Renal scintiscanning is a simple investigation that does not require special preparation and is well tolerated by patients. Radiopharmaceuticals used in linear scanning are accumulated in the renal cortex. This accumulation is diminished: (a) when the cortex is destroyed, e.g. by pyelonephritis, injury, etc.; and (b) when the amount available to the cortex is reduced, e.g. by ischaemia. The scintigram depicts the kidneys unimpeded by bowel contents, gives a qualitative assessment of renal function and shows the distribution of zones of normal function. Recent technical improvements show great promise in deriving a quantitative measure of renal function in some circumstances. The location of normally functioning cortex is often important in the management of renal diseases and the value of scintiscanning is then considerable. It is occasionally useful in planning surgery. The anatomy of the renal collecting system can be shown only by urography. High dose techniques achieve this even in the face of renal failure, and scintiscanning has few indications in investigating lesions that distort the renal anatomy, e.g. tumours and cysts. Renal scintiscanning is a very valuable additional method to urography, arteriography and renography in investigation of renal disorders.
肾闪烁扫描是一项简单的检查，无需特殊准备，患者耐受性良好。用于线性扫描的放射性药物会在肾皮质中积聚。这种积聚减少的情况如下：(a) 当皮质受到破坏时，例如因肾盂肾炎、损伤等；(b) 当皮质可利用的量减少时，例如因缺血。闪烁图描绘出未受肠内容物干扰的肾脏，对肾功能进行定性评估，并显示正常功能区域的分布。最近的技术改进在某些情况下有望得出肾功能的定量指标。正常功能皮质的位置在肾脏疾病的管理中通常很重要，此时闪烁扫描的价值相当大。它偶尔在手术规划中有用。肾集合系统的解剖结构只能通过尿路造影显示。即使面对肾衰竭，高剂量技术也能做到这一点，而在研究扭曲肾脏解剖结构的病变（如肿瘤和囊肿）时，闪烁扫描几乎没有适应证。肾闪烁扫描在肾脏疾病的检查中是尿路造影、动脉造影和肾造影之外非常有价值的辅助方法。
