Imaging Studies for Cardiovascular System V: CT01:28

Imaging Studies for Cardiovascular System V: CT

529
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 IV: CMRI

511
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,...

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...

Computed Tomography01:10

Computed Tomography

9.4K
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...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Area of Science:

  • Biomedical Imaging
  • Comparative Anatomy
  • Radiology

Background:

  • Cadaver-based angiography studies commonly use barium sulfate and lead oxide contrast media.
  • A comparison of these agents for optimal vessel visualization and measurement in embalmed specimens is lacking.

Purpose of the Study:

  • To compare the efficacy of barium sulfate-resin, barium sulfate-gelatin, and lead oxide-milk powder as contrast agents for micro-computed tomography (CT) angiography in embalmed rat lower limb vessels.

Main Methods:

  • Micro-CT angiography was performed on embalmed Wistar rat lower limbs and cannulae injected with different contrast agents.
  • Vessel branching generations were counted, and cannula diameters were measured to assess accuracy, bias, and variance.
  • Intra- and inter-observer reliability were evaluated using intra-class correlation coefficients.

Main Results:

  • No significant difference in the number of branching generations was found between barium sulfate-resin and lead oxide-milk powder.
  • Barium sulfate-resin exhibited less bias and variance in diameter measurements compared to lead oxide-milk powder.
  • Barium sulfate-resin demonstrated superior accuracy for high-resolution micro-CT scans.

Conclusions:

  • Barium sulfate-resin is a more accurate and preferred non-toxic contrast agent for high-resolution micro-CT angiography in embalmed specimens.
  • This comparative study provides valuable insights for selecting contrast media in anatomical and research applications.
  • The described technique is applicable to various embalmed specimen models for detailed vascular analysis.
