Objective To evaluate the effect of CT and US on diagnosing cardia carcinoma,and to analyse the anatomic basis. Method CT and US were performed in 220 normal subjects and 67 patients with cardia carcinoma,and their manifestations were compared. Results Three types of CT manifestation of cardia were mostly seen in the normal subjects:cone-shaped,pipe-shaped and sickle-shaped. While in the group of tumor,mass,hytrophy wall and outward intrusion were seen. Preoperative diagnostic accuracy of CT is 97%,that of US is 98.5%. Conclusion CT and US play a valuable role in the detection of tumors,upon which the possibility of cardiectomy is determined. |
