What details can chest MRI show if you're looking for lymphoma?

Lymphoma Staging. A diagnosis of lymphoma is usually made by obtaining a sample of lymph nodes that is easily accessible by a surgeon. If there is not easilly accessible lymph node to biopsy because of their deeper location, needle aspiration biopsy may be done. Cat (computed axial tomography) scans with or without pet (positron emission tomography) scans rather than MRI are generally used in finding these nodes.
