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...

Positron Emission Tomography01:29

Positron Emission Tomography

4.1K
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...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

89
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Area of Science:

  • Forensic Radiology
  • Medical Imaging
  • Radiographic Techniques

Background:

  • Postmortem computed tomography (CT) imaging protocols differ significantly from those used for living patients.
  • Standard diagnostic CT protocols are not optimized for postmortem imaging, necessitating adjustments to exposure parameters.
  • Radiation dose reduction protocols for pediatric patients are unsuitable for postmortem CT.

Purpose of the Study:

  • To outline the fundamental techniques for performing postmortem CT scans.
  • To discuss advanced scanning and post-processing methods for postmortem CT.
  • To highlight the necessary modifications in CT parameters for effective postmortem imaging.

Main Methods:

  • Altering exposure parameters to eliminate artifacts like noise and beam hardening.
  • Optimizing tissue contrast for improved visualization of postmortem tissues.
  • Employing multiple scanning sequences and advanced post-processing techniques.
  • Utilizing specialized protocols distinct from those for living patients or pediatric dose reduction.

Main Results:

  • Modified exposure parameters effectively reduce artifacts and enhance tissue contrast in postmortem CT.
  • Advanced post-processing techniques improve the detection of subtle findings.
  • Postmortem CT enables detailed visualization of structures like intracranial collections and non-displaced fractures.

Conclusions:

  • Postmortem CT requires specialized techniques and parameter adjustments compared to diagnostic CT in living individuals.
  • Optimized scanning and post-processing are crucial for accurate interpretation of postmortem CT findings.
  • These techniques enhance the identification of subtle pathological evidence in forensic cases.
