Artefacts or not completely visualised renal contours can lead to the erroneous diagnosis "renal tumour". This false diagnosis is mostly avoidable by means of accurate examination technique. Further radiological examination will be required only in exceptional cases. Incompletely visualisable parenchymal ridges with socalled incomplete multiple kidneys frequently create the impression of an intrarenal tumour and indicate the need for further clarification. There is a relatively high degree of uncertainty in intrarenal space-occupying processes below 2.5 cm diameter, as far as structural analysis is concerned. In such cases, provided a sufficiently strong clinical and roentgenological suspicion is sustained, angiography and, if necessary, exposure, should be recommended on a rather liberal basis.
伪影或未完全显示的肾轮廓可导致错误诊断为“肾肿瘤”。通过准确的检查技术，这种错误诊断大多是可以避免的。仅在特殊情况下才需要进一步的放射学检查。所谓的不完全重复肾中不可完全显示的实质嵴常常会造成肾内肿瘤的假象，并表明需要进一步明确。就结构分析而言，直径小于2.5 cm的肾内占位性病变存在相对较高程度的不确定性。在这种情况下，如果有足够强烈的临床和放射学怀疑，应较为宽松地建议进行血管造影，必要时进行暴露检查。
