为了评价使用18F-脱氧氟葡萄糖作为示踪剂的正电子发射断层扫描代谢图在偏盲诊断中的有用性，我们检查了8例脑血管意外患者和4例对照组。神经眼科检查显示偏盲5例，不完全偏盲3例;计算机断层扫描显示低密度区4例;核磁共振成像显示延长T2区5例。在没有视觉刺激的情况下，视皮层中葡萄糖的脑代谢率为7.4 ± 1.0 mg/min/100 g大脑，没有半球间不对称。光刺激增加大脑葡萄糖代谢率在视觉皮层的未受影响的半球和减少它在受影响的半球。完全性偏盲枕后内侧皮质代谢率不对称性为22%~ 12%（P<0.01）。
To evaluate the usefulness of metabolic mapping by positron emission tomography using18F-deoxyfluoroglucose as a tracer in the diagnosis of hemianopsia, we examined eight patients who had had cerebrovascular accident, and four controls. Neuro-ophthalmologic examination disclosed hemianopsia in five and incomplete hemianopsia in three patients; computed tomography showed low-density areas in four patients; and nuclear magnetic resonance imaging demonstrated a prolonged T2area in five patients. The cerebral metabolic rate for glucose without visual stimulation in the visual cortex was 7.4 ± 1.0 mg/min/100 g of brain without interhemispheric asymmetry. Light stimulation increased cerebral metabolic rate for glucose in the visual cortex of the nonaffected hemisphere and decreased it in the affected hemisphere. Asymmetry in the metabolic rate in the posterior medial occipital cortex in complete hemianopsia was 22% 12% (P<.01).
