Answer

Answer

Noninvasive preoperative evaluation of the mediastinum with CT or MRI is limited by substantial false-positive and false-negative results (30-40%, depending on the criteria used to define enlarged lymph nodes and the patient population). Positron emission tomography (PET) scanning and, possibly, surgical assessment of the mediastinum with lymph node sampling should be strongly considered before curative surgery is attempted.
