Our goal is to provide concise and accessible resources for anyone interested in the fascinating field of interventional radiology.

Interventional radiology is better described as minimally-invasive image-guided surgery. Now that’s quite a mouthful so people often refer to the field simply as IR.

Interventional radiologists are a subset of doctors who interpret medical imaging and perform procedures under image guidance e.g. ultrasound, x-rays, fluoroscopy, computed tomography (CT) or magnetic resonance imaging (MRI). Typically these procedures are done ‘without a scalpel’ and use existing orifices or pinholes usually made with a needle, unlike traditional surgery.

Whether you are a medical student, junior doctor, or just a curious learner, IR Bites offers a variety of educational materials to help you expand your knowledge. From brief overviews of common procedures to in-depth explanations of more complex techniques, our content is designed to be informative, engaging, and easy to digest.

Our team has carefully curated a collection of resources to help you learn about the core practices in the field. We believe that education is a lifelong journey, and we are committed to providing you with the tools you need to stay up-to-date with the rapidly evolving world of interventional radiology. If you have any feedback, good or bad, please drop us a line as we love hearing your thoughts so we can improve the resources to better meet your needs.

So whether you’re studying for an exam, preparing for a procedure, or simply looking to broaden your knowledge, we invite you to explore IR Bites and discover the many ways in which we can help you become more informed and confident in interventional radiology.

Stay tuned for more updates and articles on the latest developments in interventional radiology. Remember to follow us on social media for additional bite-sized learning opportunities and resources.

TLA = Three Letter Acronyms

You won’t find three letter acronyms in IR Bites. The only acronym we use is IR = Interventional Radiology. Our content is designed to be readable by all people so we try our best to avoid acronyms and jargon. Sometimes we’ll use them in brackets following the full length words if the acronym is used conversationally more often than the actual words e.g. magnetic resonance imaging (MRI).
