To assess the ability of power Doppler ultrasonography (PDU) to detect acute pyelonephritis and to compare the findings from PDU with those from enhanced computed tomography (CT).
Eleven patients (mean age 18.5 years, range 5-37) admitted to hospital with a clinical diagnosis of pyelonephritis were assessed with PDU and enhanced CT. the latter providing the reference method.
The imaging studies showed normal findings in three patients; a single focus of pyelonephritis was detected by CT in six, whereas a matching defect was detected on PDU in five, with PDU failing to detect an infective focus in one. Multifocal diffuse pyelonephritis was diagnosed correctly by enhanced CT and PDU in two patients.
Power Doppler ultrasonography had an overall sensitivity of 88% and complete specificity in the evaluation of patients with acute pyelonephritis.
评估能量多普勒超声（PDU）检测急性肾盂肾炎的能力，并将PDU的检查结果与增强计算机断层扫描（CT）的结果进行比较。
对11例临床诊断为肾盂肾炎的住院患者（平均年龄18.5岁，范围5 - 37岁）进行了PDU和增强CT检查，后者作为参考方法。
影像学检查显示3例患者结果正常；CT检测到6例患者有单个肾盂肾炎病灶，而PDU检测到5例有相应缺损，1例PDU未检测到感染灶。2例患者经增强CT和PDU正确诊断为多灶性弥漫性肾盂肾炎。
在评估急性肾盂肾炎患者时，能量多普勒超声的总体敏感性为88%，特异性为100%。
