まとめ
超音波エラストグラフィーは、胸水や間質性肺疾患などの胸部疾患の診断に可能性を示していますが、臨床使用にはより標準化された研究が必要です。
科学分野:
- 医用画像処理; 胸部疾患; 診断用超音波
背景:
- 超音波エラストグラフィーは、医用画像処理で注目を集めている。 胸部疾患への応用には、さらなる定義が必要である。 経胸壁超音波検査(TUS)および気管支内超音波検査(EBUS)は、胸膜および肺の評価に使用される。
研究 の 目的:
- 胸部疾患における超音波エラストグラフィーの診断的および臨床的価値を系統的にレビューすること。 TUSおよびEBUSエラストグラフィーの胸膜および肺病変の評価における役割を評価すること。
主な方法:
- MEDLINE、EMBASE、およびCochrane Libraryを対象に、系統的な文献検索を実施した(2025年1月まで)。 TUSまたはEBUSエラストグラフィーを胸膜または肺の病状に評価した研究を含めた。 バイアスのリスクはQUADAS-2を使用して評価した。
主要な成果:
- 30件の研究が対象となった。28件はTUSエラストグラフィーを使用し、2件はEBUSを使用した。 せん断波エラストグラフィーは、悪性/良性胸水および胸膜下病変の鑑別に一般的であった。 表面波エラストグラフィーは、間質性肺疾患においてより高い硬度を示し、重症度と相関していた。 エラストグラフィーガイド下生検は、診断収率を向上させた。
結論:
- 超音波エラストグラフィーは、胸水、肺病変、および間質性肺疾患の評価に有望であり、ベッドサイドでの診断を支援し、放射線被ばくを低減する可能性がある。 方法論のばらつきと質の高い証拠の限定性は、現在のところ、広範な臨床実装を妨げている。 胸部画像診断における診断的有用性を確立するには、標準化されたプロトコルと多施設での検証が不可欠である。

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Random and Systematic Errors
14.8K
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

Systematic Sampling Method
13.0K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.

Propagation of Uncertainty from Systematic Error
1.5K
The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this...

Systematic Error: Methodological and Sampling Errors

In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...
