Computed Tomography

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 III: X-Ray

Imaging Studies for Cardiovascular System III: X-Ray

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...

Area of Science:

Forensic medicine
Radiology
Medical imaging analysis

Background:

Coronary computed tomography (CT) angiography is valuable for evaluating coronary artery lesions.
Highly calcified lesions pose challenges due to blooming and partial volume artifacts, leading to overestimation of stenosis.
Current clinical practice uses subtraction methods to mitigate calcification issues.

Purpose of the Study:

To describe a novel calcification subtraction method for postmortem coronary CT angiography.
To enhance the accuracy of lumen evaluation in the presence of severe coronary calcification.
To improve lesion retrieval and diagnostic reliability in forensic pathology.

Main Methods:

Development of a calcification subtraction technique using image analysis software.
Reconstruction of CT images with a narrower field of view and bone kernel for higher spatial resolution.
Application of the subtraction method to postmortem coronary CT angiography specimens with severe calcification.

Main Results:

The subtraction method successfully removed calcification artifacts, enabling clear lumen visualization.
Accurate evaluation of lumen patency and stenosis degree was achieved, even in highly calcified lesions.
Morphological findings from CT analysis closely matched macroscopic observations.

Conclusions:

The described calcification subtraction method is effective for postmortem coronary CT angiography.
This technique overcomes limitations of traditional CT angiography in evaluating calcified coronary arteries.
The method offers a more rapid and reliable approach for forensic investigations involving coronary artery disease.
