Dual 68-Gallium/FDG PET imaging in neuroendocrine tumours

神经内分泌肿瘤(Net)是一种罕见的癌症。低级别肿瘤可能生长非常缓慢，不需要治疗，但高级别肿瘤可能会在几周内生长，预后很差。分级是通过观察组织来确定的，但即使在同一患者的不同疾病部位，这一分级也可能有很大差异。两种PET扫描(FDGPET和68Gallium PET)可以分别显示高级别和低级别的疾病，我们计划研究它们在晚期神经内分泌肿瘤成像中的联合作用。

Neuroendocrine tumours (NETs) are uncommon cancers. Low-grade tumours may grow very slowly and not require treatment, but high-grade tumours can grow over weeks and have a poor prognosis. Grade is determined by looking at tissue, but this may vary considerably even in different disease sites in the same patient. Two PET scans (FDG PET and 68Gallium PET) can show high grade and low grade disease respectively, and we plan to investigate their combination in imaging advanced neuroendocrine tumours.
