A method of high frequency image filtration improving the quality of imaging, and more precise renometry with measurement of the total count and the level of RP kidney accumulation were used for raising the informative value of the results of renal scintigraphy with 99m Tc-DMSA. 54 patients with unilateral pyelonephritis, 46--with bilateral pyelonephritis, 15--with nephroptosis, and 10 healthy persons were examined. Informative values were calculated on the basis of the results of these investigations. The sensitivity of routine renometry was 0.88, its specificity--0.27 and precision--0.78; the same indices for routine static scintigraphy were 0.88; 0.4 and 0.84; for modified renal investigations--0.98; 0.77 and 0.96, respectively. The results of the investigations have shown that the use of scintigraphy with improved quality of kidney images in parallel with modified renometry raises the informative value of renal studies with 99m Tc-DMSA and precision of diagnosis of renal parenchymal lesions.
一种提高成像质量的高频图像过滤方法，以及通过测量RP肾蓄积的总数和水平进行更精确的肾测定，被用于提高99m Tc - DMSA肾闪烁显像结果的信息量。对54例单侧肾盂肾炎患者、46例双侧肾盂肾炎患者、15例肾下垂患者和10名健康人进行了检查。根据这些调查结果计算信息量。常规肾测定的敏感性为0.88，特异性为0.27，精确度为0.78；常规静态闪烁显像的相同指标分别为0.88、0.4和0.84；改良肾检查的相应指标分别为0.98、0.77和0.96。研究结果表明，使用具有改善肾脏图像质量的闪烁显像并结合改良肾测定，可提高99m Tc - DMSA肾研究的信息量以及肾实质病变诊断的精确度。
