Figure 4

Comparison of “passive” versus “active” visualization of needles during CMR guided pericardial access. The “passive” titanium needle (panel A, black artifact indicated with white arrows) is compared with an “active” antenna needle (panel B, green colorized signal indicated with white arrow). The active needle is more conspicuous. This demonstration uses a lateral access approach and no pericardial effusion.
