DICOM Viewer by CoreWare is an application that allows users to view DICOM images (images used for computer radiography). Unfortunately, DICOM Viewer for Mac is not available, but there are other tools that will help you view your DICOM images on Mac. Any of these programs can become a good alternative to DICOM Viewer for Mac. RadiAnt DICOM Viewer is one of those application, designed specifically for professionals and for medical students. The tool lets you view DICOM files, turn on annotations, enable the negative mode and add various types of measurement, like length, angle or ellipse.
- Dicom viewer open source or Dicom viewer online or Dicom viewer download are all ways to view medical image files. The features of these Dicom viewer software is that they are suited for patient CDs/DVDs.
- RadiAnt DICOM Viewer is built and tested specifically for Windows platform. We do not officially support RadiAnt on platforms other than Windows. Technically, RadiAnt can run on macOS systems using either the CrossOver MAC (paid) software or the open-source Wine software. However, some features may not be available or may cause program crashes.
The best free software solutions for DICOM images
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!
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!

Why we like it
We really like Collective Minds Radiology as it is a bit different to other sites. It's a radiology collaboration service and centered around sharing cases with other professionals for expertise, advice or teaching. It is free with unlimited storage, easy to use and fast. As it is cloud based, you can access it on pretty much any device. The service is restricted to medical professionals and sharing can be done to specific groups e.g. your hospital community. The ability for users to comment and tag images is particularly unique and great for learning and teaching.
