CT对超声和胆道X线造影未检出的胆石症的诊断价值(附29例分析)

Discussion of Diagnosis Gallstone by CT after Failue by Ultrasonic and X-ray Cholecystography

本文探讨用CT平扫及胆道造影CT捃描技术诊断了28例超声和胆道X线造影未能检出的胆石症。病例选择临床症状较典型,反复经超声扫描和胆道X线造影未能显示病变的病人。其中8例经CT平扫已明确诊断,另外21例平扫未检出,用胆道造影CT扫描,并变换体位,观察到胆囊内随体位变化而移动的结石影,确定了诊断。育8例经手术得以证实。作者认为,CT诊断胆石症由于费用较高,尚不宜作为首选方法,但当超声和X线胆道造影未能明确诊断时,仍不失为较理想的检测手段。

The article discussed the technique of CT scan and cholecystography to diagnose 29 cases negative gallstone on ultrasonic and x-ray cholecystography. The cases which the clinic symptom were typical and weren't defectes by ultrasonic scan and x- ray cholecystography were choose. Besides 8 cases of patients were diagnosed definitly on the no contrast, the other 6 cases of patients were observated shifting calculus in gallbladder with position change by CT scan cholecystography, yet, 8 cases were proved by the surgical operation. The author consider it costs too much that the gallstone diagnosed by CT. It couldn't be the first choice method,but it is still a ideal medium after the examination of ultrasonic and x - ray cholecystography was not successful.
