Lymph Node Measurements, CT
 |
First, identify the longest diameter of a lymph node or nodal mass (17.6mm in this example) and then measure the longest perpendicular diameter to that as the short axis (10.6mm in this example). 10.6mm in the short axis defines this lymph node as being pathologic but not measurable. As such it shall be recorded as a non-target lesion. |
