The authors performed abdominal scintigraphy using intravenously administered Tc-99m dextran in a patient with protein losing enteropathy. The study revealed abnormal leakage of the radiotracer in the left lumber area that moved over time in a pattern suggestive of small intestinal transit. Besides being a nonprotein and having long stay in intravascular compartment, the macromolecule may have many advantages over Tc-99m human serum albumin, the current radiotracer of choice for imaging intestinal protein loss.
作者对一名患有蛋白丢失性肠病的患者静脉注射锝-99m右旋糖酐后进行了腹部闪烁扫描。研究显示，放射性示踪剂在左腰部区域异常渗漏，且随时间移动，呈现出小肠转运的模式。除了是非蛋白质且在血管腔内停留时间长外，这种大分子相对于锝-99m人血清白蛋白（目前用于成像肠道蛋白丢失的放射性示踪剂）可能具有许多优势。
