Summary
For radiology education on Instagram, static image posts significantly outperform short-form videos (reels) in audience reach and engagement. Interactive image formats, like "You Make the Call!" quizzes, further enhance performance.
Area of Science:
- Medical Education
- Radiology
- Social Media Analytics
Background:
- Instagram is a popular platform for professional education.
- Short-form video (reels) is perceived as more engaging than static images.
- The effectiveness of different Instagram content formats in radiology education is not well-established.
Purpose of the Study:
- To compare the performance of static image posts versus Instagram reels for radiology education.
- To analyze engagement metrics across different content types on Instagram.
- To provide evidence-based recommendations for radiology educators using social media.
Main Methods:
- Quantitative analysis of Instagram post metrics (impressions, shares, likes, saves, comments).
- Comparison of static images (n=128) and reels (n=96) using Kruskal-Wallis test.
- Statistical analysis with Bonferroni correction for multiple comparisons.
Main Results:
- Static images achieved significantly higher impressions (18,745 vs. 11,972), shares (19 vs. 20), likes (480 vs. 296), and saves (138 vs. 84) compared to reels.
- Interactive image posts, specifically "You Make the Call!" (YMTC) quizzes, demonstrated superior performance metrics over other image types.
- Reels showed varied engagement, with YMTC reels being most liked, quiz reels receiving the most comments, and talking clips being most saved.
Conclusions:
- Static image posts are more effective than reels for radiology education on Instagram.
- Radiology educators should prioritize static image content, especially interactive formats like quizzes, to maximize audience reach and engagement.
- Further research could explore optimal content strategies for different social media platforms in medical education.

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...

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

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...

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...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
