I started using OsiriX around the year 2004, with version 1.6 introducing SUV calculations for PET. I had previously worked with softwares developed in our laboratory. The ergonomics of our softwares were adapted to the needs of the users and it appeared to me that OsiriX was designed with the same philosophy. Osirix rapidly became essential to my clinical and research work on PET-CT. Nowadays I use OsiriX for my clinical workflow in nuclear medicine, including PET-CT, SPECT-CT, planar and dynamic imaging.
Anyone who is looking for a platform-independent and multi-modal DICOM viewer for nuclear medicine should consider some of the following reasons why I have been using OsiriX for more than 10 years: It has optimal display of any DICOM modality with adapted color tools (e.g. fixed zero for nucmed images), comprehensive support of multi-modal imaging with relevant toolboxes and color look-up tables, 3D-surface rendering (e.g. bone SPECT-CT) and ease of use as the layout is intuitive making the learning curve very short for newbies. The premium support is very responsive, you get access to the developpers quite quickly and the integration within the hospital IT is really straightforward. It is also cost-effective as any analysis will demonstrate that OsiriX has no real competition as far as the features-to-cost ratio is concerned.
