This multicenter study aimed to determine the reproducibility of quantitative SPECT images reconstructed using a commercially available method ordered-subset conjugate-gradient minimization. Methods: A common cylindric phantom containing 100 kBq/mL concentration 99mTc-pertechnetate solution in volume 7 L was scanned under standard imaging conditions at 6 institutions local cli...

a 13 years old boy with severe abdominal pain and history of intermittent (ii bleeding since the aye of 3 months, is presented. different diagnostic procedures were unremarkable. a tc-99m pertechnetate abdominal study revealed abnormal radionuclide accumulation in small bowel region. duplication of small bowel was suspected which was confirmed by surgery and pathologic examination.
