The best free software solutions for DICOM images

RadiAnt DICOM Viewer 2020.2 has been available for download for some time now. This versions brings DSA (Digital Subtraction Angiography) to the table. There is an option to set the precise WL/WW values (or SUVbw for PET studies) and to easily create own windowing presets (in 2D, 3D MPR and 3D VR viewers). LEARN MORE OnePacs provides range of Viewer options to meet the individual preferences of each physician. OnePacs is also compatible with DICOM compliant viewers and Mac-based viewers including Osirix.

Please note: There are many free DICOM viewers online, however many lack the core functionality required by a radiologist for reviewing studies and/or teaching. All software on this page has been downloaded / tested by a consultant radiologist and thought to represent the best currently available online. This page is updated regularly.

Sometimes it's useful to be able to view and manipulate medical images such as X-rays, CT or MRI scans on your own PC, laptop or tablet. This is particularly important when preparing teaching files or practising for your radiology exams. Finding a good free DICOM viewer can be tricky, especially as there are so many options out there. We have tested may different applications (so you don't have to) and the following are our best picks. We grouped them according to the operating system used because unfortunately there aren't any free viewers that run on both!

DICOM stands for 'Digital Imaging and Communications in Medicine'. It is the standard for handling, storing, printing, and transmitting information in medical imaging. DICOM viewing software allows radiology trainees and consultants to view and manipulate medical images (such as radiographs or MRI scans) on their own PC, laptop or tablet. In the hospital environment, this forms part of the picture archiving and communication system (PACS), which doctors will be familiar with!

A popular software for radiologists working in the UK is currently a programme called 'Horos'. This is a free open source version of the software used by the Royal College of Radiologists for the viva part of the Final FRCR 2B exam, so obviously it makes sense to use it for teaching as well. This programme is only available on Apple computers, hence why so many radiologists own MacBooks.

There is a paid version of Horos called 'OsiriX MD', which is produced by Pixmeo, however it is expensive so not ideal for basic teaching purposes, although has great functionality. Pixemo also produce a free demo version called 'OsiriX Lite', however there are major limitations placed on this including pop-ups asking you to upgrade to the paid version, performance restrictions, image viewing restrictions and inability to edit the meta-data attached to DICOM images - for example you can't easily re-order series within a study, which may be important if you are preparing cases for teaching or examinations. It is for these reasons that we do not list OsiriX Lite in our recommendations.

The OsiriX UK user group are a group of Radiologists in the UK who are keen on digital radiology education and use OsiriX/Horos for teaching. The aim is to achieve a nationally agreed consensus on how cases are collected, organised and used for teaching and examination and thereby achieve a collective common ground/platform/standard for radiology education across the country. The resources on this site are amazing so we recommend you visit it now!

Why we like it

We really like Horos as it is a free open source version of the same software as that used by The Royal College of Radiologists for the viva part of the final FRCR (Part B) exam. Becoming familiar with Horos will help radiology trainees when preparing for this exam. Horos is easy to use and as a full 64-bit medical image viewer for Mac there is a huge amount of functionality contained within. It is updated regularly. We believe Horos is the best free DICOM viewer for Apple MacOS.

Interestingly, Horos is named after the Egyptian god Horus, son of Osiris and Isis. Horos is a based on OsiriX (a similar paid-for medical viewer), named after Osiris. The developers obviously appreciate Egyptian and greek mythology!

There is a useful Mac plug-in for Horos that allows you to quickly upload selected studies / images to Radiopaedia, a free educational radiology resource with one of the web's largest collections of radiology cases and reference articles.
