RT Journal Article SR Electronic T1 Gastrointestinal Motility, Part 2: Small-Bowel and Colon Transit JF Journal of Nuclear Medicine JO J Nucl Med FD Society of Nuclear Medicine SP 1395 OP 1400 DO 10.2967/jnumed.113.134551 VO 56 IS 9 A1 Alan H. Maurer YR 2015 UL http://jnm.snmjournals.org/content/56/9/1395.abstract AB Because of the difficulty often encountered in deciding whether a patient’s symptoms originate in the upper or lower gastrointestinal tract, gastrointestinal transit scintigraphy is a uniquely suited noninvasive, quantitative, and physiologic method of determining whether there is a motility disorder affecting the stomach, small bowel, or colon. Small-bowel and colon transit studies can be performed alone or together with gastric emptying studies after oral administration of an appropriately radiolabeled meal. It is hoped that newly published standards for performing these studies and the anticipated arrival of new Current Procedural Terminology codes in the United States for small-bowel and colon transit studies will increase their availability and use.
