Insights

Coronary artery stenosis is linked to blockages in the head and neck arteries. Computed tomographic angiography confirms this association, highlighting a connection between coronary and cerebrovascular disease.

Area of Science:

  • Cardiovascular Imaging
  • Neurology
  • Vascular Medicine

Background:

  • Atherosclerosis can affect multiple arterial beds simultaneously.
  • Coronary artery disease (CAD) and cerebrovascular disease (CVD) share common risk factors.
  • The relationship between coronary artery stenosis and intracranial/extracranial artery stenosis requires further investigation.

Purpose of the Study:

  • To assess the correlation between coronary artery stenosis and stenosis in the internal carotid artery (ICA), vertebral artery (VA), and basilar artery (BA).
  • To determine the utility of computed tomographic angiography (CTA) in evaluating these vascular relationships.

Main Methods:

  • Retrospective analysis of imaging and clinical data from 84 patients who underwent CTA of the coronary arteries, head, and neck.
  • Quantification of coronary artery stenosis using segment stenosis scoring.
  • Analysis of the relationship between coronary segment stenosis scores and the degree of stenosis in the ICA, VA, and BA.

Main Results:

  • A significant positive correlation was found between coronary segment stenosis scores and the degree of stenosis in the internal carotid artery (r=0.450, P<0.05).
  • A significant positive correlation was observed between coronary segment stenosis scores and the degree of stenosis in the vertebral and basilar arteries (r=0.475, P<0.05).

Conclusions:

  • The degree of coronary artery stenosis is associated with the degree of stenosis in the internal carotid, vertebral, and basilar arteries.
  • Computed tomographic angiography is a valuable tool for confirming the relationship between coronary and cerebrovascular artery stenosis.

Imaging 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...

Imaging 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...

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Computed 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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

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...
