Objective: To compare the diagnostic value of barium enema (BE), computed tomography (CT) and magnetic resonance imaging(MRI) in primary colorectal carcinoma.
Methods: A total of 64 patients with suspected colorectal carcinoma received BE (n=39), spiral CT (n=31) and MRI (n=42). The detective results were compared with the surgical results.
Results: Among 64 patients, 54 cases were pathologically proved as colorectal carcinoma. The diagnostic sensitivity of BE,CT and MRI was 96.9% ,96.2% and 97.1% ,and the overall accuracy was 92.3% 83.9 % and 90.5% respectively. The overall accuracy of CT and MRI for tumor T staging was 73.1% and 82.9% respectively.
Conclusion: BE can be considered as a primary approach for diagnosing colorectal carcinoma, CT and MRI be necessary diagnostic approaches. Combined BE with MRI is the best choice for diagnosing of colorectal carcinoma.
