Radiopedia.org : A Free Educational Resource

 

 

Radiopedia hosts over 10,000 articles about radiography and this is definitely the place to go if you are looking to familiarize yourself with imaging techniques. The big pro of this website is that many of the articles are brief and you can easily zip through many topics that apply to your work as a medical translator. The text is usually very concise and fluent, but it does include multiple terms from various fields, and I would suggest adding a link to each term to transfer the reader to a relevant article or explanation. Take for example the article Introduction to MRI by Dr. Jeremy Jones et al., which briefly reviews the history of MRI imaging as well as the advantages and disadvantages of this imaging modality compared to CT and x-ray imaging techniques. You may want to go through the following useful definitions before reading this article:

  • Modality: a method of application or employment

  • Ionization: production of ions as a result of interaction of radiation with matter

  • Ion: an atom or group of atoms having a positive or negative electric charge

  • Imaging planes: oblique – passes through the body or an organ at an angle; coronal – runs vertically from right to left and divides the body into anterior and posterior portions; sagittal – a vertical plane that divides the body into right and left portions; axial – divides the body into superior and inferior parts (also called ‘horizontal plane’).

 

Another good thing about this website is that if you scroll all the way to the bottom, you can choose from a detailed list of related articles by different professionals, so you can selectively read about the topics that interest you in the field of radiology. This website is definitely a good place to start.

 

If this is your first encounter with MRI technology, I recommend reading MR physics by Dr. J. Ray Ballinger et al., which accurately and clearly explains the process through which MR images are created by describing the four stages of the basic image acquisition process: preparation, excitation, spatial encoding, and signal acquisition.
