RT Journal Article SR Electronic T1 Cholescintigraphy for Differentiation of True Duodenal Obstruction from Pseudo Obstruction JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 344 OP 345 DO 10.2967/jnmt.120.246132 VO 48 IS 4 A1 Rodrigue, Paul A1 Nepal, Pankaj A1 Assaker, Richard YR 2020 UL http://tech.snmjournals.org/content/48/4/344.abstract AB Small-bowel obstruction is a fairly common cause of abdominal pain. Differentiating between true duodenal obstruction and pseudo obstruction is important given differing treatment strategies. Here, we present augmentation of a hepatobiliary scan with a small amount of oral liquids and delayed imaging to differentiate between these two entities.
