まとめ
新しいダブルボラス・プロネ・トゥ・サピネ・ブレスト・MRI (P2S2) プロトコルにより,シングル・セッション・イメージングが可能です. この方法は,乳がん手術の別々のイメージングセッションに匹敵する十分な腫瘍増強とマージン視覚化を提供します.
科学分野:
- 放射線学 放射線学
- 腫瘍学 腫瘍学
- メディカルイマージング (医学イメージング)
背景:
- 仰向け乳房MRIは,乳房保全手術におけるポジティブマージン率を減らすことができます.
- 横座と横座の乳房MRIセッションを別々に行うことは,臨床的にも経済的にも負担がかかります.
- シングル・セッション・プロトコルの評価は,効率の向上に不可欠です.
研究 の 目的:
- 腫瘍と繊維腺組織のコントラスト比率 (TFRs) を評価するために,単回のセッションの横向きの乳房MRIで.
- この新しいプロトコルを使用して,腫瘍のマージンの可視化を評価する.
- ダブルボラス・プロネ・トゥ・サピネMRIプロトコル (P2S2) の有効性を,別々のイメージングセッションと比較する.
主な方法:
- 39人の患者で,二重ボラス型,プロネ・トゥ・サピネMRIプロトコル (P2S2) が使用されました.
- コントロールグループ (35人の患者) は,寝転がった状態と寝転がった状態のMRIセッションを別々に受けました.
- 腫瘍と線維腺組織のコントラスト比 (TFRs) とマージン可視化が統計的に比較されました.
主要な成果:
- P2S2と独立の仰向け検査 (P = .79) の間で,平均TFRの有意な差は認められなかった.
- 放射線科医は,両方のプロトコルで腫瘍のマージンビジュアライゼーションの評価に優れた合意を示しました (κスコア1.00と0.95).
結論:
- 2回目のコントラスト注射後の単回のセッションの横の乳房MRIは,十分な腫瘍増強を提供します.
- このプロトコルは,手術前の手術指導のために腫瘍の限界を効果的に視覚化します.
- P2S2プロトコルは,独立座の乳房MRIに匹敵し,より効率的な代替案を提供します.

Margin of Error
7.7K
The margin of error is also called the maximum error of an estimate. The margin of error is the maximum possible or expected difference between the observed sample parameter value and the actual population parameter value. For proportion, it is the maximum difference between the value of sample proportion obtained from the data and the true value of population proportion. As the true value of the population parameter is not known, the margin of error is calculated using the sample statistic.

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview
6.9K
Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material, molecules absorb light depending on the energy required for...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Tumor Immunotherapy
2.0K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
