Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

572
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 V: CT

409
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...

Acute Coronary Syndrome III: Diagnostic Studies

321
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...

Summary

Assessing collateral circulation in acute ischemic stroke is crucial. Evaluating anterior cerebral artery-middle cerebral artery and posterior cerebral artery-MCA collaterals separately on computed tomography angiography (CTA) improves infarct volume prediction.

Area of Science:

  • Neurology
  • Radiology
  • Vascular Imaging

Background:

  • Collateral circulation plays a vital role in acute ischemic stroke outcomes.
  • Accurate assessment of collateral status is essential for guiding treatment decisions.

Purpose of the Study:

  • To measure pial collateral filling on single-phase computed tomography angiograms (sCTAs) in acute ischemic stroke.
  • To correlate these findings with established scoring systems like the CTA-based Massachusetts General Hospital (MGH) score and the digital subtraction angiography (DSA)-based American Society of Interventional and Therapeutic Neuroradiology (ASITN) score.

Main Methods:

  • Patients with acute ischemic stroke and M1 MCA±intracranial internal carotid artery occlusion were included.
  • Collateral status was assessed using the Calgary Collateral (CC) Score, MGH score, and ASITN score.
  • Infarct volumes were measured on follow-up imaging.

Main Results:

  • The Calgary Collateral (CC) Score demonstrated better prediction of follow-up infarct volumes compared to the MGH score.
  • Correlations between anterior cerebral artery (ACA)-MCA collaterals and the MGH score were strong, while posterior cerebral artery (PCA)-MCA correlations were modest.
  • The CC score showed regional variability in collateral assessment, with ACA-MCA and PCA-MCA collaterals explaining only 32% of variance.

Conclusions:

  • Collateral assessment in acute ischemic stroke is optimized using CTA with temporal resolution.
  • Evaluating regional collateral variability, specifically ACA-MCA and MCA-PCA territories separately, is recommended.
  • This approach enhances the prediction of infarct progression.
