CHEN Jiansheng, LIU Yulin, CHEN Xian,et al. Department of Radiology, Hubei Province Cancer Hospital, Wuhan 430079, P. R. China  
Objective To discuss the technique of MSCT (Multi-slice CT) perfusion for nasophargeal carcinoma.Materials and Methods 22 patients of NPC proved pathology were underwent with MSCT perfusion, a continuous scan in same position were done with 4×5mm sections every 1.5 second for a duration of 45 seconds. The perfusion data of tumor and uninvolved lateralpterygoid muscle were recorded to calculate density-time curve and perfusion indexes using function CT software.Results The mean value of blood flow (BF), peak enhancement index (PEI), time to peak (TTP) and blood volume (BV) were 51.7±(10.9) ml/100g/min, 35.4±5.2 HU, 14.5±1.7s, 853.6±245.3 ml/100g, respectively. The rates of tumor and muscle were 7.0±1.8, 4.1±1.4, 0.6±0.1, 6.9±3.9, respectively. Conclusion The correct technique is guarantee for CT perfusion, the MSCT perfusion data can reflect the character of micro-vessel of nasophargeal carcinoma.
