ACUSON Juniper ultrasound system VB10 SW Release Virtual Touch Strain === Imaging (eSie Touch Elasticity Imaging)1 ealthineers ACUSON Juniper Quick Reference Card Using Strain imaging to qualitatively assess relative tissue stiffness Step 1 Elasticity • Position patient to obtain perpendicular plane to skin surface for optimal axial 12L3 Breast motion Tx Power 100% MI 0.94 TIS 0.2 • Position compatible transducer2 over area of interest and optimize B-mode image DTCE High Dyn R 68 dB THI 10.0 MHZ Select Elasticity tab on touch screen 1 dB • 12 fps HD QF 90 • Roll trackball to position region of interest (ROI) • Press Set key and roll trackball to resize ROI Note: The B-mode image and elastogram display in live, dual format (Fig. 1). The elasticity imaging bar (located above the grayscale bar) represents the range of gray or color shades available for depicting tissue stiffness from Fig. 1: Left: B-mode image with ROI. Right: B-mode image with corresponding SF (soft) to HD (hard). ROI displaying elastogram. 1 Note: This Quick Reference Card uses the term “Strain imaging” to refer to “eSie Touch elasticity imaging” displayed as “eSie Touch” under the “Elasticity” tab on the ultrasound system. 2 Strain imaging is compatible with 16L4, 13L4, 12L3, 11L4: Breast, Thyroid; 18H5: Thyroid. SIEMENS Healthineers Step 2 12L3 Breast MI 1.17 TIS 0.2 • Use minimal compression; avoid lateral or TIB 0.2 SC 2 rocking motion DTCE High Dyn R 68 dB THI 8.4 MHZ -2 dB Tip: Patient respirations or cardiac motion may 11 fps QF O be sufficient. • Adjust axial motion or cease lateral movement if gray overlay box appears on elastogram (Fig. 2) • Maintain QF > 50 Note: The system displays a real-time quality factor (QF) 4 cm score. A QF value > 60 (Fig. 1) indicates minimal global motion artifact. A QF value < 50 (Fig. 2) indicates a less than optimal result; perform another acquisition. Fr1166 Fig. 2: A gray overlay box on the elastogram indicates insufficient or excessive axial motion or lateral movement.

Tip: Shadow may be used with the strain ratio or EI/B ratio. • On a live or frozen image, press Caliper • Select Shadow • Measure the right or left image • Select Caliper to exit measurements Strain Ratio Compares the relative stiffness of tissue within two ROIs Strain Ratio (e.g., compares average strain of a lesion and average strain of the surrounding tissue). Strain ratio = 1: stiffness of tissue in both ROIs is equal. • On a frozen image, press Caliper Strain ratio > 1: Select Strain Ratio lesion is harder than surrounding tissue. • Place ROI 1 (ellipse) in surrounding tissue and press Set key Strain ratio < 1: • lesion is softer than surrounding tissue. • Place ROI 2 (ellipse) in lesion (same size and at same depth) Note: Results reflect placement of ROI 1 in and press Set key surrounding tissue; results will differ if ROI 1 Note: ROI size may be adjusted by rotating Select rotary control located on is placed in lesion. the control panel. Strain ratio and average strain (%) for both ROIs are displayed in the measured results. Note: Strain Ratio is not available when using EI Color. Distance Ratio or Area Ratio Elasticity imaging/B-mode (EI/B) ratio May be used as an indication of the likelihood of malignancy in breast lesions. When the ratio is > 1, the probability of malignancy is high.1 More % • On a frozen image, press Caliper % Select More Dist Ratio Area Ratio • Select Dist Ratio or Area Ratio 1 A • 0.31 cm2 B 0.11 cm2 • Measure lesion on elastogram and press Set key A/B 2.81 BIA 0.36 Measure lesion on B-mode image (A-B)/A 0.64 • • The EI/B ratio is represented by the A/B ratio in the measurement display area 1 Barr, R.
