Abstract

Aims and objectives: 1) To study the role of CT Enterography and MR Enterography in diagnosing various small bowel diseases.2 )To compare the diagnostic significance of CT Enterography with MR Enterography 3)To evaluate the clinical significance of various imaging findings as detected on CT and MR enterography.

Summary: A prospective observational study done in 50 patients with clinical symptoms of small bowel diseases who underwent ileocolonoscopy were included in the study. CT and MR enterography was performed in all the patients and findings analyzed. Further they were followed up with HPE/Surgical findings. The sensitivity and specificity of CTE for diagnosing small bowel diseases was found to be 89.6% and 66.6% respectively. The sensitivity and specificity of MRE for diagnosing small bowel diseases was 88.8% and 78.2% respectively. The sensitivity and specificity of CTE for diagnosing crohn’s disease was 77.7% and 95.1% respectively. The sensitivity and specificity of MRE for diagnosing Crohn’s disease was 77.7% and 97.5% respectively.

Keywords: Small bowel imaging ,CT enterography, MR enterography.
