A Pitfall We Should Be Aware of on Bone Scintigraphy.

Nuclear medicine imaging frequently encounters injection artifacts. Although inadvertent intra-arterial injection is infrequent, it may pose diagnostic difficulties in pathological contexts. We present a case study of a woman with breast cancer and increased bone uptake in her right forearm and hand on bone scintigraphy. The pitfall was corrected by her clinical background and three-phase bone scintigraphy.
