Abstract:
OBJECTIVETo compare the diagnostic value of barium enema (BE), computed tomography (CT) and magnetic resonance imaging(MRI) in primary colorectal carcinoma.
METHODSA 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.
RESULTSAmong 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.
CONCLUSIONBE 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.
