Imaging Studies for Cardiovascular System V: CT01:28

Imaging Studies for Cardiovascular System V: CT

486
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 III: X-Ray

566
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Computed Tomography

9.3K
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...

Summary

Computed tomography (CT) imaging is prone to artifacts from patient motion, technique, and unique cardiac factors. Strategies to reduce motion artifacts include optimizing heart rate, scan duration, and using advanced reconstruction algorithms.

Area of Science:

  • Medical Imaging
  • Radiology
  • Computed Tomography

Background:

  • Computed tomography (CT) is susceptible to numerous artifacts.
  • Patient- and technique-specific artifacts can impact image quality, especially in cardiac imaging.
  • Motion artifacts are the most prevalent type, stemming from patient, cardiac, or respiratory movement.

Purpose of the Study:

  • To comprehensively review common artifacts encountered in computed tomography (CT).
  • To detail the causes of various CT artifacts, including motion, partial volume averaging, beam hardening, metal, and quantum mottle.
  • To outline strategies for mitigating these artifacts to improve diagnostic accuracy.

Main Methods:

  • Review of literature on computed tomography (CT) artifacts.
  • Categorization of artifacts based on origin (patient, technique, cardiac).
  • Description of artifact reduction techniques for each category.

Main Results:

  • Motion artifacts (cardiac and respiratory) can be reduced through heart rate control, scan optimization, and advanced algorithms.
  • Partial volume averaging is mitigated by improved spatial resolution and higher x-ray energy.
  • Beam hardening, metal artifacts, and quantum mottle have specific causes and reduction strategies involving filtration, energy, positioning, and reconstruction algorithms.

Conclusions:

  • Understanding the causes of CT artifacts is crucial for effective mitigation.
  • Implementing specific technical and algorithmic adjustments can significantly reduce artifacts.
  • Optimizing CT protocols enhances image quality and diagnostic confidence in various clinical applications.
