Abstract

Purpose

Evaluation of diagnostic accuracy of abdominal CT depending on the type of enteric contrast agent.

Methods and materials

Multislice CTs of 2,008 patients with different types of oral preparation (positive with barium, n = 576; neutral with water, n = 716; and no enteric contrast, n = 716) were retrospectively evaluated by two radiologists including delineation of intestinal segments and influence on diagnosis and diagnostic reliability exerted by the enteric contrast, using a three-point scale. Furthermore, diagnostic reliability of the delineation of selected enteric pathologies was noted. CT data were assigned into groups: oncology, inflammation, vascular, pathology, trauma and gastrointestinal pathology.

Results

Delineation of the bowel was clearly practicable across all segments irrespective of the type of enteric contrast, though a slight impairment was observed without enteric contrast. Although delineation of intestinal pathologies was mostly classified “clearly delimitable” more difficulties occurred without oral contrast (neutral/positive/no contrast, 0.8 %/3.8 %/6.5 %). Compared to examinations without enteric contrast, there was a significant improvement in diagnosis that was even increased regarding the reader’s diagnostic reliability. Positive opacification impaired detection of mucosal enhancement or intestinal bleeding.

Conclusion

Water can replace positive enteric contrast agents in abdominal CTs. However, selected clinical questions require individual enteric contrast preparations. Pathology detection is noticeably impaired without any enteric contrast.

Key Points

• Neutral oral contrast ensures an equivalent delineation of the bowel.
• Neutral contrast ensures a similar detection rate for intestinal pathologies.
• Positive enteric contrast should be used in selected questions (suspected fistulas, abscesses).
• Detection of pathologies and bowel delineation proved more difficult without oral contrast.
• Diagnosis and the reporting physician’s diagnostic reliability are impaired without enteric contrast.
