Using computed tomography, the renal parenchymal volume and tissue-plasma ratio of contrast enhancement, with a bolus injection, were measured, and the latter measurement is believed to indicate regional renal function per unit of parenchymal volume. 67 studies were carried out on 50 patients, 17 of whom were examined pre- and postoperatively. Of these 50 patients, 27 had hydronephrosis, 6 had renovascular disease, 4 had pyelonephritis and the remaining 13 were control patients. The product of tissue-plasma ratio of contrast enhancement and the calculated renal parenchymal volume were found to be in good correlation with the individual renal function measured with 99mTc-dimercaptosuccinic acid and 131I-hippuran. Since this method is reproducible, the kidney being examined may be seen in more detail.
通过计算机断层扫描，在静脉团注造影剂的情况下，测量了肾实质体积和造影剂增强的组织-血浆比，后者的测量被认为可指示每单位实质体积的局部肾功能。对50例患者进行了67项研究，其中17例患者在术前和术后均接受了检查。在这50例患者中，27例患有肾积水，6例患有肾血管疾病，4例患有肾盂肾炎，其余13例为对照患者。发现造影剂增强的组织-血浆比与计算出的肾实质体积的乘积与用99mTc-二巯基丁二酸和131I-马尿酸测量的个体肾功能具有良好的相关性。由于该方法具有可重复性，因此可以更详细地观察被检查的肾脏。
