Computed Tomography01:10

Computed Tomography

4.4K
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 III: X-Ray

162
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...

Imaging Studies for Cardiovascular System II:Types of Echocardiography

239
Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Imaging Studies for Cardiovascular System I:Echocardiography

306
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...

Electron Microscope Tomography and Single-particle Reconstruction01:07

Electron Microscope Tomography and Single-particle Reconstruction

2.4K
Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

Area of Science:

  • Cardiovascular Imaging
  • Infective Endocarditis Diagnosis
  • Radiology

Background:

  • Imaging is crucial for diagnosing and managing infective endocarditis (IE), as per recent guidelines.
  • Echocardiography is the primary imaging modality for IE.
  • Computed tomography (CT) plays a significant role, especially for prosthetic valves and complex cases.

Purpose of the Study:

  • To review the current applications of CT in the diagnosis and management of infective endocarditis.
  • To focus on CT's role in image acquisition, reconstruction, interpretation, and diagnostic accuracy.
  • To highlight CT's advantages in specific IE scenarios where echocardiography may be limited.

Main Methods:

  • Review of current literature and guidelines regarding CT in infective endocarditis.
  • Analysis of CT's diagnostic performance compared to echocardiography for valvular and paravalvular lesions.
  • Discussion of CT's utility in detecting extracardiac manifestations and surgical planning.

Main Results:

  • Echocardiography shows higher accuracy for valvular lesions, while CT excels in diagnosing paravalvular and periprosthetic complications.
  • CT is recommended for native and prosthetic valve endocarditis, particularly when echocardiography is inconclusive.
  • CT is valuable for identifying extracardiac disease and assessing coronary arteries for surgical planning.

Conclusions:

  • CT is an indispensable tool in the comprehensive evaluation of infective endocarditis, offering complementary information to echocardiography.
  • The development of photon-counting CT is expected to further expand CT's utility in IE diagnosis.
  • CT's role encompasses detection of valvular and paravalvular disease, extracardiac complications, and surgical guidance.
