Abstract:
Objective To study the characteristics of dynamic susceptibility-contrast(DSC)MR perfusion curves,color images and perfusion values in pre-operative brain metastasis.Methods Twenty- eight brain metastases underwent DSC MR perfusion imaging by using a first-pass T_2~* echo-planar sequence. The patients' data were transferred to on-line workstation.Time-signal intensity curves,color perfusion maps and rCBV,rMTT values in both tumor parenchyma and peri-tumor edema were analyzed,and independent t- test was used and P0.05).Conclusion Different originated brain metastases have nearly same characteristics in DSC MR perfusion imaging.
