某男性患者，48岁，右下腹痛伴高热4天，4天后始出现右上腹胀痛。查体：T39.6℃，右上腹触痛伴肌紧张，右下腹压痛及反跳痛。WBC15.6×10/L，N83.5%。X线透视：右膈肌抬高。Tc-HMPAO-WBC显像示右下腹放射性局灶性异常浓聚，肝内可见多发局灶性放射性分布异常浓聚影。临床选用Tc-HMPAO-WBC助诊。

以下有关Tc-HMPAO-WBC炎症显像的叙述正确的是

A:肝、脾及骨髓部位放射性浓聚 B:与In-Oxine-WBC比较，Tc-HMPAO-WBC炎症显像最大的不足在于肠腔内可有非特异性浓聚 C:其影像质量优于In-Oxine-WBC显像 D:抗生素治疗对其显像诊断的阳性率影响不大 E:上述均是

1.3³99=（）。

A:1.3³99+1.3 B:1.3³100－1.3 C:1.3³100+1.3
