Value of Time-Density Curve in the Differentiation of Common Brain Tumors

ZHANG Shubao, LIU Yucheng, HUANG Lianqing,et al. Department of Radiology, No.1 People's Hospital, Lianyungang, Jiangsu Province 222002, P.R.China  
Objective To evaluate the time-density curve of dynamic enhanced CT scan in differential diagnosis of common brain tumors.Materials and Methods Enhanced CT scanning, with fixed slice, time, contrast velocity and dose, was performed in 46 cases with brain tumors. With CT functional software, the data were processed and the time-density curve was analyzed.Results The average peak value, enhancement altitude, peak time and curve type were different between meningiomas, gliomas and metastatic tumors. The average peak value and enhancement altitude of meningiomas was significantly different with that of gliomas or metastatic tumors (P0.01). Peak time of gliomas was significantly different with that of meningiomas or metastatic tumors (P0.01).Conclusion Time-density curve is different from tumor to tumor, it is of much value in the differential diagnosis.
