まとめ

乳腺切除の重量は,3Dカメラで測定された体積変化と強く相関しており,外科医が対称性乳房手術を計画するのに役立ちます. この客観的な測定は,主観的な評価への依存を軽減し,外科的結果を改善します.

科学分野:

整形外科手術についてです.
メディカルイマージング (医学イメージング)
バイオメカニカルエンジニアリング

背景:

乳房手術で対称的な結果を達成することは極めて重要ですが,しばしば主観的です.
現在の手法は,外科医の経験に大きく依存しており,そのため多様性が生じています.
乳房手術の予測性と結果を改善するために,客観的なツールが必要です.

研究の目的:

切除された乳腺組織の重量と,ポータブル3Dカメラで測定された体積の変化との相関を調査する.
この相関に対する乳房密度の影響を評価する.
乳腺縮小手術の計画と評価のためのより客観的な方法を開発する.

主な方法:

双方の乳房縮小手術を受けた30人の患者が登録されました.
3Dカメラ (CreaformによるGOPRO) を使用して,手術前および手術後の4ヶ月の乳房の量を測定しました.
関連分析のためのMyotonProデバイスを使用して乳房密度を測定しました.

主要な成果:

切除重量と体積の変化の間に強い相関関係 (r2=0.822) が発見されました.
乳腺密度測定は,観察された相関に有意な影響を及ぼさなかった.
切除重量≥500gの予測モデルでは,高感度 (85.3%) と高特異性 (86.4%) の666mLの体積変動が示されました.

結論:

3Dカメラで測定可能な切除重量は,乳房手術における体積変化の強力な予測要因です.
乳腺の密度は,この関係に影響を与えないようです.
3Dカメラの日常的な使用は,手術計画を改善し,乳房縮小の美学的な結果を最適化することができます.

Numerical Calculations

1.2K

In engineering applications, the representation of the numerical value is critical. Presenting or reporting the answer is one of the essential parts of engineering practices. Numerical calculations are performed using handheld calculators or computers since numerically accurate answers are always preferred.
The solution to a problem is obtained using different methods. While manually solving algebraic symbols is one of the most common methods, the graphical method is often preferred. Computers...

Pilot and Numeric Relaying

496

Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

How Data are Classified: Numerical Data

38.6K

Data that are countable or measurable in specific units are called numerical or quantitative data. Quantitative data are always numbers. Quantitative data are the result of counting or measuring the attributes of a population. Amount of money, pulse rate, weight, number of people living in a town, and number of students who opt for statistics are examples of quantitative data.
Quantitative data may be either discrete or continuous. All quantitative data that take on only specific numerical...

Constant Volume Calorimetry

30.9K

Calorimeters are useful to determine the heat released or absorbed by a chemical reaction. Coffee cup calorimeters are designed to operate at constant (atmospheric) pressure and are convenient to measure heat flow (or enthalpy change) accompanying processes that occur in solution at constant pressure. A different type of calorimeter that operates at constant volume, colloquially known as a bomb calorimeter, is used to measure the energy produced by reactions that yield large amounts of heat and...

Volume of Distribution

1.4K

The apparent volume of distribution (Vd) is a crucial pharmacokinetic parameter representing the hypothetical body fluid volume into which a drug disperses. It is calculated based on the total amount of drug in the body (estimated from the administered dose and bioavailability) divided by the plasma drug concentration. The total amount of drug in the body does not directly refer to the dose given but is derived by accounting for absorption, distribution, metabolism, and excretion processes.

Problem Solving: Volume

The volume of a fuel tank mounted on the wing of a jet aircraft can be modeled using the concept of solids of revolution. In this case, the tank is formed by rotating a two-dimensional region, defined by a mathematical function, about the x-axis. The region extends along the axis from zero to two meters, and the resulting three-dimensional shape is symmetric about the axis of rotation. Because the boundary curve lies directly against the axis, the disk method is an appropriate technique for...
