(F) fluorodeoxyglucose brain positron emission tomography and statistical mapping analysis, such as three-dimensional stereotactic surface projections, have been used widely for the evaluation of dementia patients. We present an unusual focal artifact on the statistical maps resulting from intense temporal muscle uptake in a patient with Alzheimer's disease. Various degrees of physiologic uptake can be seen in head and neck muscles. However, it is unusual to see a focal artifact on the statistical maps due to temporal muscle uptake. This case illustrates the importance of quality control of imaging processing when atypical findings are seen on statistical maps.
（F）氟脱氧葡萄糖脑正电子发射断层扫描及统计图谱分析，如三维立体定向表面投影，已广泛用于痴呆患者的评估。我们报告了1例阿尔茨海默病患者因颞肌摄取强烈而在统计图谱上出现的不寻常局灶性伪影。头颈部肌肉可见不同程度的生理性摄取。然而，因颞肌摄取而在统计图谱上出现局灶性伪影并不常见。该病例说明了在统计图谱上出现非典型表现时影像处理质量控制的重要性。
