Imaging Studies II: Positron Emission Tomography and Scintigraphy

83
Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Positron Emission Tomography

4.0K
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...

Computed Tomography

4.3K
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...

Background:

  • Photon-counting detector CT (PCD CT) is a novel clinical radiology technology.
  • PCD CT has not yet been widely adopted in post-mortem CT (PMCT) imaging.
  • Research on PCD CT applications in forensic and anatomical pathology is limited.

Purpose of the Study:

  • To explore the potential and limitations of PCD CT in post-mortem imaging.
  • To present technical parameters for optimal PCD CT acquisition and reconstruction in forensic cases.
  • To evaluate image quality for unenhanced whole-body PMCT examinations.

Main Methods:

  • Scanning of forensic corpses using PCD CT.
  • Development and optimization of acquisition parameters.
  • Reconstruction parameter tuning for enhanced image quality.

Main Results:

  • Excellent image quality achieved with PCD CT in PMCT.
