Computed Tomography01:10

Computed Tomography

9.3K
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...

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...

Positron Emission Tomography

8.0K
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...

Area of Science:

  • Neuroradiology
  • Oncology
  • Medical Imaging

Background:

  • Intracranial tumours represent a significant diagnostic challenge.
  • Gliomas are a common type of primary brain tumour.
  • Accurate grading of glioma malignancy is crucial for treatment planning.

Purpose of the Study:

  • To evaluate the diagnostic utility of computerised tomography (CT) in assessing intracranial tumours.
  • To investigate the correlation between CT imaging characteristics (morphology, contrast enhancement) and glioma malignancy grade.
  • To determine the reliability of CT in grading gliomas.

Main Methods:

  • Retrospective analysis of 106 intracranial tumour cases.
  • Histological confirmation of 42 glioma cases.
  • Detailed assessment of CT imaging features, including pre- and post-contrast enhancement patterns.

Main Results:

  • Gliomas were confirmed in 39.6% of the evaluated intracranial tumours.
  • A spectrum of CT imaging patterns was observed in gliomas.
  • CT appearance demonstrated a reliable correlation with glioma malignancy grade.

Conclusions:

  • Computerised tomography is a valuable tool for the initial assessment of intracranial tumours.
  • CT imaging characteristics, particularly morphology and contrast enhancement, provide reliable information for grading glioma malignancy.
  • This study supports the use of CT in predicting glioma grade, aiding clinical decision-making.
