The clinical utility of radionuclide emission tomography of the kidney in comparison with conventional gamma-camera imaging has been assessed from scans of 60 patients suspected of having space-occupying lesions of the kidney. Nineteen patients had renal tumour, 17 had cysts and seven had renal pseudotumours; the remainder had no lesion. Objective trials using four observers showed only a slight, statistically insignificant advantage from the addition of tomographic sections to conventional images. However, in several individual cases tomography had aided diagnosis, particularly in obese patients, when an alternative non-invasive investigation (ultrasonography) was inconclusive. In seven patients a positive diagnosis of renal pseudotumour was made possible by tomography; definite identification of ectopic functioning cortical tissue at the location of a mass suspected after urography was considered to be a distinct diagnostic advantage gained from emission tomography of the kidney.
通过对60名疑似患有肾脏占位性病变患者的扫描，评估了肾脏放射性核素发射断层扫描与传统γ相机成像相比的临床效用。19名患者患有肾肿瘤，17名患有囊肿，7名患有肾假肿瘤；其余患者无病变。由四名观察者进行的客观试验表明，在传统图像上增加断层扫描切片仅具有轻微的、无统计学意义的优势。然而，在一些个别病例中，断层扫描有助于诊断，特别是在肥胖患者中，当另一种非侵入性检查（超声检查）结果不明确时。断层扫描使7名患者的肾假肿瘤得到了阳性诊断；在静脉肾盂造影后怀疑有肿块的部位明确识别出异位功能性皮质组织，被认为是肾脏发射断层扫描获得的一项明显的诊断优势。
