Summary
Multidetector computed tomography (MDCT) accurately assesses coronary stenosis compared to invasive coronary angiography. Coronary artery calcium score did not significantly impact MDCT
Area of Science:
- Cardiovascular imaging
- Radiology
- Medical diagnostics
Background:
- Multidetector computed tomography (MDCT) is a non-invasive imaging technique.
- Invasive coronary angiography (ICA) is the gold standard for assessing coronary artery stenosis.
- The role of coronary artery calcium score (CS) in MDCT accuracy is debated.
Purpose of the Study:
- To evaluate the agreement between MDCT and ICA in diagnosing coronary stenosis.
- To determine if coronary artery calcium score influences the diagnostic accuracy of MDCT.
Main Methods:
- 266 patients underwent both 64-slice MDCT and ICA.
- Coronary stenosis was qualitatively assessed by MDCT and compared to ICA.
- Agatston score was calculated using standard software.
Main Results:
- MDCT showed good agreement with ICA in 83.05% of evaluated stenoses (Kappa = 0.684).
- Coronary artery calcium score did not significantly affect the agreement between MDCT and ICA (OR = 0.93).
- MDCT demonstrated high sensitivity, specificity, and predictive values on multiple assessment levels.
Conclusions:
- Non-invasive MDCT provides good qualitative assessment of coronary stenosis.
- Coronary artery calcium score has no significant impact on the diagnostic agreement between MDCT and ICA.

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...

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...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

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...

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...
