Value of 16-layer spiral CT in the diagnosis of large intestine carcinoma

Objective To explore the value of 16-layer spiral CT in the diagnosis of large intestine carcinoma.Methods Sixty eight patients with large intestine carcinoma received the 16-layer spiral CT scanning and imaging analysis.Also the location,shape,growth pattern,and pathological type of the carcinoma and Duke's staging were analyzed.Control study was made in the results between this method and electronic enteroscope and pathological examination.Results Among the 68 cases,60 ones were diagnosed by spiral CT.The CT scanning manifestation was filling defects and narrow of enteric cavity in different degrees.Enhanced CT showed middle degree and obvious enhancement.There was no significant difference in the accuracy rate of diagnosis for the pathological types of large intestine carcinoma between the CT and colonoscopic examinations(P 0.05).The accuracy rates of CT for the judgment of Duke's A,B,C1,C2,and D stages were 60.0%,72.7%,68.8%,57.1%,and 100%.Conclusion The 16-layer spiral CT can clearly show the shape and growth pattern of large intestine carcinoma and judge the pathological type and stage.It plays a great role in the diagnosis and treatment of large intestine carcinoma.
