Abstract

We report on the use of Tc-99m hexamethylpropylene amineoxime (HMPAO) in watershed infarcts in five patients who had focal neurologic symptoms. Good correlation between Tc-99m HMPAO and CT was found in two patients. In three patients only Tc-99m HMPAO SPECT in a watershed distribution showed a perfusion abnormality that explained the clinical findings. Tc-99m HMPAO SPECT may be more sensitive than CT in the detection of infarctions in the watershed distribution.

摘要

我们报告了5例有局灶性神经症状的分水岭梗死患者使用锝-99m六甲基丙烯胺肟（HMPAO）的情况。在2例患者中发现锝-99m HMPAO与CT之间有良好的相关性。在3例患者中，仅分水岭分布区域的锝-99m HMPAO单光子发射计算机断层扫描（SPECT）显示灌注异常，这解释了临床发现。锝-99m HMPAO SPECT在检测分水岭分布区域的梗死方面可能比CT更敏感。
