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。
This article discusses the CT scan and cholangiography CT scan technique diagnosed 28 cases of ultrasound and cholangiography failed to detect cholelithiasis. Case selection of clinical symptoms than typical, repeated ultrasound scan and biliary X-ray angiography failed to show the patient’s disease. Among them, 8 cases had been diagnosed by CT plain scan. In addition, 21 cases were not detected by plain scan. CT scan with cholangiography was performed. The position of the gallbladder was changed and the movement of the gallbladder with the change of position was observed. Education 8 cases were confirmed by surgery. The author believes that CT diagnosis of cholelithiasis due to higher costs, not as the preferred method, but when the ultrasound and X-ray cholangiography failed to make a clear diagnosis, is still an ideal means of detection.
