まとめ
アンバーレッドカラーイメージング(ACI)は、内視鏡的粘膜下層剥離術(ESD)および経口内視鏡的食道筋層切開術(POEM)中の粘膜下血管および層の視覚化を著しく向上させます。この新しい技術は、第三腔内視鏡検査における専門家および非専門家の両方にとって明瞭さを向上させます。
科学分野:
- 消化器病学;内視鏡イメージング;外科的視覚化
背景:
- アンバーレッドカラーイメージング(ACI)は、新しい画像強調内視鏡技術です。;ACIは、血流が豊富で粘膜下の構造の視覚化を向上させることを目的としています。
研究 の 目的:
- ACIが粘膜下血管、粘膜下層、および筋層の同定を向上させるかどうかを評価すること。;臨床設定におけるACIと白色光イメージング(WLI)の比較。
主な方法:
- ESDおよびPOEMの第三腔内視鏡クリップを分析した前向きビデオベース研究。;マッチさせたWLIおよびACIセグメントをランダム化し、専門家および非専門家によって鮮明度を評価しました。;10点のリッカート尺度を使用して、血管、粘膜下層、および筋層の鮮明度を評価しました。
主要な成果:
- ACIは、非専門家(7.33から8.55)および専門家(7.96から9.63)にとって粘膜下血管の鮮明度を著しく向上させました。;ACIにより、非専門家(6.37から8.14)および専門家(7.82から9.80)にとって粘膜下層の鮮明度が向上しました。;筋層の鮮明度も、両群ともにACIにより著しく向上しました。
結論:
- ACIは、ESDおよびPOEM処置における主要構造の認識を向上させます。;ACIの利点は、専門家および非専門家の両方の内視鏡医に及びます。;ACIは、第三腔内視鏡検査に価値のある補助となります。

Endoscopic Procedures III: Video Capsule Endoscopy
843
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Color Vision
1.5K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Anatomical Positions
19.9K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Anatomical Terminology
27.1K
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Anatomical Movements
15.7K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...
