診断放射線における患者の遮蔽終了:実践中止の根拠
Journal of the Korean Society of Radiology
|December 19, 2025
まとめ
診断放射線における日常的な性腺遮蔽はもはや推奨されません。現代の画像処理はリスクを低減し、遮蔽は線量を増加させたり、詳細を不明瞭にしたりする可能性があり、歴史的な利点を上回ります。
科学分野:
- 放射線学
- 医用物理学
- 放射線防護
背景:
- 性腺遮蔽は、70年以上にわたり診断放射線学における標準的な実践でした。
- 当初は、電離放射線による遺伝的リスクを軽減するために実施されました。
- 医用画像処理における放射線防護の歴史的背景。
研究 の 目的:
- 日常的な性腺および胎児の遮蔽を中止するための科学的根拠をレビューすること。
- 患者の遮蔽実践に関する最新の世界的なガイドラインを概説すること。
- 放射線防護プロトコルにおける変更実施のための戦略を議論すること。
主な方法:
- 性腺遮蔽に関する科学的証拠の文献レビュー。
- デジタル画像処理技術と放射線量の進歩の分析。
- 診断画像処理による遺伝的リスクに関する疫学研究の検討。
主要な成果:
- デジタル画像処理により、患者の放射線量が大幅に減少しました。
- 疫学研究では、診断画像処理による有意な遺伝的リスクは示されていません。
- 遮蔽の潜在的な害(線量の増加、解剖学的構造の不明瞭化)が、現在では利点を上回っています。
結論:
- 日常的な性腺および胎児の遮蔽は、主要な国際機関によってもはや推奨されていません。
- 最適な放射線防護は、日常的な遮蔽ではなく、正当化とプロトコルの最適化に依存します。
- 日常的な遮蔽の中止は、効果的な実施のために教育とコミュニケーションを必要とします。

Transmission-based Precautions II: Airborne and Protective Environment
1.8K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

PPE Use in Healthcare Settings II: Doffing
1.5K
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Standard Precaution
2.7K
Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.

Personal Protective Equipment
2.1K
Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:

PPE Use in Healthcare Settings I: Donning
1.6K
Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...
