time-intensity curve obtained by quantification software with estimation of myocardial blood volume at peak intensity (A), blood flow velocity (β) and regional blood flow (A x β). Yellow curve was defined by measurements of intensity at each time interval while red curve corresponded to exponential fitted time-acoustic intensity.
