Projectional radiography is the bread and butter of radiology; patients will often interact with medical imaging in some form or another through their journey.

The radiographic indications project was an editorial project that ran from April 2020 until January 2021 to edit and create radiography articles to include specific projectional indications.

We created indications for 189 radiography articles over this period, an impressive effort performed by a great team.

We hope this can be a tool for both referrers and radiographers to ensure they perform the correct exam for a valid reason and understand what exams will yield the highest diagnostic value. 

You can peruse our radiography articles, both adult and pediatric, among other things in our imaging in practice section

A team of 14 editors contributed to this project, and our thanks (in alphabetical order) go to:

Andrew is one of Radiopaedia's managing editors and a radiographer based in Brisbane, Australia.
He started this project due to the fact, during a night shift, he forgot which axial shoulder to perform. and the American Society of Neuroradiology (ASNR)  are again collaborating on giving you all the opportunity to submit an adult brain case to ASNR 2021 Case of the Day. 

Each day during the  ASNR 59th Annual Meeting (May 22-26, 2021), a case will be shown as the official Case of the Day. This had traditionally been 'invite-only', but for a number of years, one of the cases will be chosen from cases you submit to 

In addition to one ASNR 2021 case of the day winner, we will also be showcasing a number of the best submissions as our very own 'cases of the day' on our home page and through social media. And, even better, you will be contributing to your personal case library and making even better! 


There are a number of prizes available: 


The winner gets two awesome prizes:

  1. ASNR21 Waived Registration Fee (value of USD$300). The prize is courtesy of the American Society of Neuroradiology (ASNR). The prize is not transferable or able to be postponed to a future meeting.

    If you have any questions, please contact Erica Kruse, ASNR Director of Education, 630-574-0220, Ext. 229 or email [email protected]

  2. 12-month all-access pass to Radiopaedia's online courses valued at USD$480.  

The editorial team will be selecting a runner-up who will receive a 12-month all-access pass to Radiopaedia's online courses valued at USD$480.

Submitting a case

To make your case eligible for the ASNR 2021 Case of the Day, simply:

  1. upload an awesome Adult Brain Case (see below)
  2. add the tag "ASNR2021" in the right-hand column of the case edit page (make sure you use ALL CAPS)

Please make sure that your case is fully fleshed out (see our case publishing guidelines

Submitting a case is easy, especially if you are using one of our case uploaders. If not, then you can do it the old-fashioned browser-based way. If you are not already familiar with how this works, the following learning pathway is the best way to get ready. 

How to create cases 


Submissions close on Monday, February 15th 2021, and the winner will be chosen by the ASNR committee in the following couple of weeks. The winner will then be contacted by email, so please make sure the email listed in your profile is correct. 


The winning case will then be adapted by ASNR conveyors into one or more slides. You, our dear contributor, will not be required to do anything.

A fantastic international team of editors were behind this incredible effort including:

  • Dr Pir Abdul Ahad Aziz, radiologist, Pakistan (project lead)
  • Dr Magdalena Chmiel-Nowak, radiologist, Poland
  • Dr Henry Knipe, radiologist, Australia
  • Dr Edgar Lorente, radiologist, Spain
  • Dr Tim Luijkx, radiologist, Australia
  • Dr Matt A. Morgan, radiologist, United States of America

RCR2020 Case Contest

We are thrilled to be helping the Royal College of Radiologists with its RCR2020 Digital Learning Programme. During this event, we are holding a joint prize-winning online case contest, supported by Medica. This contest will be open not only to RCR2020 delegates but, in the spirit of Radiopaedia, anyone in the whole wide world. This is our way of helping to make RCR2020 a truly global education event. 


The contest runs over three weeks, with five cases per week. The first set of five cases will be published online on Monday, September 21st 2020 at 0500 UTC, with further sets available on each of the following two Mondays. The answers and winners will be revealed on the weekend immediately following each week of cases.

Officially accredited CPD points are available for each case. 


Awaiting those who get any of the cases correct is not only immense intellectual satisfaction, fame and glory, there are lots of prizes on offer too.

Prizes for RCR delegates

Each week, one RCR2020 delegate can win access to any one-day RCR event during 2021 (including one of the days of RCR2021). The RCR2020 delegate with the best overall results across the whole contest will also have the opportunity to win a grand prize, an iPad, sponsored by Medica.

Prizes for all other participants

Each week, one non-delegate can win a Radiopaedia All-Access Pass, worth $480 (USD).
