Abstract

Background: Dynamic renal scintigraphy remains the recognized method for evaluation of kidney function and perfusion. Although there is an extensive body of knowledge about the use of technetium-99m-mercaptoacetyltriglycine (99mTc-MAG3), much less has been written about renal technetium-99m-ethylenedicysteine (99mTc-EC) scintigraphy. The aim of this study was to determine the normal value of renal function parameters in 99mTc-EC dynamic renal scintigraphy: Tmax and T1/2. The effects of age, left or right side in the retroperitoneal space, and sex on those parameters were examined.

Material and methods: The research was conducted on 123 patients (F/M: 70/53; aged 2-71; averaging 14.8 years of age) with at least one normal kidney. A total of 194 healthy kidneys were examined, including pediatric kidneys.

Results: According to this study, the normal value of Tmax is 2.85 min (± 1.16) and T1/2 is 8.7 min (± 3.61). Values calculated for pediatric studies are Tmax is 2.81 (± 1.16) and T1/2 is 8.63 (± 3.71).

Conclusions: The normal value of secretory and excretory renal function parameters was calculated. Although the value is slightly lower for children, this is not statistically significant, as globally there are no differences between the kidney-location sides and sexes for any parameter.

99mTc-EC肾显像肾功能参数的正常范围。

背景:动态肾显像仍然是评估肾功能和灌注的公认方法。尽管关于锝-99m-巯基乙酰三甘氨酸(99mTc-MAG3)的使用有广泛的知识体系，但关于肾脏锝-99m-乙基半胱氨酸(99mTc-EC)显像的报道却少得多。本研究的目的是确定99mTc-EC动态肾显像中肾功能参数Tmax和T1/2的正常值。研究年龄、腹膜后间隙左侧或右侧以及性别对这些参数的影响。材料与方法:研究对象为123例患者(F/M: 70/53;年龄在2 - 71;平均年龄14.8岁)，至少有一个肾脏正常。总共检查了194个健康肾脏，包括儿童肾脏。结果:本研究Tmax正常值为2.85 min(±1.16)，T1/2正常值为8.7 min(±3.61)。小儿研究的计算值为Tmax为2.81(±1.16)，T1/2为8.63(±3.71)。结论:计算出分泌、排泄肾功能参数正常值。虽然儿童的数值略低，但这在统计学上并不显著，因为在全球范围内，肾脏位置两侧和性别之间的任何参数都没有差异。
