まとめ
コンピューテッドトモグラフィー(CT)は頸椎椎間板高測定のゴールドスタンダードである。MRIおよびX線はCTと比較して系統的なバイアスを示し、CTは正確な椎間板高評価のための推奨画像検査法である。
科学分野:
- 放射線医学
- 整形外科学
- 医用画像処理
背景:
- 頸椎椎間板高は、頸椎変性椎間板疾患(CDDD)の診断と手術計画に不可欠です。
- 磁気共鳴画像法(MRI)とX線は一般的に使用されていますが、コンピューテッドトモグラフィー(CT)と比較した場合の椎間板高測定の精度は十分に確立されていません。
研究 の 目的:
- MRI、X線、CTにおける頸椎椎間板高測定の信頼性と一致性を評価すること。
- 頸椎における正確な椎間板高評価のためのゴールドスタンダード画像検査法を決定すること。
主な方法:
- 6ヶ月以内にMRI、X線、CTを受けた120人の患者を対象とした後向き研究。
- 頸椎(C2-C3からC6-C7)の中央、前方、後方の椎間板高を測定しました。
- ICCは、術者間および術者内の信頼性を評価しました。線形混合モデルを用いて結果を比較しました。
主要な成果:
- ICCは、X線で中程度から良好、MRIおよびCTで良好から極めて良好な信頼性を示しました。椎間板高の平均差は、0.1 mm(MRI vs. X線、p=0.163)、1.3 mm(MRI vs. CT、p<0.001)、1.3 mm(X線 vs. CT、p<0.001)でした。
結論:
- MRIおよびX線は、CTと比較して頸椎椎間板高測定において系統的なバイアスを示します。
- CTは、正確な頸椎椎間板高評価のための好ましい画像検査法として推奨されます。
- 椎間板高評価における最適な信頼性のためには、中央椎間板測定が推奨されます。

Imaging Studies for Cardiovascular System V: CT
307
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...

X-ray Crystallography
25.8K
The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
426
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Imaging Studies for Cardiovascular System III: X-Ray
472
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...
