A/B Ratio
• Press “measure”.
• Select “A/B Ratio” measurement and type “Area”.
• Draw the first measurement at the elastography image (right) and the second at the reference B-mode image (left). TIP: The two drawing areas should be placed at the borders of the lesion (B-Mode) and at the color pattern borders of the elastogram (Elastography image).
E-Index
• Press “measure”.
• Select “Elasto” measurement.
• Draw the circle at the lesion of interest either on the elastogram or the B-Mode image. This measurement gives an absolute value between 0 (softest) and 6 (hardest). TIP: The circle should be placed at the borders of the lesion (B-Mode) or at the color pattern borders of the elastogram (Elastography image).
E-Ratio
• Press “measure”.
• Select “E-Ratio” measurement and type “Circle” or “Area”.
• Draw the first measurement at the reference tissue and the second at the lesion of interest. This measurement results in the calculation of the ratio of the E-Indexes of the two areas (reference and lesion). TIP: These two areas should be approximately at the same depth (side-by-side position) and size. Note: The value represents how many times stiffer the lesion is comparing to the reference tissue. If E-Ratio is less than 1, the lesion is softer than the reference tissue.
