小児透視検査の手技別診断基準レベル:システマティックレビュー
1Diagnostic Radiology Department, College of Applied Medical Sciences, Taibah University, Al-Madinah, Saudi Arabia.
まとめ
このレビューでは、小児透視検査の診断基準レベル(DRL)に大きなばらつきがあり、インターベンショナル手技は診断手技よりも高い放射線量と透視時間を要することが判明した。
科学分野:
- 放射線医学
- 医用物理学
- 小児画像診断
背景:
- 診断基準レベル(DRL)は、小児透視検査における放射線線量を最適化するために不可欠である。
- 施設間のDRLのばらつきは、患者の安全性と実効線量に影響を与える可能性がある。
- 小児手技に関する現在のDRLデータを統合するために、系統的レビューが必要である。
研究 の 目的:
- 小児の診断およびインターベンショナル透視検査における既存の診断基準レベル(DRL)を系統的にレビューすること。
- 手技の種類、年齢、体重に基づくDRLのばらつきを分析すること。
- 小児透視検査におけるDRLの不一致に寄与する要因を特定すること。
主な方法:
- PubMed/MEDLINE、ScienceDirect、Google Scholar(2012年6月~2025年12月)の系統的文献検索。
- 小児の診断およびインターベンショナル透視検査のDRLを報告する14件の記事を含めた。
- 両方の手技の種類について、年齢別および体重別のDRLにデータを分類した。
主要な成果:
- 線量面積積(DAP)および透視時間(FT)の値に有意な異質性とばらつきが観察された。
- インターベンショナル透視検査は、診断検査と比較して実質的に高いDRLを示した。
- インターベンショナル手技における高いDRLは、FTの増加(平均9.75分対2.3分)と直接相関していた。
結論:
- 医療機関間でDRL(DAPおよびFT)に大きな差が存在する。
- 透視時間の増加は、小児インターベンショナル透視検査におけるDRL増加の主な要因である。
- 線量ばらつきを減らすために、小児透視検査プロトコルの標準化が推奨される。

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...

Inertial Frames of Reference
8.9K
Newton’s first law is usually considered to be a statement about reference frames. It provides a method for identifying a special type of reference frame: the inertial reference frame. In principle, we can make the net force on a body zero. If its velocity relative to a given frame is constant, then that frame is said to be inertial. So, by definition, an inertial reference frame is a reference frame where Newton's first law holds valid. Newton's first law applies to objects with...

Non-inertial Frames of Reference

A reference frame accelerating or decelerating relative to an inertial frame is a non-inertial frame. To help understand this, consider what taking off in an airplane, turning a corner in a car, riding a merry-go-round, and the circular motion of a tropical cyclone all have in common. All these systems are accelerating, decelerating, or rotating relative to the Earth; hence, they all are non-inertial frames. All these systems exhibit inertial forces, which merely seem to arise from motion,...

Random and Systematic Errors
15.3K
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
13.4K
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.
