Contrast-enhanced dark lumen PET/CT and MR colonography in a rodent polyp model: initial results with histopathologic correlation

AJR Am J Roentgenol. 2005 Oct;185(4):1045-7. doi: 10.2214/AJR.04.1337.

Abstract

Objective: The objective of this study was to assess the feasibility of PET/CT for the detection of colorectal masses in a rodent polyp model in an intraindividual comparison with dark-lumen MR colonography.

Conclusion: Detection of small tumors with PET/CT and MR colonography is possible in a rodent model. The technique thus warrants further evaluation in animal studies as well as in patients with suspected colorectal disease.
