Although CT scanning is the examination of choice in the assessment of mediastinal masses, at best, the findings only suggest the diagnosis of NHL. A tissue diagnosis is required. CT scanning can be invasive, and young patients may require sedation or a general anesthetic. In addition, CT scanning is expensive and exposes the patient to radiation. Moreover, patients may be allergic to iodinated contrast medium, which must be used with caution in persons with renal failure.
