Abstract

Krypton-81m, an inert, radioactive gas with a physical half-life of 13 seconds was used to evaluate regional lung ventilation in 25 pediatric patients. The results suggest that Kr-81m has several advantages over previous methods employing xenon-133. These include: more favorable physical characteristics for imaging with present scintillation cameras; ease of performance of the examinations; improved resolution and multiple views with better detection and localization of abnormalities; and a much lower dose to the patient.

摘要

氪-81m是一种物理半衰期为13秒的惰性放射性气体，用于评估25例儿科患者的局部肺通气情况。结果表明，与先前使用氙-133的方法相比，氪-81m具有若干优势。这些优势包括：对于现有的闪烁相机成像而言，其物理特性更有利；检查操作简便；分辨率提高，可进行多视角观察，能更好地检测和定位异常；对患者的辐射剂量低得多。
