An intramedullary spinal cord ependymoma was studied by positron emission tomography (PET) using (11C-methyl)-L-methionine (11C-Met). MRI showed a homogeneously enhancing tumour at C6-T2 with cysts at its rostral and caudal ends. Sagittal PET images demonstrated high 11C-Met uptake in the solid portion of the tumour, particularly ventrally at C7-T2, where viable tumour cells proliferated in association with abundant perforating vessels. Met-PET would appear useful for delineating the viable portion of intramedullary ependymomas.
利用（11C-甲基）-L-蛋氨酸（11C-Met）通过正电子发射断层扫描（PET）对一例脊髓髓内室管膜瘤进行了研究。MRI显示C6-T2水平有一个均匀强化的肿瘤，其头端和尾端有囊肿。矢状位PET图像显示肿瘤实性部分11C-Met摄取较高，尤其是在C7-T2水平的腹侧，此处有存活的肿瘤细胞与丰富的穿支血管一起增殖。Met-PET似乎有助于勾勒脊髓髓内室管膜瘤的存活部分。
