(A*) TOP: Labeled as a "typical" lymphoscintigraphy finding in an article disputing the value of lymphoscintigraphy, the lateral view depicts the poor quality of injection and imaging technique . The injection site is represented by the solid arrow, the faint, barely visible SN by the open arrow. (B) BOTTOM: Right lateral view of typical/average result from optimized injection and imaging protocol showing injection sites (solid arrow) and bright sentinel node (open arrow) as well as lymphatic channel leading to sentinel node . In many cases, even much brighter nodes than depicted in B are found. *Reprinted from Am J Surg. 177, Burak WE Jr, Routine preoperative lymphoscintigraphy is not necessary prior to sentinel node biopsy for breast cancer, 445–449., 1999, with permission from Elsevier Ltd.; Excerpta Medica Inc . .
