Steps

1
Set up electromagnetic navigational aspiration system

Prepare and configure the electromagnetic navigation platform for transthoracic needle guidance. Calibrate imaging and navigation coordinates to ensure accurate real-time tracking of needle position relative to lung nodule anatomy.

2
Perform guided tissue sampling procedure

Under electromagnetic navigation, advance the transthoracic needle toward the target lung nodule and obtain tissue samples for pathologic assessment. Monitor needle trajectory and positioning throughout aspiration.

3
Compare sampling outcomes with alternative technique

Evaluate tissue yield and diagnostic quality from E-TTNA relative to EBUS-TBNA results to assess relative diagnostic utility of each navigational approach.
