Summary
This case study shows how multidetector row computed tomography (MDCT) and Color Code Plaque (CCP) analysis can identify vulnerable plaques. Lipid-lowering therapy stabilized plaque, improving outcomes and predicting acute coronary syndrome.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Coronary artery disease management requires accurate plaque characterization.
- Noninvasive imaging modalities are crucial for assessing vulnerable plaques.
Observation:
- A 61-year-old woman presented with chest pain, diagnosed with vasospastic angina.
- Initial 64-slice multidetector row computed tomography (MDCT) revealed a 50% stenosis with soft plaque morphology.
- Transient ST-elevation during echocardiography prompted emergency coronary angiography, confirming the stenosis.
Findings:
- Lipid-lowering therapy with atorvastatin led to symptom improvement and reduced cholesterol levels.
- Follow-up MDCT showed plaque morphology changed from soft to intermediate, with improved vessel remodeling.
- Color Code Plaque (CCP) analysis by MDCT proved effective for plaque characterization and stabilization assessment.
Implications:
- MDCT and CCP analysis can differentiate between vulnerable and stable plaques.
- This approach aids in predicting and potentially preventing acute coronary syndrome.
- Noninvasive plaque characterization can guide therapeutic strategies in coronary artery disease.

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...
01:28Imaging 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...

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...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
