Step 5 Tips and Techniques • Start the Timer at the conclusion • Practice quiet breathing with patient before the of the contrast agent injection Timer contrast run – sometimes a breath hold is necessary (Fig. 7) Fig. 7 • Small lesions are best visualized in long axis versus • Start the Clip capture at the a transverse plane appearance of the first bubble Clip • on the imaging screen (Fig. 8) Optimize your image before injection – changes in Fig. 8 depth, gain, etc., during the contrast run can have an • Continue pressing the Clip Capture adverse effect on calculation / quantification software key at the termination of each clip • (if necessary) for the duration of Patient history is very important. Cardiac issues may the contrast run delay contrast arrival in region of interest just as a mechanical heart valve can destroy bubbles as they pass through them • If no contrast is seen in the field of view, check the I.V. site to ensure the contrast has not gone interstitial (use a linear transducer to scan the injection site if necessary) Step 6 (optional controls) Burst • Engage a bubble destruction option if necessary during the Flash Sequence exam (Fig. 9a) • Engage the Peak Hold persistence Fig. 9a: Bubble destruction options option if necessary during the Burst and / or Flash exam (Fig. 9b) Sequence Tip: A Peak Hold persistence is an excellent tool for use in cases of Peak Hold low contrast agent concentration in the ROI Fig. 9b: Peak Hold persistence option siemens-healthineers.com/sequoia 3 For the proper use of the software or hardware, please always use At Siemens Healthineers, our purpose is to enable healthcare the Operator Manual or Instructions for Use (hereinafter collectively providers to increase value by empowering them on their journey “Operator Manual”) issued by Siemens Healthineers.
