摘要
目的探讨螺旋CT低剂量扫描在诊断泌尿系结石中应用价值。方法对40例临床拟诊泌尿系结石的患者,行螺旋CT常规剂量和低剂量扫描及后处理技术检查。分析其敏感性和准确性。结果所有低剂量扫描及后处理图像均获得成功,低剂量扫描检查结石的敏感性为100%,准确性为98%。结论低剂量螺旋CT平扫是一种敏感、安全的输尿管结石的检查方法,它诊断输尿管结石能够获得高准确率,并且明显降低对病人的放射剂量,延长了球管的使用寿命。
Objective To evaluate the low-dose multislice CT（MSCT） in investigating urinary calculi. Methods 40 patients with suspected ureterolithiesis were collected. Followed by standard-dose helical CT scans and low--dose scans, the sensitivity and accuracy of standard-dose and low-dose MSCT were calculated respectively. Results With the low-dose scan, The sensitivity and accuracy rates of the detection of nephrolithiesis and ureterolithiesis on the low-dose scan were 100% and 98% respectively. Conclusion Low-dose MSCT is sensitive and safe in investigating ureterolithiasis. High accuracy for the detection of ureterelithiasis is obtained and the radiation dose is significantly decreased hy using low-dose MSCT performed.
