Combined transmission-emission imaging in lymphoscintigraphy

A modification of standard lymphoscintigraphic imaging is described that incorporates the use of a two-headed camera with flood source to provide combined whole-body transmission-emission images of lymphatic drainage in a patient with malignant melanoma. The most common imaging technique for lymphoscintigraphy uses single-head gamma cameras with or without skin markers. The authors performed both techniques on their patient, and believe that the modification may provide a clearer image for lymphoscintigraphic interpretation.
