Imaging studies are important for accurate staging of Hodgkin lymphoma. These studies include plain x-rays, computed tomography (CT) scans, and positron emission tomography (PET) scans. In addition, imaging studies can help to define disease bulk, which has prognostic implications. The definition of bulky disease varies, but in general is defined as any nodal mass greater than 10 cm (>5 cm in some studies) and a mediastinal mass greater than one third the thoracic diameter as measured at T5/6.
