まとめ
人工知能(AI)は、画像解析および予測タスクにおいて、血管内治療放射線科(VIR)で大きな可能性を示しています。患者ケアへの責任ある統合には、さらなる研究と協力が不可欠です。
科学分野:
- 放射線科;医用画像処理;人工知能
背景:
- AIは診断放射線科で優れていますが、データのばらつきによりVIRへの応用は限定的です。
- 血管内治療放射線科(VIR)の手順では、複雑な画像解析がしばしば伴います。
研究 の 目的:
- 術前、術中、術後のVIR段階全体にわたるAIの応用をレビューすること。
- さまざまな画像モダリティを使用して、患者ケアに対するAIの影響を評価すること。
主な方法:
- PubMed、Embase、およびWeb of Scienceの包括的な文献検索。
- AI研究を画像モダリティ(CT、MRI、透視/DSA、超音波、X線、マルチモーダル)およびタスクタイプ(セグメンテーション、検出、予測)別に分類しました。
主要な成果:
- 深層学習は、解剖学的構造のセグメンテーション(例:動脈瘤)において高い精度(0.82-0.962)を達成しました。
- AI検出タスクは、高いパフォーマンスを示しました(例:エンドリーク検出で95%の精度、狭窄で0.97のAUC)。
- 予測モデル(AUC > 0.90)は、EVAR、TEVAR、TACE、TARE後の転帰において臨床評価を上回りました。
結論:
- AIはVIRにおいて、特に治療応答のためのレディオミクスと機械学習により、変革の可能性を示しています。
- 課題には、データの制限、バイアス、および解釈可能性が含まれます。
- インターベンショナルラジオロジーにおける安全かつ効果的な展開には、臨床医とAI専門家の協力が不可欠です。

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Imaging Studies for Cardiovascular System IV: CMRI
307
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Radiological Investigation II: MRI and Ventilation Perfusion Scan
521
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...

Imaging Studies for Cardiovascular System III: X-Ray
462
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
