Radiology Software

As a radiologist one needs to be at least a little tech savvy to optimize workflow. Here is a list of useful tools for radiology.

Dicom Viewers:

TL;DR Recommended DICOM viewers:
MacOS: Horos
Windows: Radiant viewer

MacOS DICOM viewer

Osirix MD

Osirix DICOM image viewer

    • Best DICOM software available for image interpretation and processing.
    • Unfortunately ONLY available for the MacOS and is a paid software.
    • Best viewed on 21.5/27 inch iMac systems.
    • A good alternative for radiology centers who cannot afford the iMac PC are these small Mac Mini PC boxes. These are standalone CPU boxes , to which you can attach your own monitor and ports.
    • Osirix is available as a bundled solution with iMacs. You can contact Indian vendors like this one.
    • Excellent tutorials for using Osirix are available here: Osirix UK user group.

  • Download Osirix Lite


Miele-LXIV DICOM viewer logo

  • Miele-LXIV is a DICOM workstation and viewer.
  • The project started in November 2014 as a fork of the popular open source 32-bit project OsiriX, but it has been modified to become a 64-bit application and to remove many of the limitations of the 32-bit version.
  • Was earlier known as Osirix-LXIV.
  • Robust viewer with a host of features including 2D and 3D viewing and 64 bit DICOM printing. Here is the entire feature list.

Radiology Reporting tools:

Radiology reporting at almost all institutes is done on computers. Typing is often a nightmare for first year radiology residents. There is no escaping this so the best way is to find solutions.

The more time to save time on reporting the more time you have to interpret images.

Word processors

Microsoft Word

    • Needs no introduction.
    • Best word processing software for reporting.
    • One should learn basic hacks to cut down typing times. One of the best tool you can use is the AutoCorrect tool. You can save normal/ abnormal CT/MR/USG/Radiograph formats as shortcuts. For example I have saved a normal CT abdomen male study as a “nabdmale”. When I type the shortcut the entire normal template (with the formatting) will show up..In older versions you can also use the AutoComplete feature. Here is a video tutorial:
    • Cons:
      • No free version available, takes lot of space at times and slows the system at times.

Free alternatives to Word:

Google Docs:

  • If you work in a department with internet connectivity this is the best option.
  • You don’t need to worry about data loss as Google automatically saves your edits online.
  • It also so stores multiple versions of your documents so that you can go back to the previous version in case you want to.
  • Also you can access it from multiple PCs as the documents are synced on the web platform.

  • Free alternative to MS Office.
  • Includes a free alternative to word,  powerpoint and excel.
  • You should save documents in the MS office formats (doc/ ppt / xls) to avoid conflicts while using it on other systems.
  • Download it for free here: Download Open Office.
  • Similar alternatives include:


  • Standalone word processor.
  • No need to install the entire MS Office / OpenOffice suite.
  • Small program so won’t take up a lot of space.
  • Download it here. AbiWord


      • This is not a word processing software but its an alternative to the AutoCorrect/ AutoText option of MS Word that we discussed.
      • Especially useful for radiology residents working in institutes with an online reporting system where the typing has to be done in a browser rather than a word processor.
      • You can store your desired templates which will get triggered as you type the designated shortcuts. For eg You can store the format for acute pancreatitis as a short code “AP”. So when you type the short code the entire report will come up and you can then edit the specific findings in your particular case in the template.
      • Quite handy and saves a lot of time.
      • Works in word as well.
      • Another cool thing is that you can export the shortcuts that you have saved and then import the same in other computers in your department as well.
      • Here is a video tutorial:

Text-To-Word software

Nuance Dragon Medical Practice Edition / PowerScribe:

Google text-to-speech engine

    • A free alternative to costly speech to text software.
    • Simply use the speech to text feature on the Google keyboard in your smartphone.
    • You can also use it on Google Docs online:



IndexYourFiles (IFY)

    • Most of the radiology departments in India do not have EMR (Electronic Medical Records) currently. Radiology reports are usually saved in Word format , segregated month wise and modality wise. Often you need to find the previous report of a patient who has now come for a follow up. Doing that using the search function of Windows can be a pain if there are thousands of documents , which is usually the case for most radiology departments.
    • Soultion? – IndexYourFiles (IFY)!
    • What it does is index all the files in a particular directory and fastens the search process.
    • It also support network shared drives. For eg. You can search for CT records of the patient from the MRI reporting computer , provided the folders are shared.
    • Its a small but quite handy software and saves a lot of time.
    • Whats good is that it even comes in a portable version so no need to install it.
