Imaging Studies for Cardiovascular System V: CT01:28

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...
Computed Tomography01:10

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...

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...

Acute Coronary Syndrome III: Diagnostic Studies

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...

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...
Imaging Studies for Cardiovascular System IV: CMRI01:21

Imaging 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,...

Area of Science:

  • Cardiovascular Imaging
  • Medical Diagnostics
  • Surgical Assessment

Background:

  • Coronary artery bypass grafting (CABG) is a common procedure for coronary artery disease.
  • Graft patency is crucial for long-term CABG success.
  • Accurate post-operative graft assessment is essential for patient management.

Purpose of the Study:

  • To compare the diagnostic performance of multi-detector computed tomography (MDCT) with conventional coronary angiography.
  • To evaluate MDCT's accuracy in detecting graft occlusion and stenosis after CABG.
  • To assess the clinical utility of MDCT as a less invasive imaging modality.

Main Methods:

  • A comparative study involving 60 patients who underwent CABG.
  • Evaluation of 135 bypass grafts and 210 graft anastomoses.
  • Analysis of diagnostic power, including sensitivity, specificity, and predictive values for MDCT versus conventional angiography.

Main Results:

  • MDCT demonstrated high diagnostic power for graft occlusion (100% sensitivity, 98.5% specificity).
  • MDCT showed high diagnostic power for graft anastomosis stenosis (100% sensitivity, 95.1% specificity).
  • No significant differences in occlusion rates were observed among graft types.

Conclusions:

  • MDCT is a highly accurate and less invasive imaging tool for evaluating coronary artery bypass grafts.
  • MDCT provides reliable assessment of graft occlusion and stenosis, serving as a viable alternative to conventional angiography.
  • The findings support the use of MDCT in routine post-CABG follow-up.
