Summary
Electrocardiogram-gated coronary multislice computed tomography (CT) angiography offers noninvasive imaging of coronary arteries. This advanced CT angiography is valuable for assessing coronary artery disease, bypass graft patency, and congenital anomalies, despite needing further resolution improvements.
Area of Science:
- Cardiovascular imaging
- Radiology
- Medical technology
Background:
- Coronary multislice CT angiography has advanced significantly with improved scanner technology.
- This technique enables noninvasive visualization of coronary arteries.
Purpose of the Study:
- To review the principles, techniques, applications, and artifacts of coronary multislice CT angiography.
- To highlight its diagnostic performance and limitations.
Main Methods:
- Review of current literature on electrocardiogram-gated coronary multislice CT angiography.
- Discussion of technological advancements in CT scanners (gantry speed, detector rows).
Main Results:
- Coronary CT angiography effectively evaluates coronary plaques, stenosis, bypass graft patency, and congenital anomalies.
- It visualizes coronary artery walls, lumen, and provides volumetric data for cardiac and extracardiac abnormalities.
- High negative predictive value makes it useful for low-to-intermediate risk patients.
Conclusions:
- Coronary multislice CT angiography is a valuable diagnostic tool for coronary artery disease evaluation.
- Further advancements are needed for imaging small stents, noncalcified plaques, and overcoming artifacts from arrhythmias and calcifications.

01:28Imaging Studies for Cardiovascular System V: CT
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...
01:10Computed Tomography
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...

01:25Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
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...
01:21Imaging Studies for Cardiovascular System IV: CMRI
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,...

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...
