Computed Tomography01:10

Computed Tomography

9.6K
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 V: CT

581
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...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

642
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 Medicine
  • Radiology
  • Pathology

Background:

  • Computed tomography (CT) is a valuable tool in forensic medicine, complementing traditional autopsies.
  • Existing research often attributes postmortem CT findings to normal postmortem changes.
  • Interpreting these findings requires careful consideration as they can be misleading.

Purpose of the Study:

  • To illustrate common postmortem CT findings in atraumatic in-hospital deaths.
  • To identify diagnostic pitfalls associated with normal postmortem changes.
  • To differentiate true pathological lesions from postmortem artifacts on CT.

Main Methods:

  • Pictorial essay format.
  • Review of postmortem CT scans from atraumatic in-hospital deaths.
  • Correlation of imaging findings with autopsy results (implied).

Main Results:

  • Common postmortem CT findings are presented.
  • Examples of normal postmortem changes mimicking pathological lesions are shown.
  • Diagnostic challenges in differentiating artifacts from pathology are discussed.

Conclusions:

  • Postmortem CT interpretation requires awareness of normal postmortem changes.
  • Misinterpretation of postmortem changes can lead to diagnostic errors in forensic investigations.
  • Distinguishing artifacts from pathology is crucial for accurate postmortem assessment.
