Hodgkin disease: gallium imaging
Initial gallium scan is necessary at time of initial staging to
see if the lymphoma is gallium-avid; if not, gallium imaging will
not be repeated.
Ga-67 imaging defferentiates active (residual or recurrent)
disease from bulky nodal fibrosis, particularly in the abdomen and
mediastinum after treatment.
