Influence of bowel preparation before 18F-FDG PET/CT on physiologic 18F-FDG activity in the intestine


Soyka, J D; Strobel, K; Veit-Haibach, P; Schaefer, N G; Schmid, D T; Tschopp, A; Hany, T F (2010). Influence of bowel preparation before 18F-FDG PET/CT on physiologic 18F-FDG activity in the intestine. Journal of Nuclear Medicine, 51(4):507-510.

Abstract

Our objective was to investigate the use of bowel preparation before (18)F-FDG PET/CT to reduce intestinal (18)F-FDG uptake.

METHODS: Sixty-five patients with abdominal neoplasias were assigned either to a bowel-preparation group (n = 26) or to a native group (n = 39). (18)F-FDG activity was measured in the small intestine and the colon.

RESULTS: In the 26 patients with bowel preparation, average maximal standardized uptake value (SUVmax) was 3.5 in the small intestine and 4.4 in the colon. In the 39 patients without bowel preparation, average SUVmax was 2.6 in the small intestine and 2.7 in the colon. (18)F-FDG activity impaired diagnosis in 6 patients (23%) in the bowel-preparation group and 11 patients (28%) in the native group (P = 0.5). SUVmax in the colon was significantly higher in the bowel-preparation group (P = 0.002), but SUVmax in the small intestine did not significantly differ between the 2 groups (P = 0.088).

CONCLUSION: Bowel preparation increases (18)F-FDG activity in the large intestine and is therefore not useful before PET/CT..

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
