Answer

Answer

CT shows the anatomic details of the lesion well. CT may have lower sensitivity than MRI in detecting mediastinal invasion. Because CT staging involves criteria based on the size of the lymph nodes, CT has an inherent limitation. Disease may be overstaged if enlarged benign lymph nodes are measured, or disease may be understaged if the microscopically involved normal-sized nodes are classified as being benign.
