Visualization of Myocardial Infarction in Postmortem Multiphase Computed Tomography Angiography: A Feasibility Study
The American Journal of Forensic Medicine and Pathology
|February 14, 2018
Summary
Multiphase postmortem computed tomography angiography (MPMCTA) detects myocardial infarction by identifying pathological enhancement in heart muscle. This technique aids in determining the cause of sudden cardiac death and guides autopsy sampling for histology.
Area of Science:
- Forensic Pathology
- Cardiovascular Imaging
- Radiology
Background:
- Multiphase postmortem computed tomography angiography (MPMCTA) has shown potential in detecting myocardial infarction.
- Pathological myocardial enhancement on MPMCTA may correlate with histological infarction sites.
Purpose of the Study:
- To verify the hypothesis that MPMCTA can detect pathological myocardial enhancement in cases of myocardial infarction.
- To assess the utility of MPMCTA in identifying infarction regions for guiding histological examination.
Main Methods:
- MPMCTA was performed on 10 autopsy cases with myocardial infarction and 10 control cases of non-cardiac death.
- Image analysis focused on detecting pathological myocardial enhancement.
Main Results:
- All cardiac death cases exhibited myocardial enhancement on MPMCTA in regions consistent with histological infarction.
- No myocardial enhancement was observed in the control group.
Conclusions:
- MPMCTA effectively identifies myocardial infarction, correlating imaging findings with histology.
- MPMCTA can assist in determining the cause of sudden cardiac death and improve targeted tissue sampling for microscopic analysis.

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...

Traverse angle computations are a critical component of surveying, used to compute the internal angles within a closed traverse. A traverse consists of a series of connected lines forming a closed loop, often used for land boundary delineation or mapping. Calculating the internal angles ensures accuracy in the traverse geometry and is essential for checking survey data integrity.The process begins with known azimuths and bearings of the traverse sides. Internal angles at each vertex are...

The alternative coordinate method, also known as the Shoelace Formula, is a technique for determining the area of a traverse using Cartesian coordinates. This method relies on the sequential arrangement of x and y coordinates for each point of the shape, ensuring accuracy and ease of application.In this approach, each corner's x and y coordinates are listed as fractions, with the x-coordinate as the numerator and the y-coordinate as the denominator. These coordinates are arranged sequentially...

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...
