Emission computed tomography (ECT) was used to examine 48 patients with suspected renal lesions. Sectional images of renal cysts diagnosed in 14 of them were characterized by well-defined outlines surrounded by uniformly declining radiopharmaceutical accumulations. Renal tumors were detected in 25 patients. ECT pattern of the tumor had obscure borders suggesting the tumor invasion into the renal tissue. Accumulation of the radiopharmaceutical round the tumor was less pronounced than in functioning renal tissue. According to ECT findings, 8 subjects were free of urological pathology. It is concluded that ECT is a promising diagnostic tool in urology as it permits sectional visualization of renal neoplasms structure, is highly sensitive, informative and noninvasive. It can identify mass lesions of the kidneys and warrants exhaustive information on functional performance of the renal parenchyma.
发射计算机断层扫描（ECT）用于检查48例疑似肾脏病变的患者。其中14例被诊断为肾囊肿的患者的断层图像特征为轮廓清晰，周围放射性药物积聚均匀减少。在25例患者中检测到肾肿瘤。肿瘤的ECT模式边界模糊，提示肿瘤侵犯肾组织。肿瘤周围放射性药物的积聚不如正常功能的肾组织明显。根据ECT检查结果，8名受试者无泌尿系统病变。结论是ECT是泌尿外科一种很有前景的诊断工具，因为它可以对肾肿瘤结构进行断层可视化，具有高度敏感性、信息丰富且无创。它可以识别肾脏的肿块病变，并能提供关于肾实质功能表现的详尽信息。
