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...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

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...

Area of Science:

  • Vascular Surgery
  • Medical Imaging
  • Biomedical Engineering

Background:

  • Endovascular stent-grafts are increasingly used for aortic arch pathologies.
  • Accurate anatomical data is crucial for device design and procedural success.

Purpose of the Study:

  • To map aortic arch diameters, branch orientations, and center line distances.
  • To propose a prototype design for a standardized stent-graft based on anatomical measurements.

Main Methods:

  • Morphological assessment of computed tomography (CT) scans from 45 patients using TeraRecon 3D imaging software.
  • 13 measurements were taken, including diameters, distances, and branch vessel orientations relative to the center line.

Main Results:

  • Proximal aortic arch diameters (2-4 cm distal to coronary artery) commonly measured 32 mm and 34 mm.
  • Distances between arch branches: innominate to left common carotid (5-6 mm), left common carotid to left subclavian (8 mm).
  • Left common carotid artery was most commonly anterior to other branches by 3-5 mm.

Conclusions:

  • Anatomical measurements provide valuable data for advancing minimally invasive aortic arch repair.
  • A standardized off-the-shelf stent-graft is proposed, suitable for the majority of patients based on common measurements.
