- 医疗成像医学成像
背景情况:
- 发烧可以通过影响正常组织代谢来干扰瘤的18F-FDG PET/CT成像.
- 了解这些代谢变化对于准确的瘤识别和疗效评估至关重要.
研究的目的:
- 为了研究发烧对关键器官葡萄糖代谢的影响,使用18F-FDG PET/CT.
- 分析定量参数,特别是标准化摄入值以瘦体质量 (SUL) 规范化,在发烧患者中与无发烧对照进行比较.
主要方法:
- 对30名源不明发烧患者和24名无发烧对照患者的18F-FDG PET/CT扫描进行了回顾性分析.
- 测量SULmax和SULmean在两个组的中血池,肝脏,脏和骨髓中.
- 使用独立样本t测试或Wilcoxon-Mann-Whitney测试进行统计比较.
主要成果:
- 在发烧组中,肝脏SULmax和SULmean显著降低 (p=0.001,0.013).
- 和骨髓SULmax和SULmean在发烧组显著更高 (p<0.05).
- 在发烧组中,中血池SULmax较低 (p=0.007),但SULmean没有显著差异 (p=0.221).
结论:
- 根据SUL测量,发烧显著改变了肝脏,脏和骨髓中的葡萄糖代谢.
- 由于中血池SULmean没有显著差异,这表明它有可能成为一个稳定的参考参数.

01:25Increased Body Temperature
614
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

01:22Methods of reducing fever
612
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

01:29Decreased Body Temperature
576
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...
