まとめ
超高解像度超音波 (SR-US) は,重症がん患者における腫瘍の血流を迅速に評価し,緊急治療を指導します. このベッドサイドの画像は 血流の減少と 改善された結果と相関し 集中治療を向上させます
科学分野:
- 腫瘍学
- 医療用イメージング
- クリティカル ケア 医療
背景:
- 重症患者の腫瘍学的緊急事態では,腫瘍反応の迅速な評価が必要である.
- 従来のイメージング (CT,MRI) は,集中治療室 (ICU) で実行できないことが多い.
- 超解像度超音波 (SR-US) は,ベッドサイド腫瘍の微小血管評価のための有望な非侵襲的な代替手段を提供します.
研究 の 目的:
- 腫瘍 perfusion 変化のモニタリングにおけるリアルタイム SR- US 画像の臨床的有用性を評価する.
- perfusion density と flow heterogeneity のようなマイクロ血管のパラメータを定量化するためにSR-USを評価する.
主な方法:
- 緊急事態で重症の癌患者を対象とした前向きな観察研究.
- 緊急治療開始前と後のベッドサイドSR-US画像検査
- リアルタイムで船のセグメンテーションと定量分析を行うためのAI駆動データ処理
主要な成果:
- SR- USでは,治療開始から数時間以内に輸液変化が検出されました.
- 腫瘍の perfusion の減少は,臨床改善とICU 滞在の短縮と有意に相関していました.
- 30μmの微小容器が視覚化され,コントラスト微小泡で有害事象は発生しなかった.
結論:
- リアルタイムSR-USは,腫瘍血管の反応を腫瘍学的緊急事態で評価するための新しいベッドサイド法です.
- ICUケアへの統合は意思決定を改善し,静的イメージングへの依存を減らすことができます.
- パーソナライズされたがん管理をサポートし,マルチセンターの検証が必要です.

01:17Ultrasonography
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
