# A Comparison of Quality and Reliability of YouTube Videos About the MRI Technique and Its Various Aspects

## TL;DR

This study evaluates the quality and reliability of YouTube videos about MRI machines and procedures, finding no significant differences between uploaders.

## Contribution

The study introduces a comparative analysis of MRI-related YouTube videos using specific quality and reliability metrics.

## Key findings

- No significant differences in video quality or reliability were found between different types of uploaders.
- Clinician- and hospital-uploaded videos were noted for providing high-quality and reliable information.
- Statistical tests showed p-values above 0.05 for all metrics, indicating no significant variation.

## Abstract

Introduction: The Magnetic Resonance Imaging (MRI) machine is a subset of nuclear magnetic resonance imaging technology that produces images of the body using magnetic field gradients. The MRI Machine has two components: the computer-based control centre room and the adjacent MRI machine room where the patient undergoes the scan.

Aims: This study aimed to assess the quality and reliability of YouTube videos about MRI machines, MRI scans, and MRI claustrophobia and compare the quality and reliability of the videos among different types of uploaders.

Methodology: The YouTube Search Algorithm and a Google Sheets questionnaire were used to evaluate 10 videos that satisfied the inclusion criteria of the study. The video analytics included were title, number of views, likes and dislikes, comments, duration, source, and content. The quality of each video was established using the Global Quality Score (GQS), Reliability Score, and Video Power Index (VPI), where each quantifier went through statistical analysis using SPSS software, version 21.0 (IBM Corp., Armonk, NY) to determine if there was any significance.

Results: In order to determine statistical differences between the groups, the Kruskal-Wallis test was used on the quantifiers GQS, reliability score, and VPI to generate p-values. The p-value for VPI is 0.467, GQS is 0.277, and reliability is 0.316. All the p-values are greater than 0.05, showing that there is no statistical support for any significant difference between the groups in their VPI, GQS and reliability scores.

Conclusions: YouTube videos with high-quality and reliable information on MRI machines, MRI procedures, and claustrophobia, especially those uploaded by clinicians and hospitals, can provide correct information, helping patients decide to undergo these procedures and alleviate claustrophobia.
