Imaging Studies I: CT and MRI

247
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...

Magnetic Resonance Imaging

5.2K
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Area of Science:

  • Pediatric Radiology
  • Medical Informatics
  • Child Psychology

Background:

  • Magnetic resonance imaging (MRI) is crucial for pediatric diagnostics but often causes anxiety in children.
  • This anxiety can lead to poor image quality and necessitate sedation or general anesthesia, posing risks.
  • Current preparation methods may be insufficient for young patients.

Purpose of the Study:

  • To evaluate the efficacy of the COSMO@home smartphone application in preparing children for MRI scans.
  • To assess the app's impact on reducing anxiety and the need for sedation or anesthesia.
  • To determine parent and child satisfaction with the app.

Main Methods:

  • A multicenter study involved 82 children aged 4-10 years using the COSMO@home app for MRI preparation.
  • The app featured mini-games and a storyline to educate children about the MRI procedure.
  • Anxiety levels were measured using questionnaires at baseline, pre-scan, and post-scan for two age groups (4-6 and 7-10 years).

Main Results:

  • 95% of participants achieved high-quality MRI images.
  • The app was well-received by children and parents with minimal technical issues.
  • While anxiety increased pre-scan in the 4-6 age group, no significant increase was noted in the 7-10 age group.

Conclusions:

  • The COSMO@home app is a valuable tool for preparing children for MRI scans, improving patient experience.
  • It demonstrates potential to reduce sedation/anesthesia requirements in pediatric MRI.
  • Combining the app with minimal in-person guidance offers an effective alternative to traditional preparation methods.
