FIGURE 1. A 28-y-old female was referred for primary diagnosis of a NET because of elevated tumor markers in serum. PET (A) clearly depicted an abnormal focus in upper abdomen (arrow). This lesion could be delineated in the pancreas after image fusion with CT (B). There was also increased contrast medium enhancement in the margin when using helical CT (C). SPECT with 99mTc-HYNIC-TOC was also positive for this tumor in upper abdomen (D). This positive finding was confirmed by histopathology revealing a NET with 1 cm in diameter.
