概括
这项研究评估了使用CT血管学测量表面动脉 (STA) 测量的可重现性. 虽然一些测量结果显示了观察者之间的良好一致性,但其他测量结果 (如表面积) 的复制性较差,这凸显了对标准化协议的需求.
科学领域:
- 放射学 放射学是一门学科.
- 人体解剖学 解剖学 解剖学
- 医疗成像医学成像
背景情况:
- 表面动脉 (STA) 解剖学通过剖析和成像记录得很好.
- 电脑图谱血管学是可视化STA的常见工具.
- 有限的数据存在于STA解剖评估中观察者之间的变异性.
研究的目的:
- 用CT血管学评估表面动脉 (STA) 的各种解剖学测量的可重现性.
- 评估对分类和定量STA参数的观察者间协议.
主要方法:
- 对40张头骨CT血管图扫描的回顾性分析.
- 两个读者对80个STA进行了独立评估.
- 统计分析包括kappa统计和类内相关系数 (ICC).
主要成果:

Temperature Measurement Sites
1.6K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Equipments Used to Measure Body Temperature
963
Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...
