Abstract:
Objective To study the value of CT perfusion in differential diagnosis of local recur and local radiofibrosis of nasopharyngeal carcinoma(NPC) at pre-and post-radiotherapy.Methods Dynamic CT scan was performed in 71 objectives: 14 in local recur group,22 in radiofibrosis group,15 in pre-radiotherapy NPC group and 20 in control group,the time-density curve(TDC) and the data of perfusion parameters were recorded and analyzed statistically.Results The TDC feature between local recur group,pre-radiotherapy NPC group and radiofibrosis group,control group had difference.The average of blood flow(BF) had significant differences by two by two comparison in four groups(P
