This study was undertaken to determine the effect of chronicity of infection on the sensitivity of In-111-labeled leukocyte scanning. A total of 332 scans on 290 patients were reviewed retrospectively. The diagnosis of infection was based on culture results and other laboratory data, autopsy findings, radiographic studies, and clinical course. Duration of infection at the time of scanning was determined by the date of onset of fever and symptoms, elevation of white cell count, positive cultures, and abnormal findings on radiographic studies. Sensitivity of leukocyte scanning was 90% for 69 patients who had infections for 0-14 days and 86% for 86 who had infections for 15 days or longer. This difference is not statistically significant.
本研究旨在确定感染的慢性程度对铟-111标记白细胞扫描敏感性的影响。回顾性分析了290例患者的332次扫描结果。感染的诊断基于培养结果及其他实验室数据、尸检结果、影像学检查和临床病程。扫描时感染的持续时间根据发热和症状的起始日期、白细胞计数升高、培养阳性以及影像学检查的异常结果来确定。69例感染0至14天的患者白细胞扫描敏感性为90%，86例感染15天或更长时间的患者白细胞扫描敏感性为86%。这种差异无统计学意义。
