Computed Tomography01:10

Computed Tomography

9.4K
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...

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...

X-ray Imaging

11.0K
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Imaging Studies for Cardiovascular System III: X-Ray

600
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 anthropology
  • Radiology
  • Human identification

Background:

  • Gender determination is vital in forensic medicine for human identification.
  • Mandibular morphology plays a role in sex differentiation.

Purpose of the Study:

  • To assess gender differentiation using cone beam computed tomography (CBCT) of the mandibular sigmoid notch, coronoid process, and condylar process.
  • To analyze morphometric variations in specific mandibular landmarks for sex determination in the Gujarat population.

Main Methods:

  • Analysis of CBCT scans from 100 subjects.
  • Evaluation of condyle and sigmoid notch shapes on both sides for male and female individuals.

Main Results:

  • The most common condyle shape observed in both sexes was round.
  • The sigmoid notch was predominantly round, followed by wide and sloping shapes, particularly noted in males and on the right side in females.

Conclusions:

  • CBCT imaging reveals morphometric variations in the mandibular condyle and sigmoid notch.
  • These variations show potential for individual identification and gender determination in forensic contexts.
