초록

One of common causes of cold defects on bone scintigraphy is an attenuation artifact. Cold defects can be produced by belt buckles, buttons, earring, necklaces, or other metal objects. Cold lesions in the abdomen are also produced by retained barium in the gastrointestinal tract after recent barium studies. We observed artifacts due to retained barium in the colon on bone scintigraphy, which simulated cold bone metastases in two patients with extraskeletal cancer.
