Computed Tomography01:10

Computed Tomography

9.0K
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

7.8K
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:

  • Medical Imaging Technology
  • Health Systems Research

Background:

  • Computed tomography (CT) is a vital diagnostic tool.
  • Understanding the productivity and market supply of CT models is crucial for healthcare access.

Purpose of the Study:

  • To evaluate the productivity of computed tomography (CT) models.
  • To characterize the global market supply of entry-level CT scanners.

Main Methods:

  • CT exam times were measured across six stages in Brazilian health facilities.
  • Productivity was calculated by comparing weekly working time to total exam time.
  • An internet search identified global manufacturers and their entry-level CT models.

Main Results:

  • Exam time variations were minimal and primarily due to non-acquisition stages.
  • Entry-level CT models offered globally include 2- to 4-slice (Asia, South America, Africa) and single-slice options.
  • US market shows models below 16-slice.

Conclusions:

  • CT scanner productivity does not scale linearly with the number of slices.
  • Shareable platforms could reduce CT costs and improve availability.
