2、射Tc—MIBI30mCi,注射后30分鐘和120分鐘分別行早期相和延期相顯像,計算腫瘤感興趣區(qū)(regionofinterest,ROI)與對側(cè)正常相應部位早期攝取比值(T/Ne)、延期攝取比值(T/Nd)和滯留率(RI%)。所有患者給予術(shù)后病灶三維適形放療和替莫唑胺(temozolomide,TMZ)同步化療,隨后給予6個周期的TMZ輔助化療。結(jié)果放化療有效組49例(71.1%),中位生存期(MST)19月;無效組18例(28.9%),MST11月,兩者MST比較差異有統(tǒng)計學意義(P<0.05),前者T/N
3、e、T/Nd和RI%值為4.65±2.17、6.67±3.32及(16.11±2.35)%;后者為6.14±2.06、4.47±2.57及(5.40±2.61)%,T/Ne和T/Nd值比較差異無統(tǒng)計學意義(P>0.05),RI%值比較差異有統(tǒng)計學意義(P<0.05)。結(jié)論Tc—MIBI腦顯像中RI%對高分級腦膠質(zhì)瘤同步放化療療效有一定的預測作用。關(guān)鍵詞:神經(jīng)膠質(zhì)瘤;Tc—MIBI;SPECT/CT;腦顯像;藥物療法;放射療法中圖分類號:R730.264文獻標志碼:A文章編號:1001—1692(2014)o1—
