ABSTRACT
Objective To study the CT signs of bronchotracheal transparent foreign body and its diagnostic value.Methods The X-ray and CT findings of bronchotracheal trasparent foreign body in 46 cases were analysed comparativly.Results Among 46 cases,9 cases of trachea foreign body,13 cases of right bronchial foreign body,7 cases of left bronchial foreign body,2 cases of both sides of bronchial foreign body were showed directly by CT,and 8 cases of right bronchia foreign body,6 cases of left bronchia foreign body,1 case of both sides of bronchia foreign body showed indirectly on CT,the sensitivity was 100 percent,while the foreign body and its anatomical location could not be showed on X-ray film,but the indirect signs just like pulmonary emphysema,obstructive pulmonitis and drowned lung etc,could be showed by X-ray films in 34 cases.In another 12 cases were negative,the sensitivity was 73.9 percent.Conclusion The transparent foreign body can not be showed but indrect signs by X-ray film;While CT scan can not only shows the anatomical location of foreign body,but also the shape and size of the foreign body,it offers more information than X-ray films and has important refering value to clinicians to take out the foreign body.
ABSTRACT
Objective To evaluate CT staging and resectability of esophageal carcinoma.Methods The esophageal barium examination,esophagoscopy and CT scan were performed in 42 cases with esophageal carcinoma.CT findings were put the stress on analyzed.Results CT clearly demonstrated the location, thickness, actual length and extent of esophageal carcinoma as well as its relation with surrounding structures in all 42 cases.According to staging standard of Moss and Reining there were four stages,Ⅰ stage 0 case,Ⅱ stage 33 cases,Ⅲ stage 6 cases,Ⅳ stage 3 cases.In all cases,operations were in 34 cases,detecting were in 3 cases,no-operations were in 5 cases.Conclusion CT imaging playes an important role in preoperative diagnosis,staging and the evaluation of resectability of esophageal carcinoma.
