Radiopaedia is a wiki-based international collaborative educational web resource containing a radiology encyclopedia and imaging case repository. [1] It is currently the largest freely available radiology related resource in the world with more than 50,000 patient cases and over 16,000 reference articles on radiology-related topics. The open edit nature of articles allows radiologists, radiology trainees, radiographers, sonographers, and other healthcare professionals interested in medical imaging to refine most content through time. An editorial board peer reviews all contributions. [2]

Background

Radiopaedia was started as a past-time project to store radiology notes and cases online by the Australian neuroradiologist Associate Professor Frank Gaillard in December 2005, while he was a radiology resident. He later became passionate in building the website and decided to release it on the web, advocating free dissemination of knowledge. [3] [4] Frank initially built a Linux server to host the site. [5] The site was initially programmed using MediaWiki, the same program platform as Wikipedia, but now runs on a bespoke code written by TrikeApps. [6]

The domain name for radiopaedia.org was registered on 11 January 2007. [7]

The Radiopaedia.org platform and text content are owned by Radiopaedia Australia Pty Ltd, a privately held company for which Gaillard is the chief executive officer. [8] One of its investors is Investling and its revenue derives from ads, courses, and paid supporters. [9] [10] For image content, contributors reserve some rights and license the content to Radiopaedia and its users under a Creative Commons license. [8]

In 2010, almost all of the article and image collection from radswiki (a similar wiki-based radiology educational site) was donated to Radiopaedia. [11]

Its article content is currently limited to English.

Purpose

Radiopaedia’s mission is "to create the best radiology reference the world has ever seen and to make it available for free, for ever, for all." [12] Its intention is to benefit the radiology community and wider society and it relies on benevolent collaborations from radiologists and others with an interest in medical imaging.

Similarly to Wikipedia, registered users of the site are allowed to freely add and edit the majority of the content. This allows content to be progressively upgraded over years and for radiologists and society, in general, to continuously refine article content through time. The site also allows registered users to maintain their own personal case library of teaching cases. [13] Rather than individually publishing articles, users are encouraged to integrate content with links to cases and journal articles and collaboratively refine content. [14] In an attempt to reduce vandalism and to peer-review content, an editorial board moderates changes to ensure that the presented material is as accurate and relevant as possible. [15] As with similar open edit sites, unreliability of content has been a concern;[ citation needed ] however, despite its open edit nature, it is ranked relatively high among user reviews. [16] [17]

A survey done in 2020 shows that 90% of on-call radiology trainees in the United States are using Radiopedia and StatDx as the first and second line options to help them during their work. [18] Educational benefit was also demonstrated when integrating Radiopedia-based training in medical curriculum. [19]

Sub sites

Radiopaedia also maintains several other educational subsites which include

Editorial team

The editorial team, develop as well as help users to maintain the high-quality content of the website. [15]

The current editorial board (2021) is composed of individuals from a variety of countries and includes: [20]

Community director

iOS apps

In 2009, the first Radiopaedia iOS app series was released in two volumes. These apps package cases and articles for users to review and have sample questions and answers. [21] [22] More volumes were released subsequently. [23]

All the iOS apps were discontinued after March 2018. Instead, cases in the iOS apps exist in the form of "iOS case packs" playlists on the website. [24]

In 2019, nine out of 163 medical students surveyed in a single institution in Canada stated that they would use a radiology app for mobile learning such as "Figure 1", "Night in the ED" and "Radiopaedia" and will be willing to pay for a radiology app. [25]

Radiology is the medical specialty that uses medical imaging to diagnose diseases and guide their treatment, within the bodies of humans and other animals. It began with radiography, but today it includes all imaging modalities, including those that use no ionizing electromagnetic radiation, as well as others that do, such as computed tomography (CT), fluoroscopy, and nuclear medicine including positron emission tomography (PET). Interventional radiology is the performance of usually minimally invasive medical procedures with the guidance of imaging technologies such as those mentioned above.

The gestational sac is the large cavity of fluid surrounding the embryo. During early embryogenesis, it consists of the extraembryonic coelom, also called the chorionic cavity. The gestational sac is normally contained within the uterus. It is the only available structure that can be used to determine if an intrauterine pregnancy exists until the embryo can be identified.

<span class="mw-page-title-main">Tornwaldt cyst</span> Medical condition

A Tornwaldt cyst also spelt as Thornwaldt or Thornwald cyst is a benign cyst located in the upper posterior nasopharynx. It was first described by Gustav Ludwig Tornwaldt. It can be seen on computed tomography (CT) or magnetic resonance imaging (MRI) of the head as a well-circumscribed round mass lying in the midline. In most cases, treatment is not necessary. Indications for treatment include symptomatic lesions, large lesions (>1 cm), or lesions adjacent to the eustachian tube orifice.

Fogging phenomenon in computerized tomography (CT) scanning of the head is vanishing signs of an infarct on the serial CT imaging in a patient with a recent stroke. It is a reversal of the hypodensity on the CT after an acute ischemic stroke. This happens as a result of re-nourishment of the infarcted area in subacute phase about one to three weeks after the stroke. In fact, resolution of the edema, which was caused by the accident, leads to increased attenuation of infarcted area that may regain near-normal density and mask the stroke. However, in the third week, parenchymal volume loss commonly appears as a hypoattenuation with a negative mass effect (shrinkage).

<span class="mw-page-title-main">Focal lung pneumatosis</span> Medical condition

A focal lung pneumatosis is an enclosed pocket of air or gas in the lung and includes blebs, bullae, pulmonary cysts, and lung cavities. Blebs and bullae can be classified by their wall thickness.

COVID-19 datasets are public databases for sharing case data and medical information related to the COVID-19 pandemic.

The empty delta sign is a radiologic sign seen on brain imaging which is associated with cerebral venous sinus thrombosis. It is usually seen on magnetic resonance imaging (MRI) or computed tomography (CT) scans with contrast. It is seen as dural wall enhancement in the absence of intra-sinus enhancement. This is due to the presence of a blood clot in the dural venous sinuses. The dural venous sinuses drain blood from the brain to the internal jugular veins, which in turn drains blood to the heart. It has been proposed that the empty delta sign occurs in dural venous thromboses due to contrast material filling the dural venous collateral circulation immediately surrounding the dura whilst being unable to fill the intra-dural sinus space due to the presence of a blood clot. The superior sagittal sinus is most commonly affected, but the radiologic sign may also be seen in the transverse sinuses.

Fat suppression is an MRI technique in which fat signal from adipose tissue is suppressed to better visualize uptake of contrast material by bodily tissues, reduce chemical shift artifact, and to characterize certain types of lesions such as adrenal gland tumors, bone marrow infiltration, fatty tumors, and steatosis by determining the fat content of the tissues. Due to short relaxation times, fat exhibits a strong signal in magnetic resonance imaging (MRI), easily discernible on scans.
