Summary
Cardiac computed tomography (CT) offers advanced insights into coronary arteries and atherosclerosis. New techniques like fractional flow reserve CT (FFRCT) noninvasively predict ischemia, potentially reducing the need for invasive procedures.
Area of Science:
- Cardiovascular imaging
- Radiology
- Medical diagnostics
Background:
- Cardiac computed tomography (CT) technology has advanced significantly.
- Improved spatial and temporal resolution enhance coronary artery and atherosclerosis assessment.
- Noninvasive modalities provide valuable diagnostic information.
Purpose of the Study:
- To highlight the evolving capabilities of cardiac CT.
- To discuss the role of CT in risk stratification and event prediction.
- To evaluate novel techniques like fractional flow reserve CT (FFRCT).
Main Methods:
- Utilizing advanced cardiac CT for coronary artery calcium scoring.
- Employing CT angiography for stenosis detection and plaque characterization.
- Applying fractional flow reserve CT (FFRCT) for noninvasive ischemia assessment.
Main Results:
- CT angiography demonstrates high negative predictive value for ruling out stenosis.
- FFRCT accurately predicts ischemia-causing lesions noninvasively.
- A multicenter study confirmed high concordance between FFRCT and invasive fractional flow reserve.
Conclusions:
- Cardiac CT provides comprehensive, noninvasive evaluation of coronary artery disease.
- FFRCT shows significant potential to guide clinical decisions and reduce invasive procedures.
- Advancements in cardiac CT are transforming the diagnosis and management of atherosclerosis.

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...

683
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...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
