For radial scanning, one should enter the stomach, inflate the balloon, and pull back the scope until the GE junction. The aorta with be visualized as a large round echo‐poor structure. The aorta should be rotated to the 5 o’clock position, and the spine will be at 7 o’clock with the azygos vein in the middle. Then the balloon should be deflated and a slow pull‐back is performed observing all the mediastinal areas. It is important to note that, for a complete lung cancer staging with both radial and linear, the celiac axis, the left adrenal, and the left lobe of the liver should be surveyed. This is easily accomplished with a slight tip down on the echoendoscope and and then pushing it into the stomach; the celiac take‐off can be seen and the left adrenal can be seen at the 6 to 4 o’clock position with its usual “seagull” appearance. For the liver, one goes to the gastric antrum, aspirates all the air, inflating the balloon, and then tip up with a slow pull‐back.
